2022-10-05PCI/ASPM: Correct LTR_L1.2_THRESHOLD computationBjorn Helgaas
80d7d7a904fa ("PCI/ASPM: Calculate LTR_L1.2_THRESHOLD from device characteristics") replaced a fixed value (163840ns) with one computed from T_POWER_OFF, Common_Mode_Restore_Time, etc., but it encoded the LTR_L1.2_THRESHOLD value incorrectly. This is especially a problem for small thresholds, e.g., 63ns fell into the "threshold_ns < 1024" case and was encoded as 32ns: LTR_L1.2_THRESHOLD_Scale = 1 (multiplier is 32ns) LTR_L1.2_THRESHOLD_Value = 63 >> 5 = 1 LTR_L1.2_THRESHOLD = multiplier * value = 32ns * 1 = 32ns Correct the algorithm to encode all times of 1023ns (0x3ff) or smaller exactly and larger times conservatively (the encoded threshold is never smaller than was requested). This reduces the chance of entering L1.2 when the device can't tolerate the exit latency.

2022-10-05PCI/ASPM: Ignore L1 PM Substates if device lacks capabilityBjorn Helgaas
187f91db8237 ("PCI/ASPM: Remove struct aspm_register_info.l1ss_cap") inadvertently removed a check for existence of the L1 PM Substates (L1SS) Capability before reading it. If there is no L1SS Capability, this means we mistakenly read PCI_COMMAND and PCI_STATUS (config address 0x04) and interpret that as the PCI_L1SS_CAP register, so we may incorrectly configure L1SS. Make sure the L1SS Capability exists before trying to read it.

This kernel module is used for testing. It's safe to say M here. It can also be built-in without X86_AMD_PSTATE enabled. Currently, only tests for amd-pstate are supported. If X86_AMD_PSTATE is set disabled, it can tell the users test can only run on amd-pstate driver, please set X86_AMD_PSTATE enabled. In the future, comparison tests will be added. It can set amd-pstate disabled and set acpi-cpufreq enabled to run test cases, then compare the test results.

2022-10-05nfsd: fix nfsd_file_unhash_and_disposeJeff Layton
nfsd_file_unhash_and_dispose() is called for two reasons: We're either shutting down and purging the filecache, or we've gotten a notification about a file delete, so we want to go ahead and unhash it so that it'll get cleaned up when we close. We're either walking the hashtable or doing a lookup in it and we don't take a reference in either case. What we want to do in both cases is to try and unhash the object and put it on the dispose list if that was successful. If it's no longer hashed, then we don't want to touch it, with the assumption being that something else is already cleaning up the sentinel reference. Instead of trying to selectively decrement the refcount in this function, just unhash it, and if that was successful, move it to the dispose list. Then, the disposal routine will just clean that up as usual. Also, just make this a void function, drop the WARN_ON_ONCE, and the comments about deadlocking since the nature of the purported deadlock is no longer clear.

When building with CONFIG_LTO after commit ba00c2a04fa5 ("arm64: fix the build with binutils 2.27"), the following build error occurs: In file included from arch/arm64/kernel/module-plts.c:6: In file included from include/linux/elf.h:6: In file included from arch/arm64/include/asm/elf.h:8: In file included from arch/arm64/include/asm/hwcap.h:9: In file included from arch/arm64/include/asm/cpufeature.h:9: In file included from arch/arm64/include/asm/alternative-macros.h:5: In file included from include/linux/bits.h:22: In file included from include/linux/build_bug.h:5: In file included from include/linux/compiler.h:248: In file included from arch/arm64/include/asm/rwonce.h:71: include/asm-generic/rwonce.h:67:9: error: expected string literal in 'asm' return __READ_ONCE(*(unsigned long *)addr); ^ arch/arm64/include/asm/rwonce.h:43:16: note: expanded from macro '__READ_ONCE' asm volatile(__LOAD_RCPC(b, %w0, %1) \ ^ arch/arm64/include/asm/rwonce.h:17:2: note: expanded from macro '__LOAD_RCPC' ALTERNATIVE( \ ^ Similar to the issue resolved by commit 0072dc1b53c3 ("arm64: avoid BUILD_BUG_ON() in alternative-macros"), there is a circular include dependency through <linux/bits.h> when CONFIG_LTO is enabled due to <asm/rwonce.h> appearing in the include chain before the contents of <asm/alternative-macros.h>, which results in ALTERNATIVE() not getting expanded properly because it has not been defined yet. Avoid this issue by including <vdso/bits.h>, which includes the definition of the BIT() macro, instead of <linux/bits.h>, as BIT() is the only macro from bits.h that is relevant to this header.
