This patch adds support for kdump. In kdump case the normal kernel will reserve a region for the crash kernel and jump there on panic. Arch-specific functions are added to allow for implementing a crash dump file interface, /proc/vmcore, which can be viewed as a ELF file. A user-space tool, such as kexec-tools, is responsible for allocating a separate region for the core's ELF header within the crash kdump kernel memory and filling it in when executing kexec_load(). Then, its location will be advertised to the crash dump kernel via a command line argument "elfcorehdr=", and the crash dump kernel will preserve this region for later use with arch_reserve_vmcore() at boot time. At the same time, the crash kdump kernel is also limited within the "crashkernel" area via a command line argument "mem=", so as not to destroy the original kernel dump data. In the crash dump kernel environment, /proc/vmcore is used to access the primary kernel's memory with copy_oldmem_page(). I tested kdump on LoongArch machines (Loongson-3A5000) and it works as expected (suggested crashkernel parameter is "crashkernel=512M@2560M"), you may test it by triggering a crash through /proc/sysrq-trigger: $ sudo kexec -p /boot/vmlinux-kdump --reuse-cmdline --append="nr_cpus=1" # echo c > /proc/sysrq-trigger Signed-off-by:

Inspired by commit 9fb7410f ("arm64/BUG: Use BRK instruction for generic BUG traps"), do similar for LoongArch to use generic BUG() handler. This patch uses the BREAK software breakpoint instruction to generate a trap instead, similarly to most other arches, with the generic BUG code generating the dmesg boilerplate. This allows bug metadata to be moved to a separate table and reduces the amount of inline code at BUG() and WARN() sites. This also avoids clobbering any registers before they can be dumped. To mitigate the size of the bug table further, this patch makes use of the existing infrastructure for encoding addresses within the bug table as 32-bit relative pointers instead of absolute pointers. (Note: this limits the max kernel size to 2GB.)

We can support more cache attributes (e.g., CC, SUC and WUC) and page protection when we use TLB for ioremap(). The implementation is based on GENERIC_IOREMAP. The existing simple ioremap() implementation has better performance so we keep it and introduce ARCH_IOREMAP to control the selection. We move pagetable_init() earlier to make early ioremap() works, and we modify the PCI ecam mapping because the TLB-based version of ioremap() will actually take the size into account. Signed-off-by:

Current cache probe and flush methods have some drawbacks: 1, Assume there are 3 cache levels and only 3 levels; 2, Assume L1 = I + D, L2 = V, L3 = S, V is exclusive, S is inclusive. However, the fact is I + D, I + D + V, I + D + S and I + D + V + S are all valid. So, refactor the cache probe and flush methods to adapt more types of cache hierarchy. Signed-off-by:

This patch simplifies TLB load, store and modify exception handlers: 1. Reduce instructions, such as alu/csr and memory access; 2. Execute tlb search instruction only in the fast path; 3. Return directly from the fast path for both normal and huge pages; 4. Re-tab the assembly for better vertical alignment. And fixes the concurrent modification issue of fast path for huge pages. This issue will occur in the following steps: CPU-1 (In TLB exception) CPU-2 (In THP splitting) 1: Load PMD entry (HUGE=1) 2: Goto huge path 3: Store PMD entry (HUGE=0) 4: Reload PMD entry (HUGE=0) 5: Fill TLB entry (PA is incorrect) This patch also slightly improves the TLB processing performance: * Normal pages: 2.15%, Huge pages: 1.70%. #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <sys/mman.h> int main(int argc, char *argv[]) { size_t page_size; size_t mem_size; size_t off; void *base; int flags; int i; if (argc < 2) { fprintf(stderr, "%s MEM_SIZE [HUGE]\n", argv[0]); return -1; } page_size = sysconf(_SC_PAGESIZE); flags = MAP_PRIVATE | MAP_ANONYMOUS; mem_size = strtoul(argv[1], NULL, 10); if (argc > 2) flags |= MAP_HUGETLB; for (i = 0; i < 10; i++) { base = mmap(NULL, mem_size, PROT_READ, flags, -1, 0); if (base == MAP_FAILED) { fprintf(stderr, "Map memory failed!\n"); return -1; } for (off = 0; off < mem_size; off += page_size) *(volatile int *)(base + off); munmap(base, mem_size); } return 0; } Signed-off-by:

GCC >= 13 and GNU assembler >= 2.40 use these relocations to address external symbols, so we need to add them. Let the module loader emit GOT entries for data symbols so we would be able to handle GOT relocations. The GOT entry is just the data's symbol address. In module.lds, emit a stub .got section for a section header entry. The actual content of the section entry will be filled at runtime by module_ frob_arch_sections(). Tested-by:

If explicit relocation hints are used by the toolchain, -Wa,-mla-* options will be useless for the C code. So only use them for the !CONFIG_AS_HAS_EXPLICIT_RELOCS case. Replace "la" with "la.pcrel" in head.S to keep the semantic consistent with new and old toolchains for the low level startup code. For per-CPU variables, the "address" of the symbol is actually an offset from $r21. The value is near the loading address of main kernel image, but far from the loading address of modules. So we use model("extreme") attibute to tell the compiler that a PC-relative addressing with 32-bit offset is not sufficient for local per-CPU variables. The behavior with different assemblers and compilers are summarized in the following table: AS has CC has explicit relocs explicit relocs * Behavior ============================================================== No No Use la.* macros. No change from Linux 6.0. -------------------------------------------------------------- No Yes Disable explicit relocs. No change from Linux 6.0. -------------------------------------------------------------- Yes No Not supported. -------------------------------------------------------------- Yes Yes Enable explicit relocs. No -Wa,-mla* options used. ============================================================== *: We assume CC must have model attribute if it has explicit relocs. Both features are added in GCC 13 development cycle, so any GCC release >= 13 should be OK. Using early GCC 13 development snapshots may produce modules with unsupported relocations.

Commit ac7c3e4f ("compiler: enable CONFIG_OPTIMIZE_INLINING forcibly") allows compiler to uninline functions marked as 'inline'. In case of __xchg()/__cmpxchg() this would cause to reference BUILD_BUG(), which is an error case for catching bugs and will not happen for correct code, if __xchg()/__cmpxchg() is inlined. This bug can be produced with CONFIG_DEBUG_SECTION_MISMATCH enabled, and the solution is similar to below commits: 46f16195 ("MIPS: include: Mark __xchg as __always_inline"), 88356d09 ("MIPS: include: Mark __cmpxchg as __always_inline").

Pull clk driver fixes from Stephen Boyd: "Here's the last batch of clk driver fixes for this release. These patches fix serious problems, for example, i.MX has an issue where changing the NAND clk frequency hangs the system. On Allwinner H6 the GPU is being overclocked which could lead to long term hardware damage. And finally on some Broadcom SoCs the serial console stopped working because the clk tree hierarchy description got broken by an inadvertant DT node name change. That's fixed by using 'clock-output-names' to generate a stable and unique name for clks so the framework can properly link things up. There's also a couple build fixes in here. One to fix CONFIG_OF=n builds and one to avoid an array out of bounds bug that happens during clk registration on microchip. I hope that KASAN would have found that OOB problem, but probably KASAN wasn't attempted. Instead LLVM/clang compilation caused an oops, while GCC didn't" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: clk: imx93: drop of_match_ptr clk: iproc: Do not rely on node name for correct PLL setup clk: sunxi-ng: h6: Fix default PLL GPU rate clk: imx: imx6sx: remove the SET_RATE_PARENT flag for QSPI clocks clk: microchip: mpfs: make the rtc's ahb clock critical clk: microchip: mpfs: fix clk_cfg array bounds violation clk: ingenic-tcu: Properly enable registers before accessing timers

Merge tag 'perf-tools-fixes-for-v6.0-2022-09-29' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux Pull perf tools fixes from Arnaldo Carvalho de Melo: - Fail the 'perf test record' entry on error, fixing a regression where just setup stuff like allocating memory and not the actual things being tested failed. - Fixup disabling of -Wdeprecated-declarations for the python scripting engine, the previous attempt had a brown paper bag thinko. - Fix branch stack sampling test to include sanity check for branch filter on PowerPC. - Update is_ignored_symbol function to match the kernel ignored list, fixing running the 'perf test' entry that compares resolving symbols from kallsyms to resolving from vmlinux. - Augment the data source type with ARM's neoverse_spe list, the previous code was limited in its search resolving the data source. - Fix some clang 5 variable set but unused cases. - Get a perf cgroup more portably in BPF as the __builtin_preserve_enum_value builtin is not available in older versions of clang. In those cases we can forgo BPF's CO-RE (Compile Once, Run Everywhere). - More Fixes for Intel's hybrid CPU model. * tag 'perf-tools-fixes-for-v6.0-2022-09-29' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: perf build: Fixup disabling of -Wdeprecated-declarations for the python scripting engine perf tests mmap-basic: Remove unused variable to address clang 15 warning perf parse-events: Ignore clang 15 warning about variable set but unused in bison produced code perf tests record: Fail the test if the 'errs' counter is not zero perf test: Fix test case 87 ("perf record tests") for hybrid systems perf arm-spe: augment the data source type with neoverse_spe list perf tests vmlinux-kallsyms: Update is_ignored_symbol function to match the kernel ignored list perf tests powerpc: Fix branch stack sampling test to include sanity check for branch filter perf parse-events: Remove "not supported" hybrid cache events perf print-events: Fix "perf list" can not display the PMU prefix for some hybrid cache events perf tools: Get a perf cgroup more portably in BPF
