* devcoredump : Serialize devcd_del workMukesh Ojha2022-09-241-2/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In following scenario(diagram), when one thread X running dev_coredumpm() adds devcd device to the framework which sends uevent notification to userspace and another thread Y reads this uevent and call to devcd_data_write() which eventually try to delete the queued timer that is not initialized/queued yet. So, debug object reports some warning and in the meantime, timer is initialized and queued from X path. and from Y path, it gets reinitialized again and timer->entry.pprev=NULL and try_to_grab_pending() stucks. To fix this, introduce mutex and a boolean flag to serialize the behaviour. cpu0(X) cpu1(Y) dev_coredump() uevent sent to user space device_add() ======================> user space process Y reads the uevents writes to devcd fd which results into writes to devcd_data_write() mod_delayed_work() try_to_grab_pending() del_timer() debug_assert_init() INIT_DELAYED_WORK() schedule_delayed_work() debug_object_fixup() timer_fixup_assert_init() timer_setup() do_init_timer() /* Above call reinitializes the timer to timer->entry.pprev=NULL and this will be checked later in timer_pending() call. */ timer_pending() !hlist_unhashed_lockless(&timer->entry) !h->pprev /* del_timer() checks h->pprev and finds it to be NULL due to which try_to_grab_pending() stucks. */ Link: https://lore.kernel.org/lkml/2e1f81e2-428c-f11f-ce92-eb11048cb271@quicinc.com/ Signed-off-by: Mukesh Ojha <quic_mojha@quicinc.com> Link: https://lore.kernel.org/r/1663073424-13663-1-git-send-email-quic_mojha@quicinc.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The first is a revert of the "fw_devlink.strict=1" default option that we keep trying to enable, but we keep finding platforms that this just breaks everything on. So again, we need it reverted and hopefully it can be worked on in future releases. The second is a sysfs file-size bugfix that resolves an issue that many people are starting to hit as the fix it is fixing also was backported to stable kernels. The util-linux developers are starting to get bugreports about sysfs files that contain no data because of this problem, and this fix which has been in linux-next in the bitfield tree for a long time, resolves it. I'm submitting it here as it needs to be merged for 6.0-final, not for 6.1-rc1. Both of these have been in linux-next with no reported issues, only reports were that these fixed problems" * tag 'driver-core-6.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: drivers/base: Fix unsigned comparison to -1 in CPUMAP_FILE_MAX_BYTES Revert "driver core: Set fw_devlink.strict=1 by default"

This patch reads the DWC_USB3_AWIDTH bits of GHWPARAMS0 which used for the DMA address width, and only configure 64-bit DMA mask if the DWC_USB3_AWIDTH is 64.

A setting of 24 is the correct color depth, but G200ER doesn't seem to be able to use the respective RGB888 color format. Using 24-bit color with forced 32 bpp works around the problem.

That's because that function calls drm_crtc_wait_one_vblank(), which requires the vblank irq to be enabled. Previously mtk_dsi_stop(), being in mtk_dsi_poweroff() and guarded by a refcount, would only be called at the end of mtk_drm_crtc_atomic_disable(), through the call to mtk_crtc_ddp_hw_fini(). Commit cde7e2e35c28 ("drm/mediatek: Separate poweron/poweroff from enable/disable and define new funcs") moved the mtk_dsi_stop() call to mtk_output_dsi_disable(), causing it to be called before mtk_drm_crtc_atomic_disable(), and consequently generating vblank timeout warnings during suspend. Move the mtk_dsi_stop() call back to mtk_dsi_poweroff() so that we have a working vblank irq during mtk_drm_crtc_atomic_disable() and stop getting vblank timeout warnings.

However, some compositors will not attach zpos information to each DRM plane. Consequently, in amdgpu, we default layer_index to 0 and do not update it. This causes said DC logic to enable HW cursor on all planes of the same layer_index, which manifests as a double cursor issue if one of the planes is scaled (and hence scaling the cursor as well). [How] Use DRM core helpers to calculate a normalized_zpos value for each drm_plane_state under each crtc, within the atomic state. This helper will first consider existing zpos values, and if identical/unset, fallback to plane ID ordering. The normalized_zpos is then passed to dc_plane_info during atomic check for later use by the cursor logic.

However, there is a risk of triggering kernel warning on contexts list not empty at driver release time if we deleagate that task to a worker for i915_gem_context_release_work(), unless that work is flushed first. Unfortunately, it is not flushed on driver release. Fix it. Instead of additionally calling flush_workqueue(), either directly or via a new dedicated wrapper around it, replace last call to i915_gem_drain_freed_objects() with existing i915_gem_drain_workqueue() that performs both tasks.
