[PATCH v3 1/3] mm/huge_memory: don't ignore queried cachemode in vmf_insert_pfn_pud()

by David Hildenbrand

We setup the cache mode but ... don't forward the updated pgprot to insert_pfn_pud(). Only a problem on x86-64 PAT when mapping PFNs using PUDs that require a special cachemode. Fix it by using the proper pgprot where the cachemode was setup. It is unclear in which configurations we would get the cachemode wrong: through vfio seems possible. Getting cachemodes wrong is usually ... bad. As the fix is easy, let's backport it to stable. Identified by code inspection.

[PATCH v3] ata: ahci: Disallow LPM for ASUSPRO-D840SA motherboard

by Niklas Cassel

A user has bisected a regression which causes graphical corruptions on his screen to commit 7627a0edef54 ("ata: ahci: Drop low power policy board type"). Simply reverting commit 7627a0edef54 ("ata: ahci: Drop low power policy board type") makes the graphical corruptions on his screen to go away. (Note: there are no visible messages in dmesg that indicates a problem with AHCI.) The user also reports that the problem occurs regardless if there is an HDD or an SSD connected via AHCI, so the problem is not device related. The devices also work fine on other motherboards, so it seems specific to the ASUSPRO-D840SA motherboard. While enabling low power modes for AHCI is not supposed to affect completely unrelated hardware, like a graphics card, it does however allow the system to enter deeper PC-states, which could expose ACPI issues that were previously not visible (because the system never entered these lower power states before). There are previous examples where enabling LPM exposed serious BIOS/ACPI bugs, see e.g. commit 240630e61870 ("ahci: Disable LPM on Lenovo 50 series laptops with a too old BIOS"). Since there hasn't been any BIOS update in years for the ASUSPRO-D840SA motherboard, disable LPM for this board, in order to avoid entering lower PC-states, which triggers graphical corruptions.

[PATCH] drm/i915/snps_hdmi_pll: Fix 64-bit divisor truncation by using div64_u64

by Ankit Nautiyal

DIV_ROUND_CLOSEST_ULL uses do_div(), which expects a 32-bit divisor. When passing a 64-bit constant like CURVE2_MULTIPLIER, the value is silently truncated to u32, potentially leading to incorrect results on large divisors. Replace DIV_ROUND_CLOSEST_ULL with div64_u64(), which correctly handles full 64-bit division. Since the result is clamped between 1 and 127, rounding is unnecessary and truncating division is sufficient.

[PATCH v2 0/6] media: ti, cdns: Multiple pixel support and misc fixes

by Jai Luthra

Hi, The first four patches in this series are miscellaneous fixes and improvements in the Cadence and TI CSI-RX drivers around probing, fwnode and link creation. The last two patches add support for transmitting multiple pixels per clock on the internal bus between Cadence CSI-RX bridge and TI CSI-RX wrapper. As this internal bus is 32-bit wide, the maximum number of pixels that can be transmitted per cycle depend upon the format's bit width. Secondly, the downstream element must support unpacking of multiple pixels. Thus we export a module function that can be used by the downstream driver to negotiate the pixels per cycle on the output pixel stream of the Cadence bridge.

[PATCH v2 0/5] drm/xe: enable driver usage on non-4KiB kernels

by Mingcong Bai via B4 Relay

This patch series attempts to enable the use of xe DRM driver on non-4KiB kernel page platforms. This involves fixing the ttm/bo interface, as well as parts of the userspace API to make use of kernel `PAGE_SIZE' for alignment instead of the assumed `SZ_4K', it also fixes incorrect usage of `PAGE_SIZE' in the GuC and ring buffer interface code to make sure all instructions/commands were aligned to 4KiB barriers (per the Programmer's Manual for the GPUs covered by this DRM driver). This issue was first discovered and reported by members of the LoongArch user communities, whose hardware commonly ran on 16KiB-page kernels. The patch series began on an unassuming branch of a downstream kernel tree maintained by Shang Yatsen.[^1] It worked well but remained sparsely documented, a lot of the work done here relied on Shang Yatsen's original patch. AOSC OS then picked it up[^2] to provide Intel Xe/Arc support for users of its LoongArch port, for which I worked extensively on. After months of positive user feedback and from encouragement from Kexy Biscuit, my colleague at the community, I decided to examine its potential for upstreaming, cross-reference kernel and Intel documentation to better document and revise this patch. Now that this series has been tested good (for boot up, OpenGL, and playback of a standardised set of video samples[^3] on the following platforms (motherboard + GPU model): - x86-64, 4KiB kernel page: - MS-7D42 + Intel Arc A580 - COLORFIRE B760M-MEOW WIFI D5 + Intel Arc B580 - LoongArch, 16KiB kernel page: - XA61200 + GUNNIR DG1 Blue Halberd (Intel DG1) - XA61200 + GUNNIR Iris Xe Index 4 (Intel DG1) - XA61200 + GUNNIR Intel Iris Xe Max Index V2 (Intel DG1) - XA61200 + GUNNIR Intel Arc A380 Index 6G (Intel Arc A380) - XA61200 + ASRock Arc A380 Challenger ITX OC (Intel Arc A380) - XA61200 + Intel Arc A580 - XA61200 + GUNNIR Intel Arc A750 Photon 8G OC (Intel Arc A750) - XA61200 + Intel Arc B580 - XB612B0 + GUNNIR Intel Iris Xe Max Index V2 (Intel DG1) - XB612B0 + GUNNIR Intel Arc A380 Index 6G (Intel Arc A380) - ASUS XC-LS3A6M + GUNNIR Intel Arc B580 INDEX 12G (Intel Arc B580) On these platforms, basic functionalities tested good but the driver was unstable with occasional resets (I do suspect however, that this platform suffers from PCIe coherence issues, as instability only occurs under heavy VRAM I/O load): - AArch64, 4KiB/64KiB kernel pages: - ERUN-FD3000 (Phytium D3000) + GUNNIR Intel Iris Xe Max Index V2 (Intel DG1) - ERUN-FD3000 (Phytium D3000) + GUNNIR Intel Arc A380 Index 6G (Intel Arc A380) - ERUN-FD3000 (Phytium D3000) + GUNNIR Intel Arc A750 Photon 8G OC (Intel Arc A750) I think that this patch series is now ready for your comment and review. Please forgive me if I made any simple mistake or used wrong terminologies, but I have never worked on a patch for the DRM subsystem and my experience is still quite thin. But anyway, just letting you all know that Intel Xe/Arc works on non-4KiB kernel page platforms (and honestly, it's great to use, especially for games and media playback)! [^1]: https://github.com/FanFansfan/loongson-linux/tree/loongarch-xe [^2]: We maintained Shang Yatsen's patch until our v6.13.3 tree, until we decided to test and send this series upstream, https://github.com/AOSC-Tracking/linux/tree/aosc/v6.13.3 [^3]: Delicious hot pot! https://repo.aosc.io/ahvl/sample-videos-20250223.tar.zst --- Matthew(s), Lucas, and Francois: Thanks again for your patience and review. I recently had a job change and it put me off this series for months, but I'm back (and should be a lot more responsive now) - sorry! Let's get this ball rolling again. I was unfortunately unable to revise 1/5 from v1 as you requested, neither of your suggestions to allow allocation of VRAM smaller than page size worked... So I kept that part as is. As for the your comment in 5/5, I'm not sure about what the right approach to implement a SZ_64K >= PAGE_SIZE assert was, as there are many other instances of similar ternary conditional operators in the xe code. Correct me if I'm wrong but I felt that it might be better handled in a separate patch series? --- Changes in v2: - Define `GUC_ALIGN' and use them in GuC code to improve clarity. - Update documentation on `DRM_XE_QUERY_CONFIG_MIN_ALIGNMENT'. - Rebase, and other minor changes. - Link to v1: https://lore.kernel.org/all/20250226-xe-non-4k-fix-v1-0-80f23b5ee40e@aosc.i… To: Lucas De Marchi <lucas.demarchi(a)intel.com> To: Thomas Hellström <thomas.hellstrom(a)linux.intel.com> To: Rodrigo Vivi <rodrigo.vivi(a)intel.com> To: Maarten Lankhorst <maarten.lankhorst(a)linux.intel.com> To: Maxime Ripard <mripard(a)kernel.org> To: Thomas Zimmermann <tzimmermann(a)suse.de> To: David Airlie <airlied(a)gmail.com> To: Simona Vetter <simona(a)ffwll.ch> To: José Roberto de Souza <jose.souza(a)intel.com> To: Francois Dugast <francois.dugast(a)intel.com> To: Matthew Brost <matthew.brost(a)intel.com> To: Alan Previn <alan.previn.teres.alexis(a)intel.com> To: Zhanjun Dong <zhanjun.dong(a)intel.com> To: Matt Roper <matthew.d.roper(a)intel.com> To: Mateusz Naklicki <mateusz.naklicki(a)intel.com> Cc: Mauro Carvalho Chehab <mauro.chehab(a)linux.intel.com> Cc: Zbigniew Kempczyński <zbigniew.kempczynski(a)intel.com> Cc: intel-xe(a)lists.freedesktop.org Cc: dri-devel(a)lists.freedesktop.org Cc: linux-kernel(a)vger.kernel.org Suggested-by: Kexy Biscuit <kexybiscuit(a)aosc.io> Co-developed-by: Shang Yatsen <429839446(a)qq.com> Signed-off-by: Shang Yatsen <429839446(a)qq.com> Signed-off-by: Mingcong Bai <jeffbai(a)aosc.io> --- Mingcong Bai (5): drm/xe/bo: fix alignment with non-4KiB kernel page sizes drm/xe/guc: use GUC_SIZE (SZ_4K) for alignment drm/xe/regs: fix RING_CTL_SIZE(size) calculation drm/xe: use 4KiB alignment for cursor jumps drm/xe/query: use PAGE_SIZE as the minimum page alignment drivers/gpu/drm/xe/regs/xe_engine_regs.h | 2 +- drivers/gpu/drm/xe/xe_bo.c | 8 ++++---- drivers/gpu/drm/xe/xe_guc.c | 4 ++-- drivers/gpu/drm/xe/xe_guc.h | 3 +++ drivers/gpu/drm/xe/xe_guc_ads.c | 32 ++++++++++++++++---------------- drivers/gpu/drm/xe/xe_guc_capture.c | 8 ++++---- drivers/gpu/drm/xe/xe_guc_ct.c | 2 +- drivers/gpu/drm/xe/xe_guc_log.c | 5 +++-- drivers/gpu/drm/xe/xe_guc_pc.c | 4 ++-- drivers/gpu/drm/xe/xe_migrate.c | 4 ++-- drivers/gpu/drm/xe/xe_query.c | 2 +- include/uapi/drm/xe_drm.h | 7 +++++-- 12 files changed, 44 insertions(+), 37 deletions(-) --- base-commit: 546b1c9e93c2bb8cf5ed24e0be1c86bb089b3253 change-id: 20250603-upstream-xe-non-4k-v2-4acf253c9bfd Best regards, -- Mingcong Bai <jeffbai(a)aosc.io>
