2024-03-11drm/qxl: Provide qxl_bo_{pin,unpin}_locked()Thomas Zimmermann
Rename __qxl_bo_pin() to qxl_bo_pin_locked() and update all callers. The function will be helpful for implementing the GEM pin callback with correct semantics. Same for __qxl_bo_unpin().

2024-03-11drm/panfrost: Replace fdinfo's profiling debugfs knob with sysfsAdrián Larumbe
Debugfs isn't always available in production builds that try to squeeze every single byte out of the kernel image, but we still need a way to toggle the timestamp and cycle counter registers so that jobs can be profiled for fdinfo's drm engine and cycle calculations. Drop the debugfs knob and replace it with a sysfs file that accomplishes the same functionality, and document its ABI in a separate file.

2024-03-11ynl: samples: fix recycling rate calculationJakub Kicinski
Running the page-pool sample on production machines under moderate networking load shows recycling rate higher than 100%: $ page-pool eth0[2] page pools: 14 (zombies: 0) refs: 89088 bytes: 364904448 (refs: 0 bytes: 0) recycling: 100.3% (alloc: 1392:2290247724 recycle: 469289484:1828235386) Note that outstanding refs (89088) == slow alloc * cache size (1392 * 64) which means this machine is recycling page pool pages perfectly, not a single page has been released. The extra 0.3% is because sample ignores allocations from the ptr_ring. Treat those the same as alloc_fast, the ring vs cache alloc is already captured accurately enough by recycling stats. With the fix: $ page-pool eth0[2] page pools: 14 (zombies: 0) refs: 89088 bytes: 364904448 (refs: 0 bytes: 0) recycling: 100.0% (alloc: 1392:2331141604 recycle: 473625579:1857460661) Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2024-03-11drm/panthor: Fix undefined panthor_device_suspend/resume symbol issueBoris Brezillon
panthor_device_resume/suspend() are only compiled when CONFIG_PM is enabled but panthro_drv.c doesn't use the pm_ptr() macro to conditionally discard resume/suspend assignments, which causes undefined symbol errors at link time when !PM. We could fix that by using pm_ptr(), but supporting the !PM case makes little sense (the whole point of these embedded GPUs is to be low power, so proper PM is a basic requirement in that case). So let's just enforce the presence of CONFIG_PM with a Kconfig dependency instead. If someone needs to relax this dependency, it can be done in a follow-up.

Herve Codina says: ==================== Add support for QMC HDLC This series introduces the QMC HDLC support. Patches were previously sent as part of a full feature series and were previously reviewed in that context: "Add support for QMC HDLC, framer infrastructure and PEF2256 framer" [1] In order to ease the merge, the full feature series has been split and needed parts were merged in v6.8-rc1: - "Prepare the PowerQUICC QMC and TSA for the HDLC QMC driver" [2] - "Add support for framer infrastructure and PEF2256 framer" [3] This series contains patches related to the QMC HDLC part (QMC HDLC driver): - Introduce the QMC HDLC driver (patches 1 and 2) - Add timeslots change support in QMC HDLC (patch 3) - Add framer support as a framer consumer in QMC HDLC (patch 4) Compare to the original full feature series, a modification was done on patch 3 in order to use a coherent prefix in the commit title. I kept the patches unsquashed as they were previously sent and reviewed. Of course, I can squash them if needed. Compared to the previous iteration: https://lore.kernel.org/linux-kernel/20240306080726.167338-1-herve.codina@bootlin.com/ this v7 series mainly: - Rename a variable. - Fix reverse xmas tree declarations. - Add 'Acked-by' tag. ==================== Signed-off-by: David S.

2024-03-11kbuild: remove GCC's default -Wpacked-bitfield-compat flagMasahiro Yamada
Commit 4a5838ad9d2d ("kbuild: Add extra gcc checks") added the -Wpacked-bitfield-compat flag, but there is no need to add it explicitly. GCC manual says: "This warning is enabled by default. Use -Wno-packed-bitfield-compat to disable this warning." The test code in the manual: struct foo { char a:4; char b:8; } __attribute__ ((packed)); ... emits "note: offset of packed bit-field ‘b’ has changed in GCC 4.4" without W=3. Let's remove it, as it is a default with GCC. Clang does not support this flag, so its removal will not affect Clang builds.
