* drivers/firmware: Make efi/esrt.c driver explicitly non-modularPaul Gortmaker2015-10-121-16/+3
| | | | | | | | | | | | | | | | | | | | | | | The Kconfig for this driver is currently hidden with: config EFI_ESRT bool ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. We leave some tags like MODULE_AUTHOR for documentation purposes. We don't replace module.h with init.h since the file already has that.

* efi: Use the generic efi.memmap instead of 'memmap'Matt Fleming2015-10-111-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Guenter reports that commit: 7bf793115dd9 ("efi, x86: Rearrange efi_mem_attributes()") breaks the IA64 compilation with the following error: drivers/built-in.o: In function `efi_mem_attributes': (.text+0xde962): undefined reference to `memmap' Instead of using the (rather poorly named) global variable 'memmap' which doesn't exist on IA64, use efi.memmap which points to the 'memmap' object on x86 and arm64 and which is NULL for IA64. The fact that efi.memmap is NULL for IA64 is OK because IA64 provides its own implementation of efi_mem_attributes().

* acpi/apei: Use appropriate pgprot_t to map GHES memoryJonathan (Zhixiong) Zhang2015-09-141-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the ACPI APEI firmware handles hardware error first (called "firmware first handling"), the firmware updates the GHES memory region with hardware error record (called "generic hardware error record"). Essentially the firmware writes hardware error records in the GHES memory region, triggers an NMI/interrupt, then the GHES driver goes off and grabs the error record from the GHES region. The kernel currently maps the GHES memory region as cacheable (PAGE_KERNEL) for all architectures. However, on some arm64 platforms, there is a mismatch between how the kernel maps the GHES region (PAGE_KERNEL) and how the firmware maps it (EFI_MEMORY_UC, ie. uncacheable), leading to the possibility of the kernel GHES driver reading stale data from the cache when it receives the interrupt. With stale data being read, the kernel is unaware there is new hardware error to be handled when there actually is; this may lead to further damage in various scenarios, such as error propagation caused data corruption. If uncorrected error (such as double bit ECC error) happened in memory operation and if the kernel is unaware of such an event happening, errorneous data may be propagated to the disk. Instead GHES memory region should be mapped with page protection type according to what is returned from arch_apei_get_mem_attribute().

On x86, we currently have no way to look up the EFI memory map attributes for a region in a consistent way, because the memmap is discarded after efi_free_boot_services(). So if you call efi_mem_attributes() during boot and at runtime, you could theoretically see different attributes. Since we are yet to see any x86 platforms that require anything other than PAGE_KERNEL (some arm64 platforms require the equivalent of PAGE_KERNEL_NOCACHE), return that until we know differently.

| | | | | | | | | | | | | | | | | | | | | | | | | | x86 and ia64 implement efi_mem_attributes() differently. This function needs to be available for other architectures (such as arm64) as well, such as for the purpose of ACPI/APEI. ia64 EFI does not set up a 'memmap' variable and does not set the EFI_MEMMAP flag, so it needs to have its unique implementation of efi_mem_attributes(). Move efi_mem_attributes() implementation from x86 to the core EFI code, and declare it with __weak. It is recommended that other architectures should not override the default implementation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit: aeffc4928ea2 ("x86/efi: Request desired alignment via the PE/COFF headers") Linn reports that Signtool complains that kernels built with CONFIG_EFI_STUB=y are violating the PE/COFF specification because the 'SizeOfImage' field is not a multiple of 'SectionAlignment'. This violation was introduced as an optimisation to skip having the kernel relocate itself during boot and instead have the firmware place it at a correctly aligned address. No one else has complained and I'm not aware of any firmware implementations that refuse to boot with commit aeffc4928ea2, but it's a real bug, so revert the offending commit.

* x86/efi-bgrt: Switch pr_err() to pr_debug() for invalid BGRTMatt Fleming2015-08-081-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | It's totally legitimate, per the ACPI spec, for the firmware to set the BGRT 'status' field to zero to indicate that the BGRT image isn't being displayed, and we shouldn't be printing an error message in that case because it's just noise for users. So swap pr_err() for pr_debug(). However, Josh points that out it still makes sense to test the validity of the upper 7 bits of the 'status' field, since they're marked as "reserved" in the spec and must be zero. If firmware violates this it really *is* an error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | exponential backoff This is to workaround the llock/scond livelock HS38x4 could get into a LLOCK/SCOND livelock in case of multiple overlapping coherency transactions in the SCU. The exclusive line state keeps rotating among contenting cores leading to a never ending cycle. So break the cycle by deferring the retry of failed exclusive access (SCOND). The actual delay needed is function of number of contending cores as well as the unrelated coherency traffic from other cores. To keep the code simple, start off with small delay of 1 which would suffice most cases and in case of contention double the delay. Eventually the delay is sufficient such that the coherency pipeline is drained, thus a subsequent exclusive access would succeed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | With LLOCK/SCOND, the rwlock counter can be atomically updated w/o need for a guarding spin lock. This in turn elides the EXchange instruction based spinning which causes the cacheline transition to exclusive state and concurrent spinning across cores would cause the line to keep bouncing around. LLOCK/SCOND based implementation is superior as spinning on LLOCK keeps the cacheline in shared state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current spin_lock uses EXchange instruction to implement the atomic test and set of lock location (reads orig value and ST 1). This however forces the cacheline into exclusive state (because of the ST) and concurrent loops in multiple cores will bounce the line around between cores. Instead, use LLOCK/SCOND to implement the atomic test and set which is better as line is in shared state while lock is spinning on LLOCK The real motivation of this change however is to make way for future changes in atomics to implement delayed retry (with backoff). Initial experiment with delayed retry in atomics combined with orig EX based spinlock was a total disaster (broke even LMBench) as struct sock has a cache line sharing an atomic_t and spinlock. The tight spinning on lock, caused the atomic retry to keep backing off such that it would never finish.

This combined revert is done to eliminate the possibility of a partial revert in stable@ kernels. In hindsight the correct fix, at the time 1c220c69 was applied to fix the regression that 148e51ba introduced, should've been to simply revert 148e51ba.

This patch extends support for the other TLV types so they can be easily added at a later stage. TLV structure is moved to common topology control header since it's a common field for controls and can be processed in a general way. Users must set a proper access flag for a control since it's used to decide if the TLV field is valid and if a TLV callback is needed. Removed the following fields from topology TLV struct: - size/count: type can decide the size. - numid: not needed to initialize TLV for kcontrol. - data: replaced by the type specific struct. Added TLV structure to generic control header and removed TLV structure from mixer control.

This chip includes ARM7 core, and loads and runs program. The firmware is stored in on-board memory and loaded every powering-on from it. Echo Audio ships several versions of firmwares for each model. These firmwares have each quirk and the quirk changes a sequence of packets. As long as I investigated, AudioFire2/AudioFire4/AudioFirePre8 have a quirk to transfer a first packet with 0x02 in its dbc field. This causes ALSA Fireworks driver to detect discontinuity. In this case, firmware version 5.7.0, 5.7.3 and 5.8.0 are used.

Thus, this quirk may be observed among them. This commit adds a new member for AMDTP structure. This member represents the value of dbc field in a first AMDTP packet. Drivers can set it with a preferred value according to model's quirk.
