[PATCH v6.1] md: move initialization and destruction of 'io_acct_set' to md.c

by Yu Kuai

From: Yu Kuai <yukuai3(a)huawei.com> commit c567c86b90d4715081adfe5eb812141a5b6b4883 upstream. 'io_acct_set' is only used for raid0 and raid456, prepare to use it for raid1 and raid10, so that io accounting from different levels can be consistent. By the way, follow up patches will also use this io clone mechanism to make sure 'active_io' represents in flight io, not io that is dispatching, so that mddev_suspend will wait for io to be done as designed.

That meant that, when a buffer containing vertex data was written to, it was necessary to issue a PIPE_CONTROL::VF Cache Invalidate to invalidate any VF L2 cachelines associated with that buffer, so the new value would be properly read from memory. Since Tigerlake and later, VERTEX_BUFFER_STATE and 3DSTATE_INDEX_BUFFER have included an "L3 Bypass Enable" bit which userspace drivers can set to request that the vertex fetcher unit snoop L3. However, unlike most true L3 clients, the "VF Cache Invalidate" bit continues to only invalidate the VF L2 cache - and not any associated L3 lines. To handle that, PIPE_CONTROL has a new "L3 Read Only Cache Invalidation Bit", which according to the docs, "controls the invalidation of the Geometry streams cached in L3 cache at the top of the pipe." In other words, the vertex and index buffer data that gets cached in L3 when "L3 Bypass Disable" is set. Mesa always sets L3 Bypass Disable so that the VF unit snoops L3, and whenever it issues a VF Cache Invalidate, it also issues a L3 Read Only Cache Invalidate so that both L2 and L3 vertex data is invalidated. xe is issuing VF cache invalidates too (which handles cases like CPU writes to a buffer between GPU batches). Because userspace may enable L3 snooping, it needs to issue an L3 Read Only Cache Invalidate as well. Fixes significant flickering in Firefox on Meteorlake, which was writing to vertex buffers via the CPU between batches; the missing L3 Read Only invalidates were causing the vertex fetcher to read stale data from L3.

[PATCH 6.6 0/2] PCI: imx6: Fix i.MX7D controller_id backport regression

by Ryan Matthews

Hello, This fixes an i.Mx 7D SoC PCIe regression caused by a backport mistake. The regression is broken PCIe initialization and for me a boot hang. I don't know how to organize this. I think a revert and redo best captures what's happening. To complicate things, it looks like the redo patch could also be applied to 5.4, 5.10, 5.15, and 6.1. But those versions don't have the original backport commit. Version 6.12 matches master and needs no change. One conflict resolution is needed to apply the redo patch back to versions 6.1 -> 5.15 -> 5.10. One more resolution to apply back to -> 5.4. Patches against those other versions aren't included here. -- Ryan Richard Zhu (1): PCI: imx6: Skip controller_id generation logic for i.MX7D Ryan Matthews (1): Revert "PCI: imx6: Skip controller_id generation logic for i.MX7D" drivers/pci/controller/dwc/pci-imx6.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) base-commit: 814637ca257f4faf57a73fd4e38888cce88b5911 -- 2.47.2

[PATCH stable v6.6] riscv: Pass patch_text() the length in bytes

by Nam Cao

From: Samuel Holland <samuel.holland(a)sifive.com> [ Upstream commit 51781ce8f4486c3738a6c85175b599ad1be71f89 ] patch_text_nosync() already handles an arbitrary length of code, so this removes a superfluous loop and reduces the number of icache flushes. Reviewed-by: Björn Töpel <bjorn(a)rivosinc.com> Signed-off-by: Samuel Holland <samuel.holland(a)sifive.com> Reviewed-by: Conor Dooley <conor.dooley(a)microchip.com> Link: https://lore.kernel.org/r/20240327160520.791322-6-samuel.holland@sifive.com Signed-off-by: Palmer Dabbelt <palmer(a)rivosinc.com> [apply to v6.6] Signed-off-by: Nam Cao <namcao(a)linutronix.de> --- this patch fixes a bug introduced by commit b1756750a397 ("riscv: kprobes: Use patch_text_nosync() for insn slots"), which replaced patch_text() with patch_text_nosync().

Carlos reports an earlier patch, c0cd6f557b90 ("mm: page_alloc: fix freelist movement during block conversion"), as the root cause for a regression in worst-case zone->lock+irqoff hold times. Both of these patches modify the page allocator's fallback path to be less greedy in an effort to stave off fragmentation. The flip side of this is that fallbacks are also less productive each time around, which means the fallback search can run much more frequently. Carlos' traces point to rmqueue_bulk() specifically, which tries to refill the percpu cache by allocating a large batch of pages in a loop. It highlights how once the native freelists are exhausted, the fallback code first scans orders top-down for whole blocks to claim, then falls back to a bottom-up search for the smallest buddy to steal. For the next batch page, it goes through the same thing again. This can be made more efficient. Since rmqueue_bulk() holds the zone->lock over the entire batch, the freelists are not subject to outside changes; when the search for a block to claim has already failed, there is no point in trying again for the next page. Modify __rmqueue() to remember the last successful fallback mode, and restart directly from there on the next rmqueue_bulk() iteration. Oliver confirms that this improves beyond the regression that the test robot reported against c2f6ea38fc1b: commit: f3b92176f4 ("tools/selftests: add guard region test for /proc/$pid/pagemap") c2f6ea38fc ("mm: page_alloc: don't steal single pages from biggest buddy") acc4d5ff0b ("Merge tag 'net-6.15-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net") 2c847f27c3 ("mm: page_alloc: speed up fallbacks in rmqueue_bulk()") <--- your patch f3b92176f4f7100f c2f6ea38fc1b640aa7a2e155cc1 acc4d5ff0b61eb1715c498b6536 2c847f27c37da65a93d23c237c5 ---------------- --------------------------- --------------------------- --------------------------- %stddev %change %stddev %change %stddev %change %stddev \ | \ | \ | \ 25525364 ± 3% -56.4% 11135467 -57.8% 10779336 +31.6% 33581409 vm-scalability.throughput Carlos confirms that worst-case times are almost fully recovered compared to before the earlier culprit patch: 2dd482ba627d (before freelist hygiene): 1ms c0cd6f557b90 (after freelist hygiene): 90ms next-20250319 (steal smallest buddy): 280ms this patch : 8ms [jackmanb(a)google.com: comment updates] Link: https://lkml.kernel.org/r/D92AC0P9594X.3BML64MUKTF8Z@google.com [hannes(a)cmpxchg.org: reset rmqueue_mode in rmqueue_buddy() error loop, per Yunsheng Lin] Link: https://lkml.kernel.org/r/20250409140023.GA2313@cmpxchg.org Link: https://lkml.kernel.org/r/20250407180154.63348-1-hannes@cmpxchg.org Fixes: c0cd6f557b90 ("mm: page_alloc: fix freelist movement during block conversion") Fixes: c2f6ea38fc1b ("mm: page_alloc: don't steal single pages from biggest buddy") Signed-off-by: Johannes Weiner <hannes(a)cmpxchg.org> Signed-off-by: Brendan Jackman <jackmanb(a)google.com> Reported-by: kernel test robot <oliver.sang(a)intel.com> Reported-by: Carlos Song <carlos.song(a)nxp.com> Tested-by: Carlos Song <carlos.song(a)nxp.com> Tested-by: kernel test robot <oliver.sang(a)intel.com> Closes: https://lore.kernel.org/oe-lkp/202503271547.fc08b188-lkp@intel.com Reviewed-by: Brendan Jackman <jackmanb(a)google.com> Tested-by: Shivank Garg <shivankg(a)amd.com> Acked-by: Zi Yan <ziy(a)nvidia.com> Reviewed-by: Vlastimil Babka <vbabka(a)suse.cz> Cc: <stable(a)vger.kernel.org> [6.10+] Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> diff --git a/mm/page_alloc.c b/mm/page_alloc.c index 9a219fe8e130..1715e34b91af 100644 --- a/mm/page_alloc.c +++ b/mm/page_alloc.c @@ -2183,23 +2183,15 @@ try_to_claim_block(struct zone *zone, struct page *page, } /* - * Try finding a free buddy page on the fallback list. - * - * This will attempt to claim a whole pageblock for the requested type - * to ensure grouping of such requests in the future. - * - * If a whole block cannot be claimed, steal an individual page, regressing to - * __rmqueue_smallest() logic to at least break up as little contiguity as - * possible. + * Try to allocate from some fallback migratetype by claiming the entire block, + * i.e. converting it to the allocation's start migratetype. * * The use of signed ints for order and current_order is a deliberate * deviation from the rest of this file, to make the for loop * condition simpler. - * - * Return the stolen page, or NULL if none can be found. */ static __always_inline struct page * -__rmqueue_fallback(struct zone *zone, int order, int start_migratetype, +__rmqueue_claim(struct zone *zone, int order, int start_migratetype, unsigned int alloc_flags) { struct free_area *area; @@ -2237,14 +2229,29 @@ __rmqueue_fallback(struct zone *zone, int order, int start_migratetype, page = try_to_claim_block(zone, page, current_order, order, start_migratetype, fallback_mt, alloc_flags); - if (page) - goto got_one; + if (page) { + trace_mm_page_alloc_extfrag(page, order, current_order, + start_migratetype, fallback_mt); + return page; + } } - if (alloc_flags & ALLOC_NOFRAGMENT) - return NULL; + return NULL; +} + +/* + * Try to steal a single page from some fallback migratetype.
