2023-03-21sched/fair: Sanitize vruntime of entity being migratedVincent Guittot
Commit 829c1651e9c4 ("sched/fair: sanitize vruntime of entity being placed") fixes an overflowing bug, but ignore a case that se->exec_start is reset after a migration. For fixing this case, we delay the reset of se->exec_start after placing the entity which se->exec_start to detect long sleeping task. In order to take into account a possible divergence between the clock_task of 2 rqs, we increase the threshold to around 104 days.

2023-03-21entry: Fix noinstr warning in __enter_from_user_mode()Josh Poimboeuf
__enter_from_user_mode() is triggering noinstr warnings with CONFIG_DEBUG_PREEMPT due to its call of preempt_count_add() via ct_state(). The preemption disable isn't needed as interrupts are already disabled. And the context_tracking_enabled() check in ct_state() also isn't needed as that's already being done by the CT_WARN_ON(). Just use __ct_state() instead. Fixes the following warnings: vmlinux.o: warning: objtool: enter_from_user_mode+0xba: call to preempt_count_add() leaves .noinstr.text section vmlinux.o: warning: objtool: syscall_enter_from_user_mode+0xf9: call to preempt_count_add() leaves .noinstr.text section vmlinux.o: warning: objtool: syscall_enter_from_user_mode_prepare+0xc7: call to preempt_count_add() leaves .noinstr.text section vmlinux.o: warning: objtool: irqentry_enter_from_user_mode+0xba: call to preempt_count_add() leaves .noinstr.text section Fixes: 171476775d32 ("context_tracking: Convert state to atomic_t") Signed-off-by: Josh Poimboeuf <jpoimboe@kernel.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lore.kernel.org/r/d8955fa6d68dc955dda19baf13ae014ae27926f5.1677369694.git.jpoimboe@kernel.org
2023-03-21drm: panel-orientation-quirks: Add quirk for Lenovo Yoga Book X90FHans de Goede
Like the Windows Lenovo Yoga Book X91F/L the Android Lenovo Yoga Book X90F/L has a portrait 1200x1920 screen used in landscape mode, add a quirk for this. When the quirk for the X91F/L was initially added it was written to also apply to the X90F/L but this does not work because the Android version of the Yoga Book uses completely different DMI strings. Also adjust the X91F/L quirk to reflect that it only applies to the X91F/L models.

2023-03-21drm/i915/debugfs: add crtc i915_pipe debugfs fileJani Nikula
The pipe may differ from crtc index if pipes are fused off. For testing purposes, IGT needs to know the pipe. There's already a I915_GET_PIPE_FROM_CRTC_ID IOCTL for this. However, the upcoming Xe driver won't have that IOCTL, and going forward, we'll want a unified interface for testing i915 and Xe, as they share the display code. Thus add the debugfs for i915 display. v2: User letters for pipe names (Ville) Cc: Bhanuprakash Modem <bhanuprakash.modem@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Tested-by: Bhanuprakash Modem <bhanuprakash.modem@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230320124429.786985-2-jani.nikula@intel.com

2023-03-21drm/i915/debugfs: Enable upper layer interfaces to act on all gt'sAndi Shyti
The commit 82a149a62b6b ("drm/i915/gt: move remaining debugfs interfaces into gt") moved gt-related debugfs files in the gtX/ directories to operate on individual gt's. However, the original files were only functioning on the root GT (GT 0) and have been left in the same location to maintain compatibility with userspace users. Add multiplexing functionality to the higher directories' files. This enables the operations to be performed on all the GTs with a single write. In the case of reads, the files provide an or'ed value across all the tiles.

When a device has multiple power domains, dev->power_domain is left empty during probe. That didn't cause any issue so far because we are freeloading on smmu driver's vote on cx gdsc. Instead of that, create a device_link between cx genpd device and gmu device to keep a vote from gpu driver.
