[PATCH V2 OLK-5.10 0/6] Make the rcache depot scale better
by Zhang Zekun 10 Dec '23

10 Dec '23

Recently we have meet a problem when running FIO test. In our kunpeng server with 320 cores, about 80% cpus comes to- 100% usage, and soft lockup appears in the kernel message, which shows it stuck in __alloc_and_insert_iova_range(). Both the call trace and high cpu occupy rate implys that the iova_rcache behaves poorly to alloc iovas. A similar problem has been addressed in early months this year, the solution is just to enlarge the MAX_GLOBAL_MAGS to 128, but it requires to growth with the cpu cores, and it is hard to set a accurate val for a specific machine. So, it is better to use solutions from the linux community, use a list to replace the array of iova_rcache->depot. It will push iova_magazine to depot list when the local cpu_rcache is full, and use schedul_delayed_work() to free it after 100ms. The minimum length of the depot list is the num of online_cpus(). The performance of this patch shows good. This patch set use a lot of timers to record the iova_magazine, and the delay of timers in system may increase when undering heavy work load, but it should not cause problem as timers itself allows a inaccurate delay for a range. v2: - change a comment in patch 5/6, no code change. We need to merge "iommu/iova: change IOVA_MAG_SIZE to 127 to save memory" first to resolve a compile error: error: static assertion failed: "!(sizeof(struct iova_magazine) & (sizeof(struct iova_magazine) - 1))" Feng Tang (1): iommu/iova: change IOVA_MAG_SIZE to 127 to save memory Zhang Zekun (5): Revert "iommu/iova: move IOVA_MAX_GLOBAL_MAGS outside of IOMMU_SUPPORT" Revert "config: enable set the max iova mag size to 128" Revert "iommu/iova: increase the iova_rcache depot max size to 128" iommu/iova: Make the rcache depot scale better iommu/iova: Manage the depot list size arch/arm64/configs/openeuler_defconfig | 1 - drivers/iommu/Kconfig | 10 ---- drivers/iommu/iova.c | 80 +++++++++++++++++++------- include/linux/iova.h | 7 ++- 4 files changed, 64 insertions(+), 34 deletions(-) -- 2.17.1

[PATCH OLK-5.10] iommu/arm-smmu-v3: Add a SYNC command to avoid broken page table prefetch
by Zhang Zekun 10 Dec '23

10 Dec '23

hulk inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8MVBZ CVE: NA ----------------------------------------------- On Hisilicon LINXICORE9100 cores, SMMU pagetable prefetch features may prefetch and use a invalid PTE even the PTE is valid at that time. This will cause the device trigger fake pagefaults. If the SMMU works in terminate mode, transactions which occur fake pagefaults will be aborted, and could result in unexpected errors. To fix this problem, we need to add a SYNC command after smmu has map a iova, then smmu will always try to get the newest PTE.

[PATCH OLK-5.10] smart_grid: cpufreq: clear offline and isolated CPU in warm CPUs
by Yipeng Zou 09 Dec '23

09 Dec '23

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8MFO6 CVE: NA ---------------------------------------- When there has some CPU has been offline or isolated, the warm zone CPUs will not clear these CPUs. Because of the warm zone were saluted by a complement of hot zone. So, we need to clear offline and isolated CPUs in every time's warm zone CPUs update.

[PATCH OLK-6.6 v2] kasan: fix the compilation error for memcpy_mcs()
by Tong Tiangen 09 Dec '23

09 Dec '23

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8MWHA CVE: NA -------------------------------- check_memory_region() has been renamed kasan_check_range() in commit f00748bfa024 ("kasan: prefix global functions with kasan_"). Therefore, a compilation error occurs when check_memory_region() is called in memcpy_mcs() in file mm/kasan/shadow.c, this patch fix this issue.
