[PATCH 5.15] swiotlb: max mapping size takes min align mask into account

by Rishabh Bhatnagar

From: Tianyu Lan <Tianyu.Lan(a)microsoft.com> commit 82806744fd7dde603b64c151eeddaa4ee62193fd upstream. swiotlb_find_slots() skips slots according to io tlb aligned mask calculated from min aligned mask and original physical address offset. This affects max mapping size. The mapping size can't achieve the IO_TLB_SEGSIZE * IO_TLB_SIZE when original offset is non-zero. This will cause system boot up failure in Hyper-V Isolation VM where swiotlb force is enabled. Scsi layer use return value of dma_max_mapping_size() to set max segment size and it finally calls swiotlb_max_mapping_size(). Hyper-V storage driver sets min align mask to 4k - 1. Scsi layer may pass 256k length of request buffer with 0~4k offset and Hyper-V storage driver can't get swiotlb bounce buffer via DMA API. Swiotlb_find_slots() can't find 256k length bounce buffer with offset. Make swiotlb_max_mapping _size() take min align mask into account.

[PATCH 5.10] swiotlb: max mapping size takes min align mask into account

by Rishabh Bhatnagar

From: Tianyu Lan <Tianyu.Lan(a)microsoft.com> commit 82806744fd7dde603b64c151eeddaa4ee62193fd upstream. swiotlb_find_slots() skips slots according to io tlb aligned mask calculated from min aligned mask and original physical address offset. This affects max mapping size. The mapping size can't achieve the IO_TLB_SEGSIZE * IO_TLB_SIZE when original offset is non-zero. This will cause system boot up failure in Hyper-V Isolation VM where swiotlb force is enabled. Scsi layer use return value of dma_max_mapping_size() to set max segment size and it finally calls swiotlb_max_mapping_size(). Hyper-V storage driver sets min align mask to 4k - 1. Scsi layer may pass 256k length of request buffer with 0~4k offset and Hyper-V storage driver can't get swiotlb bounce buffer via DMA API. Swiotlb_find_slots() can't find 256k length bounce buffer with offset. Make swiotlb_max_mapping _size() take min align mask into account.

[PATCH v2] x86,acpi: Limit "Dummy wait" workaround to older AMD and Intel processors

by K Prateek Nayak

Processors based on the Zen microarchitecture support IOPORT based deeper C-states. The ACPI idle driver reads the acpi_gbl_FADT.xpm_timer_block.address in the IOPORT based C-state exit path which is claimed to be a "Dummy wait op" and has been around since ACPI's introduction to Linux dating back to Andy Grover's Mar 14, 2002 posting [1]. Old, circa 2002 chipsets have a bug which was elaborated by Andreas Mohr back in 2006 in commit b488f02156d3d ("ACPI: restore comment justifying 'extra' P_LVLx access") where the commit log claims: "this dummy read was about: STPCLK# doesn't get asserted in time on (some) chipsets, which is why we need to have a dummy I/O read to delay further instruction processing until the CPU is fully stopped." This workaround is very painful on modern systems with a large number of cores. The "inl()" can take thousands of cycles. Sampling certain workloads with IBS on AMD Zen3 system shows that a significant amount of time is spent in the dummy op, which incorrectly gets accounted as C-State residency. A large C-State residency value can prime the cpuidle governor to recommend a deeper C-State during the subsequent idle instances, starting a vicious cycle, leading to performance degradation on workloads that rapidly switch between busy and idle phases. (For the extent of the performance degradation refer link [2]) The dummy wait is unnecessary on processors based on the Zen microarchitecture (AMD family 17h+ and HYGON). Skip it to prevent polluting the C-state residency information. Among the pre-family 17h AMD processors, there has been at least one report of an AMD Athlon on a VIA chipset (circa 2006) where this this problem was seen (see [3] for report by Andreas Mohr). Modern Intel processors use MWAIT based C-States in the intel_idle driver and are not impacted by this code path. For older Intel processors that use the acpi_idle driver, a workaround was suggested by Dave Hansen and Rafael J. Wysocki to regard all Intel chipsets using the IOPORT based C-state management as being affected by this problem (see [4] for workaround proposed). For these reasons, mark all the Intel processors and pre-family 17h AMD processors with x86_BUG_STPCLK. In the acpi_idle driver, restrict the dummy wait during IOPORT based C-state transitions to only these processors.

However, it can only do this when the copy_*_user() helpers are, themselves, inline too. Using find_vmap_area() requires taking a spinlock. The check_object_size() helper can call find_vmap_area() when the destination is in vmap memory. If show_regs() is called in interrupt context, it will attempt a call to copy_from_user_nmi(), which may call check_object_size() and then find_vmap_area(). If something in normal context happens to be in the middle of calling find_vmap_area() (with the spinlock held), the interrupt handler will hang forever. The copy_from_user_nmi() call is actually being called with a fixed-size length, so check_object_size() should never have been called in the first place. Given the narrow constraints, just replace the __copy_from_user_inatomic() call with an open-coded version that calls only into the sanitizers and not check_object_size(), followed by a call to raw_copy_from_user().

[merged mm-hotfixes-stable] mm-page_isolation-fix-isolate_single_pageblock-isolation-behavior.patch removed from -mm tree

Its filename was mm-page_isolation-fix-isolate_single_pageblock-isolation-behavior.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Zi Yan <ziy(a)nvidia.com> Subject: mm/page_isolation: fix isolate_single_pageblock() isolation behavior Date: Tue, 13 Sep 2022 22:39:13 -0400 set_migratetype_isolate() does not allow isolating MIGRATE_CMA pageblocks unless it is used for CMA allocation. isolate_single_pageblock() did not have the same behavior when it is used together with set_migratetype_isolate() in start_isolate_page_range(). This allows alloc_contig_range() with migratetype other than MIGRATE_CMA, like MIGRATE_MOVABLE (used by alloc_contig_pages()), to isolate first and last pageblock but fail the rest. The failure leads to changing migratetype of the first and last pageblock to MIGRATE_MOVABLE from MIGRATE_CMA, corrupting the CMA region. This can happen during gigantic page allocations. Like Doug said here: https://lore.kernel.org/linux-mm/a3363a52-883b-dcd1-b77f-f2bb378d6f2d@gmail…, for gigantic page allocations, the user would notice no difference, since the allocation on CMA region will fail as well as it did before. But it might hurt the performance of device drivers that use CMA, since CMA region size decreases. Fix it by passing migratetype into isolate_single_pageblock(), so that set_migratetype_isolate() used by isolate_single_pageblock() will prevent the isolation happening.
