Bos can be put with multiple unrelated dma-resv locks held. But imported bos attempt to grab the bo dma-resv during dma-buf detach that typically happens during cleanup. That leads to lockde splats similar to the below and a potential ABBA deadlock. Fix this by always taking the delayed workqueue cleanup path for imported bos. Requesting stable fixes from when the Xe driver was introduced, since its usage of drm_exec and wide vm dma_resvs appear to be the first reliable trigger of this.

Starting with kernel 6.7, the framebuffer text console is not working anymore with the virtio-gpu device on s390x hosts. Such big endian fb devices are usinga different pixel ordering than little endian devices, e.g. DRM_FORMAT_BGRX8888 instead of DRM_FORMAT_XRGB8888. This used to work fine as long as drm_client_buffer_addfb() was still calling drm_mode_addfb() which called drm_driver_legacy_fb_format() internally to get the right format. But drm_client_buffer_addfb() has recently been reworked to call drm_mode_addfb2() instead with the format value that has been passed to it as a parameter (see commit 6ae2ff23 ("drm/client: Convert drm_client_buffer_addfb() to drm_mode_addfb2()"). That format parameter is determined in drm_fbdev_generic_helper_fb_probe() via the drm_mode_legacy_fb_format() function - which only generates formats suitable for little endian devices. So to fix this issue switch to drm_driver_legacy_fb_format() here instead to take the device endianness into consideration.

Retrieving the system framebuffer's parent device in sysfb_init() increments the parent device's reference count. Hence release the reference before leaving the init function. Adding the sysfb platform device acquires and additional reference for the parent. This keeps the parent device around while the system framebuffer is in use. Signed-off-by:

Since the debugfs functions have no-op stubs for CONFIG_DEBUG_FS=n, the compiler will optimize the rest away since they are no longer referenced. The benefit of removing the conditional compilation is that the build is actually tested for both CONFIG_DEBUG_FS configuration values. Assuming most developers have it enabled, CONFIG_DEBUG_FS=n is not tested much and may fail the build due to the conditional compilation. Reported-by:

Based on grepping through the source code this driver appears to be missing a call to drm_atomic_helper_shutdown() at system shutdown time. Among other things, this means that if a panel is in use that it won't be cleanly powered off at system shutdown time. The fact that we should call drm_atomic_helper_shutdown() in the case of OS shutdown/restart comes straight out of the kernel doc "driver instance overview" in drm_drv.c. This driver users the component model and shutdown happens in the base driver. The "drvdata" for this driver will always be valid if shutdown() is called and as of commit 2a073968 ("drm/atomic-helper: drm_atomic_helper_shutdown(NULL) should be a noop") we don't need to confirm that "drm" is non-NULL.

Based on grepping through the source code, this driver appears to be missing a call to drm_atomic_helper_shutdown() at system shutdown time. This is important because drm_atomic_helper_shutdown() will cause panels to get disabled cleanly which may be important for their power sequencing. Future changes will remove any custom powering off in individual panel drivers so the DRM drivers need to start getting this right.

This happens when the amdgpu_bo_release_notify running before amdgpu_ttm_set_buffer_funcs_status set the buffer funcs to enabled. check the buffer funcs enablement before calling the fill buffer memory. v2:(Christian) - Apply it only for GEM buffers and since GEM buffers are only allocated/freed while the driver is loaded we never run into the issue to clear with buffer funcs disabled. v3:(Mario) - drop the stable tag as this will presumably go into a -fixes PR for 6.10 Log snip: *ERROR* Trying to clear memory with ring turned off.

Device managed panel bridge wrappers are created by calling to drm_panel_bridge_add_typed() and registering a release handler for clean-up when the device gets unbound. Since the memory for this bridge is also managed and linked to the panel device, the release function should not try to free that memory. Moreover, the call to devm_kfree() inside drm_panel_bridge_remove() will fail in this case and emit a warning because the panel bridge resource is no longer on the device resources list (it has been removed from there before the call to release handlers).

When reading EDID fails and driver reports no modes available, the DRM core adds an artificial 1024x786 mode to the connector. Unfortunately some variants of the Exynos HDMI (like the one in Exynos4 SoCs) are not able to drive such mode, so report a safe 640x480 mode instead of nothing in case of the EDID reading failure. This fixes the following issue observed on Trats2 board since commit 13d5b040 ("drm/exynos: do not return negative values from .get_modes()"): [drm] Exynos DRM: using 11c00000.fimd device for DMA mapping operations exynos-drm exynos-drm: bound 11c00000.fimd (ops fimd_component_ops) exynos-drm exynos-drm: bound 12c10000.mixer (ops mixer_component_ops) exynos-dsi 11c80000.dsi: [drm:samsung_dsim_host_attach] Attached s6e8aa0 device (lanes:4 bpp:24 mode-flags:0x10b) exynos-drm exynos-drm: bound 11c80000.dsi (ops exynos_dsi_component_ops) exynos-drm exynos-drm: bound 12d00000.hdmi (ops hdmi_component_ops) [drm] Initialized exynos 1.1.0 20180330 for exynos-drm on minor 1 exynos-hdmi 12d00000.hdmi: [drm:hdmiphy_enable.part.0] *ERROR* PLL could not reach steady state panel-samsung-s6e8aa0 11c80000.dsi.0: ID: 0xa2, 0x20, 0x8c exynos-mixer 12c10000.mixer: timeout waiting for VSYNC ------------[ cut here ]------------ WARNING: CPU: 1 PID: 11 at drivers/gpu/drm/drm_atomic_helper.c:1682 drm_atomic_helper_wait_for_vblanks.part.0+0x2b0/0x2b8 [CRTC:70:crtc-1] vblank wait timed out Modules linked in: CPU: 1 PID: 11 Comm: kworker/u16:0 Not tainted 6.9.0-rc5-next-20240424 #14913 Hardware name: Samsung Exynos (Flattened Device Tree) Workqueue: events_unbound deferred_probe_work_func Call trace: unwind_backtrace from show_stack+0x10/0x14 show_stack from dump_stack_lvl+0x68/0x88 dump_stack_lvl from __warn+0x7c/0x1c4 __warn from warn_slowpath_fmt+0x11c/0x1a8 warn_slowpath_fmt from drm_atomic_helper_wait_for_vblanks.part.0+0x2b0/0x2b8 drm_atomic_helper_wait_for_vblanks.part.0 from drm_atomic_helper_commit_tail_rpm+0x7c/0x8c drm_atomic_helper_commit_tail_rpm from commit_tail+0x9c/0x184 commit_tail from drm_atomic_helper_commit+0x168/0x190 drm_atomic_helper_commit from drm_atomic_commit+0xb4/0xe0 drm_atomic_commit from drm_client_modeset_commit_atomic+0x23c/0x27c drm_client_modeset_commit_atomic from drm_client_modeset_commit_locked+0x60/0x1cc drm_client_modeset_commit_locked from drm_client_modeset_commit+0x24/0x40 drm_client_modeset_commit from __drm_fb_helper_restore_fbdev_mode_unlocked+0x9c/0xc4 __drm_fb_helper_restore_fbdev_mode_unlocked from drm_fb_helper_set_par+0x2c/0x3c drm_fb_helper_set_par from fbcon_init+0x3d8/0x550 fbcon_init from visual_init+0xc0/0x108 visual_init from do_bind_con_driver+0x1b8/0x3a4 do_bind_con_driver from do_take_over_console+0x140/0x1ec do_take_over_console from do_fbcon_takeover+0x70/0xd0 do_fbcon_takeover from fbcon_fb_registered+0x19c/0x1ac fbcon_fb_registered from register_framebuffer+0x190/0x21c register_framebuffer from __drm_fb_helper_initial_config_and_unlock+0x350/0x574 __drm_fb_helper_initial_config_and_unlock from exynos_drm_fbdev_client_hotplug+0x6c/0xb0 exynos_drm_fbdev_client_hotplug from drm_client_register+0x58/0x94 drm_client_register from exynos_drm_bind+0x160/0x190 exynos_drm_bind from try_to_bring_up_aggregate_device+0x200/0x2d8 try_to_bring_up_aggregate_device from __component_add+0xb0/0x170 __component_add from mixer_probe+0x74/0xcc mixer_probe from platform_probe+0x5c/0xb8 platform_probe from really_probe+0xe0/0x3d8 really_probe from __driver_probe_device+0x9c/0x1e4 __driver_probe_device from driver_probe_device+0x30/0xc0 driver_probe_device from __device_attach_driver+0xa8/0x120 __device_attach_driver from bus_for_each_drv+0x80/0xcc bus_for_each_drv from __device_attach+0xac/0x1fc __device_attach from bus_probe_device+0x8c/0x90 bus_probe_device from deferred_probe_work_func+0x98/0xe0 deferred_probe_work_func from process_one_work+0x240/0x6d0 process_one_work from worker_thread+0x1a0/0x3f4 worker_thread from kthread+0x104/0x138 kthread from ret_from_fork+0x14/0x28 Exception stack(0xf0895fb0 to 0xf0895ff8) ... irq event stamp: 82357 hardirqs last enabled at (82363): [<c01a96e8>] vprintk_emit+0x308/0x33c hardirqs last disabled at (82368): [<c01a969c>] vprintk_emit+0x2bc/0x33c softirqs last enabled at (81614): [<c0101644>] __do_softirq+0x320/0x500 softirqs last disabled at (81609): [<c012dfe0>] __irq_exit_rcu+0x130/0x184 ---[ end trace 0000000000000000 ]--- exynos-drm exynos-drm: [drm] *ERROR* flip_done timed out exynos-drm exynos-drm: [drm] *ERROR* [CRTC:70:crtc-1] commit wait timed out exynos-drm exynos-drm: [drm] *ERROR* flip_done timed out exynos-drm exynos-drm: [drm] *ERROR* [CONNECTOR:74:HDMI-A-1] commit wait timed out exynos-drm exynos-drm: [drm] *ERROR* flip_done timed out exynos-drm exynos-drm: [drm] *ERROR* [PLANE:56:plane-5] commit wait timed out exynos-mixer 12c10000.mixer: timeout waiting for VSYNC Cc: stable@vger.kernel.org Fixes: 13d5b040 ("drm/exynos: do not return negative values from .get_modes()") Signed-off-by:

Pull clk fix from Stephen Boyd: "One fix for the SiFive PRCI clocks so that the device boots again. This driver was registering clkdev lookups that were always going to be useless. This wasn't a problem until clkdev started returning an error in these cases, causing this driver to fail probe, and thus boot to fail because clks are essential for most drivers. The fix is simple, don't use clkdev because this is a DT based system where clkdev isn't used" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: clk: sifive: Do not register clkdevs for PRCI clocks
