2024-05-10kbuild: use $(src) instead of $(srctree)/$(src) for source directoryMasahiro Yamada1-5/+0
Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for checked-in source files. It is merely a convention without any functional difference. In fact, $(obj) and $(src) are exactly the same, as defined in scripts/Makefile.build: src := $(obj) When the kernel is built in a separate output directory, $(src) does not accurately reflect the source directory location. While Kbuild resolves this discrepancy by specifying VPATH=$(srctree) to search for source files, it does not cover all cases. For example, when adding a header search path for local headers, -I$(srctree)/$(src) is typically passed to the compiler. This introduces inconsistency between upstream and downstream Makefiles because $(src) is used instead of $(srctree)/$(src) for the latter. To address this inconsistency, this commit changes the semantics of $(src) so that it always points to the directory in the source tree. Going forward, the variables used in Makefiles will have the following meanings: $(obj) - directory in the object tree $(src) - directory in the source tree (changed by this commit) $(objtree) - the top of the kernel object tree $(srctree) - the top of the kernel source tree Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced with $(src).

2024-03-07Revert "leds: Only descend into leds directory when CONFIG_NEW_LEDS is set"Duje Mihanović1-1/+1
This reverts commit b1ae40a5db6191c42e2e45d726407096f030ee08. The ExpressWire library introduced in commit 25ae5f5f4168 ("leds: Introduce ExpressWire library") does not depend on NEW_LEDS, but without this revert it would never get compiled if NEW_LEDS is not enabled. Revert this commit to allow the library to be compiled.

2024-01-12fbdev/intelfb: Remove driverThomas Zimmermann1-2/+1
From looking at the PCI IDs, every device supported by intelfb is also supported by i915. Anyone still using intelfb should please move on to i915, which does everything intelfb does but better. Removing intelfb is motivated by the driver's excessive use of the global screen_info state. The state belongs to architecture and firmware code; device drivers should not attempt to access it. But fixing intelfb would require a significant change in the driver's probing logic. As intelfb has been obsolete for nearly 2 decades, it is probably not worth the effort. Let's just remove it. Also remove the related documentation. Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Maik Broemme <mbroemme@libmpq.org> Signed-off-by: Helge Deller <deller@gmx.de>

It has been pointed out that naming a subsystem "genpd" isn't very self-explanatory and the acronym itself that means Generic PM Domain, is known only by a limited group of people.

2023-09-08Merge patch series "Add non-coherent DMA support for AX45MP"Palmer Dabbelt1-0/+1
Prabhakar <prabhakar.csengg@gmail.com> says: From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> non-coherent DMA support for AX45MP ==================================== On the Andes AX45MP core, cache coherency is a specification option so it may not be supported. In this case DMA will fail. To get around with this issue this patch series does the below: 1] Andes alternative ports is implemented as errata which checks if the IOCP is missing and only then applies to CMO errata. One vendor specific SBI EXT (ANDES_SBI_EXT_IOCP_SW_WORKAROUND) is implemented as part of errata. Below are the configs which Andes port provides (and are selected by RZ/Five): - ERRATA_ANDES - ERRATA_ANDES_CMO OpenSBI patch supporting ANDES_SBI_EXT_IOCP_SW_WORKAROUND SBI is now part v1.3 release. 2] Andes AX45MP core has a Programmable Physical Memory Attributes (PMA) block that allows dynamic adjustment of memory attributes in the runtime. It contains a configurable amount of PMA entries implemented as CSR registers to control the attributes of memory locations in interest. OpenSBI configures the PMA regions as required and creates a reserve memory node and propagates it to the higher boot stack. Currently OpenSBI (upstream) configures the required PMA region and passes this a shared DMA pool to Linux. reserved-memory { #address-cells = <2>; #size-cells = <2>; ranges; pma_resv0@58000000 { compatible = "shared-dma-pool"; reg = <0x0 0x58000000 0x0 0x08000000>; no-map; linux,dma-default; }; }; The above shared DMA pool gets appended to Linux DTB so the DMA memory requests go through this region. 3] We provide callbacks to synchronize specific content between memory and cache. 4] RZ/Five SoC selects the below configs - AX45MP_L2_CACHE - DMA_GLOBAL_POOL - ERRATA_ANDES - ERRATA_ANDES_CMO ----------x---------------------x--------------------x---------------x---- * b4-shazam-merge: soc: renesas: Kconfig: Select the required configs for RZ/Five SoC cache: Add L2 cache management for Andes AX45MP RISC-V core dt-bindings: cache: andestech,ax45mp-cache: Add DT binding documentation for L2 cache controller riscv: mm: dma-noncoherent: nonstandard cache operations support riscv: errata: Add Andes alternative ports riscv: asm: vendorid_list: Add Andes Technology to the vendors list Link: https://lore.kernel.org/r/20230818135723.80612-1-prabhakar.mahadev-lad.rj@bp.renesas.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
2023-09-01cache: Add L2 cache management for Andes AX45MP RISC-V coreLad Prabhakar1-0/+1
I/O Coherence Port (IOCP) provides an AXI interface for connecting external non-caching masters, such as DMA controllers. The accesses from IOCP are coherent with D-Caches and L2 Cache. IOCP is a specification option and is disabled on the Renesas RZ/Five SoC due to this reason IP blocks using DMA will fail. The Andes AX45MP core has a Programmable Physical Memory Attributes (PMA) block that allows dynamic adjustment of memory attributes in the runtime. It contains a configurable amount of PMA entries implemented as CSR registers to control the attributes of memory locations in interest. Below are the memory attributes supported: * Device, Non-bufferable * Device, bufferable * Memory, Non-cacheable, Non-bufferable * Memory, Non-cacheable, Bufferable * Memory, Write-back, No-allocate * Memory, Write-back, Read-allocate * Memory, Write-back, Write-allocate * Memory, Write-back, Read and Write-allocate More info about PMA (section 10.3): Link: http://www.andestech.com/wp-content/uploads/AX45MP-1C-Rev.-5.0.0-Datasheet.pdf As a workaround for SoCs with IOCP disabled CMO needs to be handled by software. Firstly OpenSBI configures the memory region as "Memory, Non-cacheable, Bufferable" and passes this region as a global shared dma pool as a DT node. With DMA_GLOBAL_POOL enabled all DMA allocations happen from this region and synchronization callbacks are implemented to synchronize when doing DMA transactions. Example PMA region passes as a DT node from OpenSBI: reserved-memory { #address-cells = <2>; #size-cells = <2>; ranges; pma_resv0@58000000 { compatible = "shared-dma-pool"; reg = <0x0 0x58000000 0x0 0x08000000>; no-map; linux,dma-default; }; }; Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> Reviewed-by: Conor Dooley <conor.dooley@microchip.com> Tested-by: Conor Dooley <conor.dooley@microchip.com> # tyre-kicking on a d1 Link: https://lore.kernel.org/r/20230818135723.80612-6-prabhakar.mahadev-lad.rj@bp.renesas.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>

2023-07-11genpd: Create a new subsystem directory to host genpd providersUlf Hansson1-0/+1
There are currently ~60 users of the genpd provider interface, which implementations are sprinkled across various subsystems. To simplify with maintenance let's create a new subsystem (drivers/genpd) and start moving the providers in there. My intention is also to host a git tree to collect and to get the patches tested/integrated through the linux-next tree. Ideally this should release some of the burden on the soc maintainers. Note that, I will of course require acks/reviews from the current platform maintainers, hence the MAINTAINERS file needs to be updated accordingly for each genpd provider that is moved into the new genpd subsystem.

Pull Compute Express Link (CXL) updates from Dan Williams: "To date Linux has been dependent on platform-firmware to map CXL RAM regions and handle events / errors from devices. With this update we can now parse / update the CXL memory layout, and report events / errors from devices. This is a precursor for the CXL subsystem to handle the end-to-end "RAS" flow for CXL memory. i.e. the flow that for DDR-attached-DRAM is handled by the EDAC driver where it maps system physical address events to a field-replaceable-unit (FRU / endpoint device). In general, CXL has the potential to standardize what has historically been a pile of memory-controller-specific error handling logic. Another change of note is the default policy for handling RAM-backed device-dax instances. Previously the default access mode was "device", mmap(2) a device special file to access memory. The new default is "kmem" where the address range is assigned to the core-mm via add_memory_driver_managed(). This saves typical users from wondering why their platform memory is not visible via free(1) and stuck behind a device-file. At the same time it allows expert users to deploy policy to, for example, get dedicated access to high performance memory, or hide low performance memory from general purpose kernel allocations. This affects not only CXL, but also systems with high-bandwidth-memory that platform-firmware tags with the EFI_MEMORY_SP (special purpose) designation. Summary: - CXL RAM region enumeration: instantiate 'struct cxl_region' objects for platform firmware created memory regions - CXL RAM region provisioning: complement the existing PMEM region creation support with RAM region support - "Soft Reservation" policy change: Online (memory hot-add) soft-reserved memory (EFI_MEMORY_SP) by default, but still allow for setting aside such memory for dedicated access via device-dax. - CXL Events and Interrupts: Takeover CXL event handling from platform-firmware (ACPI calls this CXL Memory Error Reporting) and export CXL Events via Linux Trace Events. - Convey CXL _OSC results to drivers: Similar to PCI, let the CXL subsystem interrogate the result of CXL _OSC negotiation. - Emulate CXL DVSEC Range Registers as "decoders": Allow for first-generation devices that pre-date the definition of the CXL HDM Decoder Capability to translate the CXL DVSEC Range Registers into 'struct cxl_decoder' objects. - Set timestamp: Per spec, set the device timestamp in case of hotplug, or if platform-firwmare failed to set it. - General fixups: linux-next build issues, non-urgent fixes for pre-production hardware, unit test fixes, spelling and debug message improvements" * tag 'cxl-for-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (66 commits) dax/kmem: Fix leak of memory-hotplug resources cxl/mem: Add kdoc param for event log driver state cxl/trace: Add serial number to trace points cxl/trace: Add host output to trace points cxl/trace: Standardize device information output cxl/pci: Remove locked check for dvsec_range_allowed() cxl/hdm: Add emulation when HDM decoders are not committed cxl/hdm: Create emulated cxl_hdm for devices that do not have HDM decoders cxl/hdm: Emulate HDM decoder from DVSEC range registers cxl/pci: Refactor cxl_hdm_decode_init() cxl/port: Export cxl_dvsec_rr_decode() to cxl_port cxl/pci: Break out range register decoding from cxl_hdm_decode_init() cxl: add RAS status unmasking for CXL cxl: remove unnecessary calling of pci_enable_pcie_error_reporting() dax/hmem: build hmem device support as module if possible dax: cxl: add CXL_REGION dependency cxl: avoid returning uninitialized error code cxl/pmem: Fix nvdimm registration races cxl/mem: Fix UAPI command comment cxl/uapi: Tag commands from cxl_query_cmd() ...

2023-02-05kbuild: remove --include-dir MAKEFLAG from top MakefileMasahiro Yamada1-0/+5
I added $(srctree)/ to some included Makefiles in the following commits: - 3204a7fb98a3 ("kbuild: prefix $(srctree)/ to some included Makefiles") - d82856395505 ("kbuild: do not require sub-make for separate output tree builds") They were a preparation for removing --include-dir flag. I have never thought --include-dir useful. Rather, it _is_ harmful. For example, run the following commands: $ make -s ARCH=x86 mrproper defconfig $ make ARCH=arm O=foo dtbs make[1]: Entering directory '/tmp/linux/foo' HOSTCC scripts/basic/fixdep Error: kernelrelease not valid - run 'make prepare' to update it UPD include/config/kernel.release make[1]: Leaving directory '/tmp/linux/foo' The first command configures the source tree for x86. The next command tries to build ARM device trees in the separate foo/ directory - this must stop because the directory foo/ has not been configured yet. However, due to --include-dir=$(abs_srctree), the top Makefile includes the wrong include/config/auto.conf from the source tree and continues building. Kbuild traverses the directory tree, but of course it does not work correctly. The Error message is also pointless - 'make prepare' does not help at all for fixing the issue. This commit fixes more arch Makefile, and finally removes --include-dir from the top Makefile. There are more breakages under drivers/, but I do not volunteer to fix them all. I just moved --include-dir to drivers/Makefile. With this commit, the second command will stop with a sensible message. $ make -s ARCH=x86 mrproper defconfig $ make ARCH=arm O=foo dtbs make[1]: Entering directory '/tmp/linux/foo' SYNC include/config/auto.conf.cmd *** *** The source tree is not clean, please run 'make ARCH=arm mrproper' *** in /tmp/linux *** make[2]: *** [../Makefile:646: outputmakefile] Error 1 /tmp/linux/Makefile:770: include/config/auto.conf.cmd: No such file or directory make[1]: *** [/tmp/linux/Makefile:793: include/config/auto.conf.cmd] Error 2 make[1]: Leaving directory '/tmp/linux/foo' make: *** [Makefile:226: __sub-make] Error 2 Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2023-01-31ata: pata_parport: add driver (PARIDE replacement)Ondrej Zary1-1/+1
The pata_parport is a libata-based replacement of the old PARIDE subsystem - driver for parallel port IDE devices. It uses the original paride low-level protocol drivers but does not need the high-level drivers (pd, pcd, pf, pt, pg). The IDE devices behind parallel port adapters are handled by the ATA layer. This will allow paride and its high-level drivers to be removed. Unfortunately, libata drivers cannot sleep so pata_parport claims parport before activating the ata host and keeps it claimed (and protocol connected) until the ata host is removed. This means that no devices can be chained (neither other pata_parport devices nor a printer). paride and pata_parport are mutually exclusive because the compiled protocol drivers are incompatible. Tested with: - Imation SuperDisk LS-120 and HP C4381A (EPAT) - Freecom Parallel CD (FRPW) - Toshiba Mobile CD-RW 2793008 w/Freecom Parallel Cable rev.903 (FRIQ) - Backpack CD-RW 222011 and CD-RW 19350 (BPCK6) The following bugs in low-level protocol drivers were found and will be fixed later: Note: EPP-32 mode is buggy in EPAT - and also in all other protocol drivers - they don't handle non-multiple-of-4 block transfers correctly. This causes problems with LS-120 drive. There is also another bug in EPAT: EPP modes don't work unless a 4-bit or 8-bit mode is used first (probably some initialization missing?). Once the device is initialized, EPP works until power cycle. So after device power on, you have to: echo "parport0 epat 0" >/sys/bus/pata_parport/new_device echo pata_parport.0 >/sys/bus/pata_parport/delete_device echo "parport0 epat 4" >/sys/bus/pata_parport/new_device (autoprobe will initialize correctly as it tries the slowest modes first but you'll get the broken EPP-32 mode) Note: EPP modes are buggy in FRPW, only modes 0 and 1 work.

VPU stands for Versatile Processing Unit and it's a CPU-integrated inference accelerator for Computer Vision and Deep Learning applications. The VPU device consist of following components: - Buttress - provides CPU to VPU integration, interrupt, frequency and power management. - Memory Management Unit (based on ARM MMU-600) - translates VPU to host DMA addresses, isolates user workloads. - RISC based microcontroller - executes firmware that provides job execution API for the kernel-mode driver - Neural Compute Subsystem (NCS) - does the actual work, provides Compute and Copy engines. - Network on Chip (NoC) - network fabric connecting all the components This driver supports VPU IP v2.7 integrated into Intel Meteor Lake client CPUs (14th generation). Module sources are at drivers/accel/ivpu and module name is "intel_vpu.ko". This patch includes only very besic functionality: - module, PCI device and IRQ initialization - register definitions and low level register manipulation functions - SET/GET_PARAM ioctls - power up without firmware Co-developed-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20230117092723.60441-2-jacek.lawrynowicz@linux.intel.com
2022-11-15HID: Kconfig: split HID support and hid-core compilationBenjamin Tissoires1-1/+1
Currently, we step into drivers/hid/ based on the value of CONFIG_HID. However, that value is a tristate, meaning that it can be a module. As per the documentation, if we jump into the subdirectory by following an obj-m, we can not compile anything inside that subdirectory in vmlinux. It is considered as a bug. To make things more friendly to HID-BPF, split HID (the HID core parameter) from HID_SUPPORT (do we want any kind of HID support in the system?), and make this new config a boolean.

2022-06-10vme: move back to stagingArnd Bergmann1-1/+0
The VME subsystem graduated from staging into a top-level subsystem in 2012, with commit db3b9e990e75 ("Staging: VME: move VME drivers out of staging") stating: The VME device drivers have not moved out yet due to some API questions they are still working through, that should happen soon, hopefully. However, this never happened: maintenance of drivers/vme effectively stopped in 2017, with all subsequent changes being treewide cleanups. No hardware driver remains in staging, only the limited user-level access, and I just removed one of the two bridge drivers and the only remaining board. drivers/staging/vme/devices/ was recently moved to drivers/staging/vme_user/, but as the vme_user driver is the only one remaining for this subsystem, it is easier to just move the remaining three source files into this directory rather than keeping the original hierarchy.
