ASoC: Fixes for v5.5
This is mostly driver specific fixes, plus an error handling fix
in the core. There is a rather large diffstat for the stm32 SAI
driver, this is a very large but mostly mechanical update which
wraps every register access in the driver to allow a fix to the
locking which avoids circular locks, the active change is much
smaller and more reasonably sized.

+iTLB multihit
+=============
+
+iTLB multihit is an erratum where some processors may incur a machine check
+error, possibly resulting in an unrecoverable CPU lockup, when an
+instruction fetch hits multiple entries in the instruction TLB. This can
+occur when the page size is changed along with either the physical address
+or cache type. A malicious guest running on a virtualized system can
+exploit this erratum to perform a denial of service attack.
+
+
+Affected processors
+-------------------
+
+Variations of this erratum are present on most Intel Core and Xeon processor
+models. The erratum is not present on:
+
+ - non-Intel processors
+
+ - Some Atoms (Airmont, Bonnell, Goldmont, GoldmontPlus, Saltwell, Silvermont)
+
+ - Intel processors that have the PSCHANGE_MC_NO bit set in the
+ IA32_ARCH_CAPABILITIES MSR.
+
+
+Related CVEs
+------------
+
+The following CVE entry is related to this issue:
+
+ ============== =================================================
+ CVE-2018-12207 Machine Check Error Avoidance on Page Size Change
+ ============== =================================================
+
+
+Problem
+-------
+
+Privileged software, including OS and virtual machine managers (VMM), are in
+charge of memory management. A key component in memory management is the control
+of the page tables. Modern processors use virtual memory, a technique that creates
+the illusion of a very large memory for processors. This virtual space is split
+into pages of a given size. Page tables translate virtual addresses to physical
+addresses.
+
+To reduce latency when performing a virtual to physical address translation,
+processors include a structure, called TLB, that caches recent translations.
+There are separate TLBs for instruction (iTLB) and data (dTLB).
+
+Under this errata, instructions are fetched from a linear address translated
+using a 4 KB translation cached in the iTLB. Privileged software modifies the
+paging structure so that the same linear address using large page size (2 MB, 4
+MB, 1 GB) with a different physical address or memory type. After the page
+structure modification but before the software invalidates any iTLB entries for
+the linear address, a code fetch that happens on the same linear address may
+cause a machine-check error which can result in a system hang or shutdown.
+
+
+Attack scenarios
+----------------
+
+Attacks against the iTLB multihit erratum can be mounted from malicious
+guests in a virtualized system.
+
+
+iTLB multihit system information
+--------------------------------
+
+The Linux kernel provides a sysfs interface to enumerate the current iTLB
+multihit status of the system:whether the system is vulnerable and which
+mitigations are active. The relevant sysfs file is:
+
+/sys/devices/system/cpu/vulnerabilities/itlb_multihit
+
+The possible values in this file are:
+
+.. list-table::
+
+ * - Not affected
+ - The processor is not vulnerable.
+ * - KVM: Mitigation: Split huge pages
+ - Software changes mitigate this issue.
+ * - KVM: Vulnerable
+ - The processor is vulnerable, but no mitigation enabled
+
+
+Enumeration of the erratum
+--------------------------------
+
+A new bit has been allocated in the IA32_ARCH_CAPABILITIES (PSCHANGE_MC_NO) msr
+and will be set on CPU's which are mitigated against this issue.
+
+ ======================================= =========== ===============================
+ IA32_ARCH_CAPABILITIES MSR Not present Possibly vulnerable,check model
+ IA32_ARCH_CAPABILITIES[PSCHANGE_MC_NO] '0' Likely vulnerable,check model
+ IA32_ARCH_CAPABILITIES[PSCHANGE_MC_NO] '1' Not vulnerable
+ ======================================= =========== ===============================
+
+
+Mitigation mechanism
+-------------------------
+
+This erratum can be mitigated by restricting the use of large page sizes to
+non-executable pages. This forces all iTLB entries to be 4K, and removes
+the possibility of multiple hits.
+
+In order to mitigate the vulnerability, KVM initially marks all huge pages
+as non-executable. If the guest attempts to execute in one of those pages,
+the page is broken down into 4K pages, which are then marked executable.
+
+If EPT is disabled or not available on the host, KVM is in control of TLB
+flushes and the problematic situation cannot happen. However, the shadow
+EPT paging mechanism used by nested virtualization is vulnerable, because
+the nested guest can trigger multiple iTLB hits by modifying its own
+(non-nested) page tables. For simplicity, KVM will make large pages
+non-executable in all shadow paging modes.
+
+Mitigation control on the kernel command line and KVM - module parameter
+------------------------------------------------------------------------
+
+The KVM hypervisor mitigation mechanism for marking huge pages as
+non-executable can be controlled with a module parameter "nx_huge_pages=".
+The kernel command line allows to control the iTLB multihit mitigations at
+boot time with the option "kvm.nx_huge_pages=".
+
+The valid arguments for these options are:
+
+ ========== ================================================================
+ force Mitigation is enabled. In this case, the mitigation implements
+ non-executable huge pages in Linux kernel KVM module. All huge
+ pages in the EPT are marked as non-executable.
+ If a guest attempts to execute in one of those pages, the page is
+ broken down into 4K pages, which are then marked executable.
+
+ off Mitigation is disabled.
+
+ auto Enable mitigation only if the platform is affected and the kernel
+ was not booted with the "mitigations=off" command line parameter.
+ This is the default option.
+ ========== ================================================================
+
+
+Mitigation selection guide
+--------------------------
+
+1. No virtualization in use
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+ The system is protected by the kernel unconditionally and no further
+ action is required.
+
+2. Virtualization with trusted guests
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+ If the guest comes from a trusted source, you may assume that the guest will
+ not attempt to maliciously exploit these errata and no further action is
+ required.
+
+3. Virtualization with untrusted guests
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+ If the guest comes from an untrusted source, the guest host kernel will need
+ to apply iTLB multihit mitigation via the kernel command line or kvm
+ module parameter.

+TAA - TSX Asynchronous Abort
+======================================
+
+TAA is a hardware vulnerability that allows unprivileged speculative access to
+data which is available in various CPU internal buffers by using asynchronous
+aborts within an Intel TSX transactional region.
+
+Affected processors
+-------------------
+
+This vulnerability only affects Intel processors that support Intel
+Transactional Synchronization Extensions (TSX) when the TAA_NO bit (bit 8)
+is 0 in the IA32_ARCH_CAPABILITIES MSR. On processors where the MDS_NO bit
+(bit 5) is 0 in the IA32_ARCH_CAPABILITIES MSR, the existing MDS mitigations
+also mitigate against TAA.
+
+Whether a processor is affected or not can be read out from the TAA
+vulnerability file in sysfs. See :ref:`tsx_async_abort_sys_info`.
+
+Related CVEs
+------------
+
+The following CVE entry is related to this TAA issue:
+
+ ============== ===== ===================================================
+ CVE-2019-11135 TAA TSX Asynchronous Abort (TAA) condition on some
+ microprocessors utilizing speculative execution may
+ allow an authenticated user to potentially enable
+ information disclosure via a side channel with
+ local access.
+ ============== ===== ===================================================
+
+Problem
+-------
+
+When performing store, load or L1 refill operations, processors write
+data into temporary microarchitectural structures (buffers). The data in
+those buffers can be forwarded to load operations as an optimization.
+
+Intel TSX is an extension to the x86 instruction set architecture that adds
+hardware transactional memory support to improve performance of multi-threaded
+software. TSX lets the processor expose and exploit concurrency hidden in an
+application due to dynamically avoiding unnecessary synchronization.
+
+TSX supports atomic memory transactions that are either committed (success) or
+aborted. During an abort, operations that happened within the transactional region
+are rolled back. An asynchronous abort takes place, among other options, when a
+different thread accesses a cache line that is also used within the transactional
+region when that access might lead to a data race.
+
+Immediately after an uncompleted asynchronous abort, certain speculatively
+executed loads may read data from those internal buffers and pass it to dependent
+operations. This can be then used to infer the value via a cache side channel
+attack.
+
+Because the buffers are potentially shared between Hyper-Threads cross
+Hyper-Thread attacks are possible.
+
+The victim of a malicious actor does not need to make use of TSX. Only the
+attacker needs to begin a TSX transaction and raise an asynchronous abort
+which in turn potenitally leaks data stored in the buffers.
+
+More detailed technical information is available in the TAA specific x86
+architecture section: :ref:`Documentation/x86/tsx_async_abort.rst <tsx_async_abort>`.
+
+
+Attack scenarios
+----------------
+
+Attacks against the TAA vulnerability can be implemented from unprivileged
+applications running on hosts or guests.
+
+As for MDS, the attacker has no control over the memory addresses that can
+be leaked. Only the victim is responsible for bringing data to the CPU. As
+a result, the malicious actor has to sample as much data as possible and
+then postprocess it to try to infer any useful information from it.
+
+A potential attacker only has read access to the data. Also, there is no direct
+privilege escalation by using this technique.
+
+
+.. _tsx_async_abort_sys_info:
+
+TAA system information
+-----------------------
+
+The Linux kernel provides a sysfs interface to enumerate the current TAA status
+of mitigated systems. The relevant sysfs file is:
+
+/sys/devices/system/cpu/vulnerabilities/tsx_async_abort
+
+The possible values in this file are:
+
+.. list-table::
+
+ * - 'Vulnerable'
+ - The CPU is affected by this vulnerability and the microcode and kernel mitigation are not applied.
+ * - 'Vulnerable: Clear CPU buffers attempted, no microcode'
+ - The system tries to clear the buffers but the microcode might not support the operation.
+ * - 'Mitigation: Clear CPU buffers'
+ - The microcode has been updated to clear the buffers. TSX is still enabled.
+ * - 'Mitigation: TSX disabled'
+ - TSX is disabled.
+ * - 'Not affected'
+ - The CPU is not affected by this issue.
+
+.. _ucode_needed:
+
+Best effort mitigation mode
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If the processor is vulnerable, but the availability of the microcode-based
+mitigation mechanism is not advertised via CPUID the kernel selects a best
+effort mitigation mode. This mode invokes the mitigation instructions
+without a guarantee that they clear the CPU buffers.
+
+This is done to address virtualization scenarios where the host has the
+microcode update applied, but the hypervisor is not yet updated to expose the
+CPUID to the guest. If the host has updated microcode the protection takes
+effect; otherwise a few CPU cycles are wasted pointlessly.
+
+The state in the tsx_async_abort sysfs file reflects this situation
+accordingly.
+
+
+Mitigation mechanism
+--------------------
+
+The kernel detects the affected CPUs and the presence of the microcode which is
+required. If a CPU is affected and the microcode is available, then the kernel
+enables the mitigation by default.
+
+
+The mitigation can be controlled at boot time via a kernel command line option.
+See :ref:`taa_mitigation_control_command_line`.
+
+.. _virt_mechanism:
+
+Virtualization mitigation
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Affected systems where the host has TAA microcode and TAA is mitigated by
+having disabled TSX previously, are not vulnerable regardless of the status
+of the VMs.
+
+In all other cases, if the host either does not have the TAA microcode or
+the kernel is not mitigated, the system might be vulnerable.
+
+
+.. _taa_mitigation_control_command_line:
+
+Mitigation control on the kernel command line
+---------------------------------------------
+
+The kernel command line allows to control the TAA mitigations at boot time with
+the option "tsx_async_abort=". The valid arguments for this option are:
+
+ ============ =============================================================
+ off This option disables the TAA mitigation on affected platforms.
+ If the system has TSX enabled (see next parameter) and the CPU
+ is affected, the system is vulnerable.
+
+ full TAA mitigation is enabled. If TSX is enabled, on an affected
+ system it will clear CPU buffers on ring transitions. On
+ systems which are MDS-affected and deploy MDS mitigation,
+ TAA is also mitigated. Specifying this option on those
+ systems will have no effect.
+
+ full,nosmt The same as tsx_async_abort=full, with SMT disabled on
+ vulnerable CPUs that have TSX enabled. This is the complete
+ mitigation. When TSX is disabled, SMT is not disabled because
+ CPU is not vulnerable to cross-thread TAA attacks.
+ ============ =============================================================
+
+Not specifying this option is equivalent to "tsx_async_abort=full".
+
+The kernel command line also allows to control the TSX feature using the
+parameter "tsx=" on CPUs which support TSX control. MSR_IA32_TSX_CTRL is used
+to control the TSX feature and the enumeration of the TSX feature bits (RTM
+and HLE) in CPUID.
+
+The valid options are:
+
+ ============ =============================================================
+ off Disables TSX on the system.
+
+ Note that this option takes effect only on newer CPUs which are
+ not vulnerable to MDS, i.e., have MSR_IA32_ARCH_CAPABILITIES.MDS_NO=1
+ and which get the new IA32_TSX_CTRL MSR through a microcode
+ update. This new MSR allows for the reliable deactivation of
+ the TSX functionality.
+
+ on Enables TSX.
+
+ Although there are mitigations for all known security
+ vulnerabilities, TSX has been known to be an accelerator for
+ several previous speculation-related CVEs, and so there may be
+ unknown security risks associated with leaving it enabled.
+
+ auto Disables TSX if X86_BUG_TAA is present, otherwise enables TSX
+ on the system.
+ ============ =============================================================
+
+Not specifying this option is equivalent to "tsx=off".
+
+The following combinations of the "tsx_async_abort" and "tsx" are possible. For
+affected platforms tsx=auto is equivalent to tsx=off and the result will be:
+
+ ========= ========================== =========================================
+ tsx=on tsx_async_abort=full The system will use VERW to clear CPU
+ buffers. Cross-thread attacks are still
+ possible on SMT machines.
+ tsx=on tsx_async_abort=full,nosmt As above, cross-thread attacks on SMT

+ tsx=on tsx_async_abort=off The system is vulnerable.
+ tsx=off tsx_async_abort=full TSX might be disabled if microcode

+ system is not vulnerable.
+ tsx=off tsx_async_abort=full,nosmt Ditto
+ tsx=off tsx_async_abort=off ditto
+ ========= ========================== =========================================
+
+
+For unaffected platforms "tsx=on" and "tsx_async_abort=full" does not clear CPU

+"tsx" command line argument has no effect.

+
+Mitigation selection guide
+--------------------------
+
+1. Trusted userspace and guests
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If all user space applications are from a trusted source and do not execute
+untrusted code which is supplied externally, then the mitigation can be
+disabled. The same applies to virtualized environments with trusted guests.
+
+
+2. Untrusted userspace and guests
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If there are untrusted applications or guests on the system, enabling TSX
+might allow a malicious actor to leak data from the host or from other
+processes running on the same physical core.
+
+If the microcode is available and the TSX is disabled on the host, attacks
+are prevented in a virtualized environment as well, even if the VMs do not
+explicitly enable the mitigation.

Software can "opt-in" to receiving VAs from a 52-bit space by
specifying an mmap hint parameter that is larger than 48-bit.

For example:

It's possible to use a buffer allocated via :c:func:`vmalloc()`, for
-example, for an intermediate buffer. Since the allocated pages are not
-contiguous, you need to set the ``page`` callback to obtain the physical
-address at every offset.
-
-The easiest way to achieve it would be to use
-:c:func:`snd_pcm_lib_alloc_vmalloc_buffer()` for allocating the buffer
-via :c:func:`vmalloc()`, and set :c:func:`snd_pcm_sgbuf_ops_page()` to
-the ``page`` callback. At release, you need to call
-:c:func:`snd_pcm_lib_free_vmalloc_buffer()`.
-
-If you want to implementation the ``page`` manually, it would be like
-this:
+example, for an intermediate buffer. In the recent version of kernel,
+you can simply allocate it via standard
+:c:func:`snd_pcm_lib_malloc_pages()` and co after setting up the
+buffer preallocation with ``SNDRV_DMA_TYPE_VMALLOC`` type.
::
- #include <linux/vmalloc.h>
+ snd_pcm_set_managed_buffer_all(pcm, SNDRV_DMA_TYPE_VMALLOC,
+ NULL, 0, 0);
- /* get the physical page pointer on the given offset */
- static struct page *mychip_page(struct snd_pcm_substream *substream,
- unsigned long offset)
- {
- void *pageptr = substream->runtime->dma_area + offset;
- return vmalloc_to_page(pageptr);
- }
+The NULL is passed to the device pointer argument, which indicates
+that the default pages (GFP_KERNEL and GFP_HIGHMEM) will be
+allocated.
+
+Also, note that zero is passed to both the size and the max size
+arguments here. Since each vmalloc call should succeed at any time,
+we don't need to pre-allocate the buffers like other continuous
+pages.
+
+If you need the 32bit DMA allocation, pass the device pointer encoded
+by :c:func:`snd_dma_continuous_data()` with ``GFP_KERNEL|__GFP_DMA32``
+argument.
+
+::
+
+ snd_pcm_set_managed_buffer_all(pcm, SNDRV_DMA_TYPE_VMALLOC,
+ snd_dma_continuous_data(GFP_KERNEL | __GFP_DMA32), 0, 0);

-- Initial Revision
-
-
-Overview
-========
-
-This README will address issues regarding how to configure the kernel
-to access a RIO 500 mp3 player.
-Before I explain how to use this to access the Rio500 please be warned:
-
-.. warning::
-
- Please note that this software is still under development. The authors
- are in no way responsible for any damage that may occur, no matter how
- inconsequential.
-
-It seems that the Rio has a problem when sending .mp3 with low batteries.
-I suggest when the batteries are low and you want to transfer stuff that you
-replace it with a fresh one. In my case, what happened is I lost two 16kb
-blocks (they are no longer usable to store information to it). But I don't
-know if that's normal or not; it could simply be a problem with the flash
-memory.
-
-In an extreme case, I left my Rio playing overnight and the batteries wore
-down to nothing and appear to have corrupted the flash memory. My RIO
-needed to be replaced as a result. Diamond tech support is aware of the
-problem. Do NOT allow your batteries to wear down to nothing before
-changing them. It appears RIO 500 firmware does not handle low battery
-power well at all.
-
-On systems with OHCI controllers, the kernel OHCI code appears to have
-power on problems with some chipsets. If you are having problems
-connecting to your RIO 500, try turning it on first and then plugging it
-into the USB cable.
-
-Contact Information
--------------------
-
- The main page for the project is hosted at sourceforge.net in the following
- URL: <http://rio500.sourceforge.net>. You can also go to the project's
- sourceforge home page at: <http://sourceforge.net/projects/rio500/>.
- There is also a mailing list: rio500-users@lists.sourceforge.net
-
-Authors
--------
-
-Most of the code was written by Cesar Miquel <miquel@df.uba.ar>. Keith
-Clayton <kclayton@jps.net> is incharge of the PPC port and making sure
-things work there. Bruce Tenison <btenison@dibbs.net> is adding support
-for .fon files and also does testing. The program will mostly sure be
-re-written and Pete Ikusz along with the rest will re-design it. I would
-also like to thank Tri Nguyen <tmn_3022000@hotmail.com> who provided use
-with some important information regarding the communication with the Rio.
-
-Additional Information and userspace tools
-
- http://rio500.sourceforge.net/
-
-
-Requirements
-============
-
-A host with a USB port running a Linux kernel with RIO 500 support enabled.
-
-The driver is a module called rio500, which should be automatically loaded
-as you plug in your device. If that fails you can manually load it with
-
- modprobe rio500
-
-Udev should automatically create a device node as soon as plug in your device.
-If that fails, you can manually add a device for the USB rio500::
-
- mknod /dev/usb/rio500 c 180 64
-
-In that case, set appropriate permissions for /dev/usb/rio500 (don't forget
-about group and world permissions). Both read and write permissions are
-required for proper operation.
-
-That's it. The Rio500 Utils at: http://rio500.sourceforge.net should
-be able to access the rio500.
-
-Limits
-======
-
-You can use only a single rio500 device at a time with your computer.
-
-Bugs
-====
-
-If you encounter any problems feel free to drop me an email.

+TSX Async Abort (TAA) mitigation
+================================
+
+.. _tsx_async_abort:
+
+Overview
+--------
+
+TSX Async Abort (TAA) is a side channel attack on internal buffers in some
+Intel processors similar to Microachitectural Data Sampling (MDS). In this
+case certain loads may speculatively pass invalid data to dependent operations
+when an asynchronous abort condition is pending in a Transactional
+Synchronization Extensions (TSX) transaction. This includes loads with no
+fault or assist condition. Such loads may speculatively expose stale data from
+the same uarch data structures as in MDS, with same scope of exposure i.e.
+same-thread and cross-thread. This issue affects all current processors that
+support TSX.
+
+Mitigation strategy
+-------------------
+
+a) TSX disable - one of the mitigations is to disable TSX. A new MSR
+IA32_TSX_CTRL will be available in future and current processors after
+microcode update which can be used to disable TSX. In addition, it
+controls the enumeration of the TSX feature bits (RTM and HLE) in CPUID.
+
+b) Clear CPU buffers - similar to MDS, clearing the CPU buffers mitigates this
+vulnerability. More details on this approach can be found in
+:ref:`Documentation/admin-guide/hw-vuln/mds.rst <mds>`.
+
+Kernel internal mitigation modes
+--------------------------------
+
+ ============= ============================================================
+ off Mitigation is disabled. Either the CPU is not affected or
+ tsx_async_abort=off is supplied on the kernel command line.
+
+ tsx disabled Mitigation is enabled. TSX feature is disabled by default at
+ bootup on processors that support TSX control.
+
+ verw Mitigation is enabled. CPU is affected and MD_CLEAR is
+ advertised in CPUID.
+
+ ucode needed Mitigation is enabled. CPU is affected and MD_CLEAR is not
+ advertised in CPUID. That is mainly for virtualization
+ scenarios where the host has the updated microcode but the
+ hypervisor does not expose MD_CLEAR in CPUID. It's a best
+ effort approach without guarantee.
+ ============= ============================================================
+
+If the CPU is affected and the "tsx_async_abort" kernel command line parameter is
+not provided then the kernel selects an appropriate mitigation depending on the
+status of RTM and MD_CLEAR CPUID bits.
+
+Below tables indicate the impact of tsx=on|off|auto cmdline options on state of
+TAA mitigation, VERW behavior and TSX feature for various combinations of
+MSR_IA32_ARCH_CAPABILITIES bits.
+

+========= ========= ============ ============ ============== =================== ======================
+
+In the tables, TSX_CTRL_MSR is a new bit in MSR_IA32_ARCH_CAPABILITIES that
+indicates whether MSR_IA32_TSX_CTRL is supported.
+
+There are two control bits in IA32_TSX_CTRL MSR:
+
+ Bit 0: When set it disables the Restricted Transactional Memory (RTM)
+ sub-feature of TSX (will force all transactions to abort on the
+ XBEGIN instruction).
+
+ Bit 1: When set it disables the enumeration of the RTM and HLE feature
+ (i.e. it will make CPUID(EAX=7).EBX{bit4} and
+ CPUID(EAX=7).EBX{bit11} read as 0).

+ On Cavium ThunderX2, a load, store or prefetch instruction between a

+
+ Work around the issue by avoiding the problematic code sequence and

+ Intel's TSX (Transactional Synchronization Extensions) feature
+ allows to optimize locking protocols through lock elision which
+ can lead to a noticeable performance boost.
+
+ On the other hand it has been shown that TSX can be exploited
+ to form side channel attacks (e.g. TAA) and chances are there
+ will be more of those attacks discovered in the future.
+
+ Therefore TSX is not enabled by default (aka tsx=off). An admin
+ might override this decision by tsx=on the command line parameter.
+ Even with TSX enabled, the kernel will attempt to enable the best
+ possible TAA mitigation setting depending on the microcode available
+ for the particular machine.
+
+ This option allows to set the default tsx mode between tsx=on, =off
+ and =auto. See Documentation/admin-guide/kernel-parameters.txt for more
+ details.
+
+ Say off if not sure, auto if TSX is in use but it should be used on safe
+ platforms or on if TSX is in use and the security aspect of tsx is not
+ relevant.

+
+What: /sys/accessibility/speakup/bleeps

+
+What: /sys/accessibility/speakup/keymap
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Speakup keymap remaps keys to Speakup functions.
+ It uses a binary
+ format. A special program called genmap is needed to compile a
+ textual keymap into the binary format which is then loaded into
+ /sys/accessibility/speakup/keymap.
+
+What: /sys/accessibility/speakup/no_interrupt
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Controls if typing interrupts output from speakup. With
+ no_interrupt set to zero, typing on the keyboard will interrupt
+ speakup if for example
+ the say screen command is used before the

+ With no_interrupt set to one, if the say

+
+What: /sys/accessibility/speakup/punc_level
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Controls the level of punctuation spoken as the screen is
+ displayed, not reviewed. Levels range from zero no punctuation,
+ to four, all punctuation. One corresponds to punc_some, two
+ corresponds to punc_most, and three as well as four both
+ correspond to punc_all. Some hardware synthesizers may have
+ different levels each corresponding to three and four for
+ punc_level. Also note that if punc_level is set to zero, and
+ key_echo is set to one, typed punctuation is still spoken as it
+ is typed.
+
+What: /sys/accessibility/speakup/punc_most
+KernelVersion: 2.6

+
+What: /sys/accessibility/speakup/reading_punc
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Almost the same as punc_level, the differences being that
+ reading_punc controls the level of punctuation when reviewing
+ the screen with speakup's screen review commands. The other
+ difference is that reading_punc set to three speaks punc_all,
+ and reading_punc set to four speaks all punctuation, including
+ spaces.
+
+What: /sys/accessibility/speakup/repeats
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: A list of characters speakup repeats. Normally, when there are
+ more than three characters in a row, speakup
+ just reads three of
+ those characters. For example, "......" would be read as dot,
+ dot, dot. If a . is added to the list of characters in repeats,
+ "......" would be read as dot, dot, dot, times six.
+
+What: /sys/accessibility/speakup/say_control
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org

+Description: Here, you will find a list of names for Speakup functions.
+ These are used by the help system. For example, suppose that
+ you have activated help mode, and you pressed
+ keypad 3. Speakup
+ says: "keypad 3 is character, say next."
+ The message "character, say next" names a Speakup function, and
+ it comes from this function_names file.
+
+What: /sys/accessibility/speakup/i18n/states
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This file contains names for key states.
+ Again, these are part of the help system. For instance, if you
+ had pressed speakup + keypad 3, you would hear:
+ "speakup keypad 3 is go to bottom edge."
+ The speakup key is depressed, so the name of the key state is
+ speakup.
+ This part of the message comes from the states collection.
+
+What: /sys/accessibility/speakup/i18n/characters
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Through this sys entry, Speakup gives you the ability to change
+ how Speakup pronounces a given character. You could, for
+ example, change how some punctuation characters are spoken. You
+ can even change how Speakup will pronounce certain letters. For
+ further details see '12. Changing the Pronunciation of
+ Characters' in Speakup User's Guide (file spkguide.txt in
+ source).
+
+What: /sys/accessibility/speakup/i18n/colors
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: When you use the "say attributes" function, Speakup says the
+ name of the foreground and background colors. These names come
+ from the i18n/colors file.
+
+What: /sys/accessibility/speakup/i18n/formatted
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This group of messages contains embedded formatting codes, to
+ specify the type and width of displayed data. If you change
+ these, you must preserve all of the formatting codes, and they
+ must appear in the order used by the default messages.
+
+What: /sys/accessibility/speakup/i18n/key_names
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Again, key_names is used by Speakup's help system. In the
+ previous example, Speakup said that you pressed "keypad 3."
+ This name came from the key_names file.
+
+What: /sys/accessibility/speakup/<synth-name>/
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: In `/sys/accessibility/speakup` is a directory corresponding to
+ the synthesizer driver currently in use (E.G) `soft` for the
+ soft driver. This directory contains files which control the
+ speech synthesizer itself,
+ as opposed to controlling the speakup
+ screen reader. The parameters in this directory have the same
+ names and functions across all
+ supported synthesizers. The range
+ of values for freq, pitch, rate, and vol is the same for all
+ supported synthesizers, with the given range being internally
+ mapped by the driver to more or less fit the range of values
+ supported for a given parameter by the individual synthesizer.
+ Below is a description of values and parameters for soft
+ synthesizer, which is currently the most commonly used.
+
+What: /sys/accessibility/speakup/soft/caps_start
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This is the string that is sent to the synthesizer to cause it
+ to start speaking uppercase letters. For the soft synthesizer
+ and most others, this causes the pitch of the voice to rise
+ above the currently set pitch.
+
+What: /sys/accessibility/speakup/soft/caps_stop
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This is the string sent to the synthesizer to cause it to stop
+ speaking uppercase letters. In the case of the soft synthesizer
+ and most others, this returns the pitch of the voice
+ down to the
+ currently set pitch.
+
+What: /sys/accessibility/speakup/soft/delay_time

+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the frequency of the speech synthesizer. Range is

+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This controls how many jiffys the kernel gives to the

+ or even crash it.
+
+What: /sys/accessibility/speakup/soft/pitch
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the pitch of the synthesizer. The range is 0-9.
+
+What: /sys/accessibility/speakup/soft/punct
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the amount of punctuation spoken by the
+ synthesizer. The range for the soft driver seems to be 0-2.

+
+What: /sys/accessibility/speakup/soft/rate
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org

+What: /sys/accessibility/speakup/soft/voice
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the voice used by the synthesizer if the
