2023-11-22ACPI: Fix ARM32 platforms compile issue introduced by fw_table changesDave Jiang1-11/+11
Linus reported that: After commit a103f46633fd the kernel stopped compiling for several ARM32 platforms that I am building with a bare metal compiler. Bare metal compilers (arm-none-eabi-) don't define __linux__. This is because the header <acpi/platform/acenv.h> is now in the include path for <linux/irq.h>: CC arch/arm/kernel/irq.o CC kernel/sysctl.o CC crypto/api.o In file included from ../include/acpi/acpi.h:22, from ../include/linux/fw_table.h:29, from ../include/linux/acpi.h:18, from ../include/linux/irqchip.h:14, from ../arch/arm/kernel/irq.c:25: ../include/acpi/platform/acenv.h:218:2: error: #error Unknown target environment 218 | #error Unknown target environment | ^~~~~ The issue is caused by the introducing of splitting out the ACPI code to support the new generic fw_table code. Rafael suggested [1] moving the fw_table.h include in linux/acpi.h to below the linux/mutex.h. Remove the two includes in fw_table.h. Replace linux/fw_table.h include in fw_table.c with linux/acpi.h.

Pull CXL (Compute Express Link) updates from Dan Williams: "The main new functionality this time is work to allow Linux to natively handle CXL link protocol errors signalled via PCIe AER for current generation CXL platforms. This required some enlightenment of the PCIe AER core to workaround the fact that current generation RCH (Restricted CXL Host) platforms physically hide topology details and registers via a mechanism called RCRB (Root Complex Register Block). The next major highlight is reworks to address bugs in parsing region configurations for next generation VH (Virtual Host) topologies. The old broken algorithm is replaced with a simpler one that significantly increases the number of region configurations supported by Linux. This is again relevant for error handling so that forward and reverse address translation of memory errors can be carried out by Linux for memory regions instantiated by platform firmware. As for other cross-tree work, the ACPI table parsing code has been refactored for reuse parsing the "CDAT" structure which is an ACPI-like data structure that is reported by CXL devices. That work is in preparation for v6.8 support for CXL QoS. Think of this as dynamic generation of NUMA node topology information generated by Linux rather than platform firmware. Lastly, a number of internal object lifetime issues have been resolved along with misc. fixes and feature updates (decoders_committed sysfs ABI). Summary: - Add support for RCH (Restricted CXL Host) Error recovery - Fix several region assembly bugs - Fix mem-device lifetime issues relative to the sanitize command and RCH topology. - Refactor ACPI table parsing for CDAT parsing re-use in preparation for CXL QOS support" * tag 'cxl-for-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (50 commits) lib/fw_table: Remove acpi_parse_entries_array() export cxl/pci: Change CXL AER support check to use native AER cxl/hdm: Remove broken error path cxl/hdm: Fix && vs || bug acpi: Move common tables helper functions to common lib cxl: Add support for reading CXL switch CDAT table cxl: Add checksum verification to CDAT from CXL cxl: Export QTG ids from CFMWS to sysfs as qos_class attribute cxl: Add decoders_committed sysfs attribute to cxl_port cxl: Add cxl_decoders_committed() helper cxl/core/regs: Rework cxl_map_pmu_regs() to use map->dev for devm cxl/core/regs: Rename phys_addr in cxl_map_component_regs() PCI/AER: Unmask RCEC internal errors to enable RCH downstream port error handling PCI/AER: Forward RCH downstream port-detected errors to the CXL.mem dev handler cxl/pci: Disable root port interrupts in RCH mode cxl/pci: Add RCH downstream port error logging cxl/pci: Map RCH downstream AER registers for logging protocol errors cxl/pci: Update CXL error logging to use RAS register address PCI/AER: Refactor cper_print_aer() for use by CXL driver module cxl/pci: Add RCH downstream port AER register discovery ...

2023-10-28acpi: Move common tables helper functions to common libDave Jiang1-31/+11
Some of the routines in ACPI driver/acpi/tables.c can be shared with parsing CDAT. CDAT is a device-provided data structure that is formatted similar to a platform provided ACPI table. CDAT is used by CXL and can exist on platforms that do not use ACPI. Split out the common routine from ACPI to accommodate platforms that do not support ACPI and move that to /lib. The common routines can be built outside of ACPI if FIRMWARE_TABLES is selected.

2023-10-04cpuidle, ACPI: Evaluate LPI arch_flags for broadcast timerOza Pawandeep1-0/+9
Arm® Functional Fixed Hardware Specification defines LPI states, which provide an architectural context loss flags field that can be used to describe the context that might be lost when an LPI state is entered. - Core context Lost - General purpose registers. - Floating point and SIMD registers. - System registers, include the System register based - generic timer for the core. - Debug register in the core power domain. - PMU registers in the core power domain. - Trace register in the core power domain. - Trace context loss - GICR - GICD Qualcomm's custom CPUs preserves the architectural state, including keeping the power domain for local timers active. when core is power gated, the local timers are sufficient to wake the core up without needing broadcast timer. The patch fixes the evaluation of cpuidle arch_flags, and moves only to broadcast timer if core context lost is defined in ACPI LPI.

2023-09-11arch: Remove Itanium (IA-64) architectureArd Biesheuvel1-8/+1
The Itanium architecture is obsolete, and an informal survey [0] reveals that any residual use of Itanium hardware in production is mostly HP-UX or OpenVMS based. The use of Linux on Itanium appears to be limited to enthusiasts that occasionally boot a fresh Linux kernel to see whether things are still working as intended, and perhaps to churn out some distro packages that are rarely used in practice. None of the original companies behind Itanium still produce or support any hardware or software for the architecture, and it is listed as 'Orphaned' in the MAINTAINERS file, as apparently, none of the engineers that contributed on behalf of those companies (nor anyone else, for that matter) have been willing to support or maintain the architecture upstream or even be responsible for applying the odd fix. The Intel firmware team removed all IA-64 support from the Tianocore/EDK2 reference implementation of EFI in 2018. (Itanium is the original architecture for which EFI was developed, and the way Linux supports it deviates significantly from other architectures.) Some distros, such as Debian and Gentoo, still maintain [unofficial] ia64 ports, but many have dropped support years ago. While the argument is being made [1] that there is a 'for the common good' angle to being able to build and run existing projects such as the Grid Community Toolkit [2] on Itanium for interoperability testing, the fact remains that none of those projects are known to be deployed on Linux/ia64, and very few people actually have access to such a system in the first place. Even if there were ways imaginable in which Linux/ia64 could be put to good use today, what matters is whether anyone is actually doing that, and this does not appear to be the case. There are no emulators widely available, and so boot testing Itanium is generally infeasible for ordinary contributors. GCC still supports IA-64 but its compile farm [3] no longer has any IA-64 machines. GLIBC would like to get rid of IA-64 [4] too because it would permit some overdue code cleanups. In summary, the benefits to the ecosystem of having IA-64 be part of it are mostly theoretical, whereas the maintenance overhead of keeping it supported is real. So let's rip off the band aid, and remove the IA-64 arch code entirely. This follows the timeline proposed by the Debian/ia64 maintainer [5], which removes support in a controlled manner, leaving IA-64 in a known good state in the most recent LTS release. Other projects will follow once the kernel support is removed.

2023-06-15ACPI: Move ACPI_DEVICE_CLASS() to mod_devicetable.hAndy Shevchenko1-14/+0
The data type of struct acpi_device_id is defined in the mod_devicetable.h. It's suboptimal to require user with the almost agnostic code to include acpi.h solely for the macro that affects the data type defined elsewhere. Taking into account the above and for the sake of consistency move ACPI_DEVICE_CLASS() to mod_devicetable.h. Note, that with CONFIG_ACPI=n the ID table will be filed with data but it does not really matter because either it won't be used, or won't be compiled in some cases (when guarded by respective ifdeffery).

There's a lot of changes this development cycle, most of the work falls into two different categories: - fw_devlink fixes and updates. This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant. We didn't quite make it for this release, but the remaining patches will be finished up for the release after this one, but the groundwork has been laid for this effort.

2022-09-24LoongArch: Use acpi_arch_dma_setup() and remove ARCH_HAS_PHYS_TO_DMAJianmin Lv1-3/+6
Use _DMA defined in ACPI spec for translation between DMA address and CPU address, and implement acpi_arch_dma_setup for initializing dev->dma_range_map, where acpi_dma_get_range is called for parsing _DMA. e.g. If we have two dma ranges: cpu address dma address size offset 0x200080000000 0x2080000000 0x400000000 0x1fe000000000 0x400080000000 0x4080000000 0x400000000 0x3fc000000000 _DMA for pci devices should be declared in host bridge as flowing: Name (_DMA, ResourceTemplate() { QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, NonCacheable, ReadWrite, 0x0, 0x4080000000, 0x447fffffff, 0x3fc000000000, 0x400000000, , , ) QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, NonCacheable, ReadWrite, 0x0, 0x2080000000, 0x247fffffff, 0x1fe000000000, 0x400000000, , , ) }) Acked-by: Huacai Chen <chenhuacai@loongson.cn> Signed-off-by: Jianmin Lv <lvjianmin@loongson.cn> Signed-off-by: Rafael J.

2022-09-24ACPI: scan: Support multiple DMA windows with different offsetsJianmin Lv1-4/+3
In DT systems configurations, of_dma_get_range() returns struct bus_dma_region DMA regions; they are used to set-up devices DMA windows with different offset available for translation between DMA address and CPU address. In ACPI systems configuration, acpi_dma_get_range() does not return DMA regions yet and that precludes setting up the dev->dma_range_map pointer and therefore DMA regions with multiple offsets. Update acpi_dma_get_range() to return struct bus_dma_region DMA regions like of_dma_get_range() does. After updating acpi_dma_get_range(), acpi_arch_dma_setup() is changed for ARM64, where the original dma_addr and size are removed as these arguments are now redundant, and pass 0 and U64_MAX for dma_base and size of arch_setup_dma_ops; this is a simplification consistent with what other ACPI architectures also pass to iommu_setup_dma_ops().

On some platforms it is found that Linux more aggressively enters s2idle than Windows enters Modern Standby and this uncovers some synchronization issues for the platform. To aid in debugging this class of problems in the future, add support for an extra optional callback intended for drivers to emit extra debugging.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "As the diffstat shows, we've had lots of developments in a wide range at this time; the majority of changes are about ASoC, including subsystem-wide cleanups, continued SOF / Intel updates and a bunch of new drivers (as usual), while there have been some significant (but almost invisible) improvements in ALSA core side, too. Below are some highlights: Core: - Faster lookups of control elements with Xarray; normal user won't notice, but on the devices with tons of control elements, it can be visibly faster - Support for input validation for controls; this will harden for badly written drivers in general with a slight overhead - Deferred async signal handling for working around the potential deadlocks - Cleanup / refactoring raw MIDI locking code ASoC: - Restructing of the set_fmt() callbacks for making things clearer in situations like CODEC to CODEC links - Clean up and modernizing the DAI naming scheme setups - Merge of more of the Intel AVS driver stack, including some board integrations - New version 4 mechanism for communication with SOF DSPs - Suppoort for dynamically selecting the PLL to use at runtime on i.MX platforms - Improvements for CODEC to CODEC support in the generic cards - Support for AMD Jadeite and various machines, AMD RPL, Intel MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments TAS2780 HD- and USB-audio: - Continued improvement for CS35L41 (sub)codec support - More quirks for various devices (HP, Lenovo, Dell, Clevo)" * tag 'sound-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (778 commits) ALSA: hda/realtek: Add quirk for HP Spectre x360 15-eb0xxx ALSA: line6: Replace sprintf() with sysfs_emit() ALSA: hda: Replace sprintf() with sysfs_emit() ALSA: pcm: Replace sprintf() with sysfs_emit() ALSA: core: Replace scnprintf() with sysfs_emit() ALSA: control-led: Replace sprintf() with sysfs_emit() ALSA: aoa: Replace sprintf() with sysfs_emit() ALSA: ac97: Replace sprintf() with sysfs_emit() ALSA: hda/realtek: Add quirk for Clevo NV45PZ ALSA: hda/realtek: Add quirk for Lenovo Yoga9 14IAP7 ALSA: control: Use deferred fasync helper ALSA: pcm: Use deferred fasync helper ALSA: timer: Use deferred fasync helper ALSA: core: Add async signal helpers ASoC: q6asm: use kcalloc() instead of kzalloc() ACPI: scan: Add CLSA0101 Laptop Support ALSA: hda: cs35l41: Support CLSA0101 ALSA: hda: cs35l41: Use the CS35L41 HDA internal define ASoC: dt-bindings: use spi-peripheral-props.yaml ASoC: codecs: va-macro: use fsgen as clock ...
