2021-12-16mips: kgdb: adjust the comment to the actual ifdef conditionLukas Bulwahn1-1/+1
The comment refers to CONFIG_CPU_32BIT, but the ifdef uses CONFIG_32BIT. As this ifdef and comment was introduced with initial mips-kgdb commit 8854700115ec ("[MIPS] kgdb: add arch support for the kernel's kgdb core"), it is probably just a minor issue that was overlooked during the patch creation and refactoring before submission. This inconsistency was identified with ./scripts/checkkconfigsymbols.py. This script has been quite useful to identify a number of bugs with Kconfig symbols and deserves to be executed and checked regularly. So, adjust the comment to the actual ifdef condition to reduce the reports made the script and simplify to use this script, as new issues are easier to spot when the list of reports is shorter.

2021-12-11futex: Fix additional regressionsArnd Bergmann1-3/+3
Naresh reported another architecture that was broken by the same typo that was already fixed for three architectures: mips also refers to the futex_atomic_op_inuser_local() function by the wrong name and runs into a missing closing '}' as well. Going through the source tree the same typo was found in the documentation as well as in the xtensa code, both of which ended up escaping the regression testing so far. In the case of xtensa, it appears that the broken code path is only used when building for platforms that are not supported by the default gcc configuration, so they are impossible to test for with default setups. After going through these more carefully and fixing up the typos, all architectures have been build-tested again to ensure that this is now complete.

2021-11-25futex: Ensure futex_atomic_cmpxchg_inatomic() is presentArnd Bergmann1-11/+18
The boot-time detection of futex_atomic_cmpxchg_inatomic() has a bug on some 32-bit arm builds, and Thomas Gleixner suggested that setting CONFIG_HAVE_FUTEX_CMPXCHG would avoid the problem, as it is always present anyway. Looking into which other architectures could do the same showed that almost all architectures have it, the exceptions being: - some old 32-bit MIPS uniprocessor cores without ll/sc - one xtensa variant with no SMP - 32-bit SPARC when built for SMP Fix MIPS And Xtensa by rearranging the generic code to let it be used as a fallback. For SPARC, the SMP definition just ends up turning off futex anyway, so this can be done at Kconfig time instead. Note that sparc32 glibc requires the CASA instruction for its mutexes anyway, which is only available when running on SPARCv9 or LEON CPUs, but needs to be implemented in the sparc32 kernel for those.

2021-11-17Add linux/cacheflush.hMatthew Wilcox (Oracle)1-2/+0
Many architectures do not include asm-generic/cacheflush.h, so turn the includes on their head and add linux/cacheflush.h which includes asm/cacheflush.h. Move the flush_dcache_folio() declaration from asm-generic/cacheflush.h to linux/cacheflush.h and change linux/highmem.h to include linux/cacheflush.h instead of asm/cacheflush.h so that all necessary places will see flush_dcache_folio(). More functions should have their default implementations moved in the future, but those are for follow-on patches. This fixes csky, sparc and sparc64 which were missed in the commit which added flush_dcache_folio().

After making the brcmstb_gisb driver modular with 707a4cdf86e5 ("bus: brcmstb_gisb: Allow building as module") Guenter reported that mips allmodconfig failed to link because board_be_handler was referenced. Thomas indicated that if we were to continue making the brcmstb_gisb driver modular for MIPS we would need to introduce a function that allows setting the board_be_handler and export that function towards modules. This is what is being done here: board_be_handler is made static and is now settable with a mips_set_be_handler() function which is exported.

mips_cm_error_report() extracts the cause and other cause from the error register using shifts. This works fine for the former, as it is stored in the top bits, and the shift will thus remove all non-related bits. However, the latter is stored in the bottom bits, hence thus needs masking to get rid of non-related bits. Without such masking, using it as an index into the cm2_causes[] array will lead to an out-of-bounds access, probably causing a crash. Fix this by using FIELD_GET() instead. Bite the bullet and convert all MIPS CM handling to the bitfield API, to improve readability and safety.

Pull memory folios from Matthew Wilcox: "Add memory folios, a new type to represent either order-0 pages or the head page of a compound page. This should be enough infrastructure to support filesystems converting from pages to folios. The point of all this churn is to allow filesystems and the page cache to manage memory in larger chunks than PAGE_SIZE. The original plan was to use compound pages like THP does, but I ran into problems with some functions expecting only a head page while others expect the precise page containing a particular byte. The folio type allows a function to declare that it's expecting only a head page. Almost incidentally, this allows us to remove various calls to VM_BUG_ON(PageTail(page)) and compound_head(). This converts just parts of the core MM and the page cache. For 5.17, we intend to convert various filesystems (XFS and AFS are ready; other filesystems may make it) and also convert more of the MM and page cache to folios. For 5.18, multi-page folios should be ready. The multi-page folios offer some improvement to some workloads. The 80% win is real, but appears to be an artificial benchmark (postgres startup, which isn't a serious workload). Real workloads (eg building the kernel, running postgres in a steady state, etc) seem to benefit between 0-10%. I haven't heard of any performance losses as a result of this series. Nobody has done any serious performance tuning; I imagine that tweaking the readahead algorithm could provide some more interesting wins. There are also other places where we could choose to create large folios and currently do not, such as writes that are larger than PAGE_SIZE.

2021-10-24MIPS: Fix assembly error from MIPSr2 code used within MIPS_ISA_ARCH_LEVELMaciej W. Rozycki1-1/+4
Fix assembly errors like: {standard input}: Assembler messages: {standard input}:287: Error: opcode not supported on this processor: mips3 (mips3) `dins $10,$7,32,32' {standard input}:680: Error: opcode not supported on this processor: mips3 (mips3) `dins $10,$7,32,32' {standard input}:1274: Error: opcode not supported on this processor: mips3 (mips3) `dins $12,$9,32,32' {standard input}:2175: Error: opcode not supported on this processor: mips3 (mips3) `dins $10,$7,32,32' make[1]: *** [scripts/Makefile.build:277: mm/highmem.o] Error 1 with code produced from `__cmpxchg64' for MIPS64r2 CPU configurations using CONFIG_32BIT and CONFIG_PHYS_ADDR_T_64BIT. This is due to MIPS_ISA_ARCH_LEVEL downgrading the assembly architecture to `r4000' i.e. MIPS III for MIPS64r2 configurations, while there is a block of code containing a DINS MIPS64r2 instruction conditionalized on MIPS_ISA_REV >= 2 within the scope of the downgrade. The assembly architecture override code pattern has been put there for LL/SC instructions, so that code compiles for configurations that select a processor to build for that does not support these instructions while still providing run-time support for processors that do, dynamically switched by non-constant `cpu_has_llsc'. It went in with linux-mips.org commit aac8aa7717a2 ("Enable a suitable ISA for the assembler around ll/sc so that code builds even for processors that don't support the instructions. Plus minor formatting fixes.") back in 2005. Fix the problem by wrapping these instructions along with the adjacent SYNC instructions only, following the practice established with commit cfd54de3b0e4 ("MIPS: Avoid move psuedo-instruction whilst using MIPS_ISA_LEVEL") and commit 378ed6f0e3c5 ("MIPS: Avoid using .set mips0 to restore ISA"). Strictly speaking the SYNC instructions do not have to be wrapped as they are only used as a Loongson3 erratum workaround, so they will be enabled in the assembler by default, but do this so as to keep code consistent with other places.

'CONFIG_PCI_DRIVERS_GENERIC' Some MIPS defconfigs that don't define 'CONFIG_PCI_DRIVERS_GENERIC' but define 'CONFIG_PCI_DRIVERS_LEGACY' or none of them, can fail when they are built since definition for 'pci_remap_iospace' is being done in include file 'arch/mips/include/asm/pci.h' and the specific function implemented in 'arch/mips/pci/pci-generic.c'.

2021-09-21MIPS: ralink: don't define PC_IOBASE but increase IO_SPACE_LIMITSergio Paracuellos1-3/+1
Defining PCI_IOBASE results in pci resource handling working but the addresses generated for IO accesses are wrong since the ioremap in the pci core function 'pci_parse_request_of_pci_ranges' tries to remap to a fixed virtual address (PC_IOBASE) which can't work for KSEG1 addresses. To get it working this way, we would need to put PCI_IOBASE somewhere into KSEG2 which will result in creating TLB entries for IO addresses, which most of the time isn't needed on MIPS because of access via KSEG1. So avoid to define PCI_IOBASE and increase IO_SPACE_LIMIT resource for ralink MIPS platform instead, to get valid IO addresses for resources from pci core 'pci_address_to_pio' function.
