[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(). That is broken, because patch_text() and patch_text_nosync() takes different parameters (number of instruction vs patched length in bytes).

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.

[PATCH v3 1/3] media: videobuf2: use sgtable-based scatterlist wrappers

by Marek Szyprowski

Use common wrappers operating directly on the struct sg_table objects to fix incorrect use of scatterlists sync calls. dma_sync_sg_for_*() functions have to be called with the number of elements originally passed to dma_map_sg_*() function, not the one returned in sgt->nents.

[PATCH] spi: tegra114: Use value to check for invalid delays

by Aaron Kling via B4 Relay

From: Aaron Kling <webgeek1234(a)gmail.com> A delay unit of 0 is a valid entry, thus it is not valid to check for unused delays. Instead, check the value field; if that is zero, the given delay is unset.

Unplayable framerates in game but specific kernel versions work, maybe amdgpu problem

by machion＠disroot.org

Hello kernel/driver developers, I hope, with my information it's possible to find a bug/problem in the kernel. Otherwise I am sorry, that I disturbed you. I only use LTS kernels, but I can narrow it down to a hand full of them, where it works. The PC: Manjaro Stable/Cinnamon/X11/AMD Ryzen 5 2600/Radeon HD 7790/8GB RAM I already asked the Manjaro community, but with no luck. The game: Hellpoint (GOG Linux latest version, Unity3D-Engine v2021), uses vulkan --- I came a long road of kernels. I had many versions of 5.4, 5.10, 5.15, 6.1 and 6.6 and and the game was always unplayable, because the frames where around 1fps (performance of PC is not the problem). I asked the mesa and cinnamon team for help in the past, but also with no luck. It never worked, till on 2025-03-29 when I installed 6.12.19 for the first time and it worked! But it only worked with 6.12.19, 6.12.20 and 6.12.21 When I updated to 6.12.25, it was back to unplayable. For testing I installed 6.14.4 with the same result. It doesn't work. I also compared file /proc/config.gz of both kernels (6.12.21 <> 6.14.4), but can't seem to see drastic changes to the graphical part. I presume it has something to do with amdgpu. If you need more information, I would be happy to help. Kind regards, Marion

[PATCH] scsi: smartpqi: Fix the race condition between pqi_tmf_worker and pqi_sdev_destroy
