We reference dump buffers both by their handle as well as their object. The problem is now that when anybody iterates over the DRM framebuffers and exports the underlying GEM objects through DMA-buf we run into a circular reference count situation. The result is that the fbdev handling holds the GEM handle preventing the DMA-buf in the GEM object to be released. This DMA-buf in turn holds a reference to the driver module which on unload would release the fbdev. Break that loop by releasing the handle as soon as the DRM framebuffer object is created. The DRM framebuffer and the DRM client buffer structure still hold a reference to the underlying GEM object preventing its destruction. Signed-off-by:

An interrupted dma_fence_wait() becomes an -ERESTARTSYS returned to userspace ioctl(DRM_IOCTL_VIRTGPU_EXECBUFFER) calls, prompting to retry the ioctl(), but the passed exbuf->fence_fd has been reset to -1, making the retry attempt fail at sync_file_get_fence(). The uapi for DRM_IOCTL_VIRTGPU_EXECBUFFER is changed to retain the passed value for exbuf->fence_fd when returning anything besides a successful result from the ioctl.

The unprepare sequence has started to fail after moving to panel bridge code in the msm drm driver (commit 007ac026 ("drm/msm/dsi: switch to DRM_PANEL_BRIDGE")). You'll see messages like this in the kernel logs: panel-boe-tv101wum-nl6 ae94000.dsi.0: failed to set panel off: -22 This is because boe_panel_enter_sleep_mode() needs an operating DSI link to set the panel into sleep mode. Performing those writes in the unprepare phase of bridge ops is too late, because the link has already been torn down by the DSI controller in post_disable, i.e. the PHY has been disabled, etc. See dsi_mgr_bridge_post_disable() for more details on the DSI . Split the unprepare function into a disable part and an unprepare part. For now, just the DSI writes to enter sleep mode are put in the disable function. This fixes the panel off routine and keeps the panel happy. My Wormdingler has an integrated touchscreen that stops responding to touch if the panel is only half disabled too. This patch fixes it. And finally, this saves power when the screen is off because without this fix the regulators for the panel are left enabled when nothing is being displayed on the screen.

Starting from Turing, the driver is no longer responsible for initiating DEVINIT when required as the GPU started loading a FW image from ROM and executing DEVINIT itself after power-on. However - we apparently still need to wait for it to complete. This should correct some issues with runpm on some systems, where we get control of the HW before it's been fully reinitialised after resume from suspend. Signed-off-by:

Commit 622113b9 ("drm/ssd130x: Replace simple display helpers with the atomic helpers") changed the driver to just use the atomic helpers instead of the simple KMS abstraction layer. But the commit also made a subtle change on the display power sequence and initialization order, by moving the ssd130x_power_on() call to the encoder .atomic_enable handler and the ssd130x_init() call to CRTC .reset handler. Before this change, both ssd130x_power_on() and ssd130x_init() were called in the simple display pipeline .enable handler, so the display was already initialized by the time the SSD130X_DISPLAY_ON command was sent. For some reasons, it only made the ssd130x SPI driver to fail but the I2C was still working. That is the reason why the bug was not noticed before. To revert to the old driver behavior, move the ssd130x_init() call to the encoder .atomic_enable as well. Besides fixing the panel not being turned on when using SPI, it also gets rid of the custom CRTC .reset callback.

The DRM fbdev emulation layer sets the struct fb_info .fbdefio field to a struct fb_deferred_io pointer, that is shared across all drivers that use the generic drm_fbdev_generic_setup() helper function. It is a problem because the fbdev core deferred I/O logic assumes that the struct fb_deferred_io data is not shared between devices, and it's stored there state such as the list of pages touched and a mutex that is use to synchronize between the fb_deferred_io_track_page() function that track the dirty pages and fb_deferred_io_work() workqueue handler doing the actual deferred I/O. The latter can lead to the following error, since it may happen that two drivers are probed and then one is removed, which causes the mutex bo be destroyed and not existing anymore by the time the other driver tries to grab it for the fbdev deferred I/O logic: [ 369.756553] ------------[ cut here ]------------ [ 369.756604] DEBUG_LOCKS_WARN_ON(lock->magic != lock) [ 369.756631] WARNING: CPU: 2 PID: 1023 at kernel/locking/mutex.c:582 __mutex_lock+0x348/0x424 [ 369.756744] Modules linked in: nf_conntrack_netbios_ns nf_conntrack_broadcast nft_fib_inet nft_fib_ipv4 nft_fib_ipv6 nft_fib nft_reject_inet nf_reject_ipv4 nf_reject_ipv6 nft_reject nft_ct nft_chain_nat nf_nat nf_conntrack nf_defrag_ip v6 nf_defrag_ipv4 ip_set nf_tables nfnetlink qrtr btsdio bluetooth sunrpc brcmfmac snd_soc_hdmi_codec cpufreq_dt cfg80211 vfat fat vc4 rfkill brcmutil raspberrypi_cpufreq i2c_bcm2835 iproc_rng200 bcm2711_thermal snd_soc_core snd_pcm_dmaen gine leds_gpio nvmem_rmem joydev hid_cherry uas usb_storage gpio_raspberrypi_exp v3d snd_pcm raspberrypi_hwmon gpu_sched bcm2835_wdt broadcom bcm_phy_lib snd_timer genet snd mdio_bcm_unimac clk_bcm2711_dvp soundcore drm_display_helper pci e_brcmstb cec ip6_tables ip_tables fuse [ 369.757400] CPU: 2 PID: 1023 Comm: fbtest Not tainted 5.19.0-rc6+ #94 [ 369.757455] Hardware name: raspberrypi,4-model-b Raspberry Pi 4 Model B Rev 1.4/Raspberry Pi 4 Model B Rev 1.4, BIOS 2022.10 10/01/2022 [ 369.757538] pstate: 00400005 (nzcv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 369.757596] pc : __mutex_lock+0x348/0x424 [ 369.757635] lr : __mutex_lock+0x348/0x424 [ 369.757672] sp : ffff80000953bb00 [ 369.757703] x29: ffff80000953bb00 x28: ffff17fdc087c000 x27: 0000000000000002 [ 369.757771] x26: ffff17fdc349f9b0 x25: fffffc5ff72e0100 x24: 0000000000000000 [ 369.757838] x23: 0000000000000000 x22: 0000000000000002 x21: ffffa618df636f10 [ 369.757903] x20: ffff80000953bb68 x19: ffffa618e0f18138 x18: 0000000000000001 [ 369.757968] x17: 0000000020000000 x16: 0000000000000002 x15: 0000000000000000 [ 369.758032] x14: 0000000000000000 x13: 284e4f5f4e524157 x12: 5f534b434f4c5f47 [ 369.758097] x11: 00000000ffffdfff x10: ffffa618e0c79f88 x9 : ffffa618de472484 [ 369.758162] x8 : 000000000002ffe8 x7 : c0000000ffffdfff x6 : 00000000000affa8 [ 369.758227] x5 : 0000000000001fff x4 : 0000000000000000 x3 : 0000000000000027 [ 369.758292] x2 : 0000000000000001 x1 : ffff17fdc087c000 x0 : 0000000000000028 [ 369.758357] Call trace: [ 369.758383] __mutex_lock+0x348/0x424 [ 369.758420] mutex_lock_nested+0x4c/0x5c [ 369.758459] fb_deferred_io_mkwrite+0x78/0x1d8 [ 369.758507] do_page_mkwrite+0x5c/0x19c [ 369.758550] wp_page_shared+0x70/0x1a0 [ 369.758590] do_wp_page+0x3d0/0x510 [ 369.758628] handle_pte_fault+0x1c0/0x1e0 [ 369.758670] __handle_mm_fault+0x250/0x380 [ 369.758712] handle_mm_fault+0x17c/0x3a4 [ 369.758753] do_page_fault+0x158/0x530 [ 369.758792] do_mem_abort+0x50/0xa0 [ 369.758831] el0_da+0x78/0x19c [ 369.758864] el0t_64_sync_handler+0xbc/0x150 [ 369.758904] el0t_64_sync+0x190/0x194 [ 369.758942] irq event stamp: 11395 [ 369.758973] hardirqs last enabled at (11395): [<ffffa618de472554>] __up_console_sem+0x74/0x80 [ 369.759042] hardirqs last disabled at (11394): [<ffffa618de47254c>] __up_console_sem+0x6c/0x80 [ 369.760554] softirqs last enabled at (11392): [<ffffa618de330a74>] __do_softirq+0x4c4/0x6b8 [ 369.762060] softirqs last disabled at (11383): [<ffffa618de3c9124>] __irq_exit_rcu+0x104/0x214 [ 369.763564] ---[ end trace 0000000000000000 ]--- Fixes: d536540f ("drm/fb-helper: Add generic fbdev emulation .fb_probe function") Signed-off-by:

drm_vma_node_allow() and drm_vma_node_revoke() should be called in balanced pairs. We call drm_vma_node_allow() once per-file everytime a user calls mmap_offset, but only call drm_vma_node_revoke once per-file on each mmap_offset. As the mmap_offset is reused by the client, the per-file vm_count may remain non-zero and the rbtree leaked. Call drm_vma_node_allow_once() instead to prevent that memory leak.

Currently there is no easy way for a drm driver to safely check and allow drm_vma_offset_node for a drm file just once. Allow drm drivers to call non-refcounted version of drm_vma_node_allow() so that a driver doesn't need to keep track of each drm_vma_node_allow() to call subsequent drm_vma_node_revoke() to prevent memory leak.

Commit 374146ca ("drm/vc4: Switch to drmm_mutex_init") converted, among other functions, vc4_create_object() to use drmm_mutex_init(). However, that function is used to allocate a BO, and therefore the mutex needs to be freed much sooner than when the DRM device is removed from the system. For each buffer allocation we thus end up allocating a small structure as part of the DRM-managed mechanism that is never freed, eventually leading us to no longer having any free memory anymore. Let's switch back to mutex_init/mutex_destroy to deal with it properly. Fixes: 374146ca ("drm/vc4: Switch to drmm_mutex_init") Reviewed-by:

The drm_sched_entity_kill() is invoked twice by drm_sched_entity_destroy() while userspace process is exiting or being killed. First time it's invoked when sched entity is flushed and second time when entity is released. This causes a lockup within wait_for_completion(entity_idle) due to how completion API works. Calling wait_for_completion() more times than complete() was invoked is a error condition that causes lockup because completion internally uses counter for complete/wait calls. The complete_all() must be used instead in such cases. This patch fixes lockup of Panfrost driver that is reproducible by killing any application in a middle of 3d drawing operation.

ipu_src_rect_width() was introduced to support odd screen resolutions such as 1366x768 by internally rounding up primary plane width to a multiple of 8 and compensating with reduced horizontal blanking. This also caused overlay plane width to be rounded up, which was not intended. Fix overlay plane width by limiting the rounding up to the primary plane. drm_rect_width(&new_state->src) >> 16 is the same value as drm_rect_width(dst) because there is no plane scaling support.

The drm_sched_entity_kill() is invoked twice by drm_sched_entity_destroy() while userspace process is exiting or being killed. First time it's invoked when sched entity is flushed and second time when entity is released. This causes a lockup within wait_for_completion(entity_idle) due to how completion API works. Calling wait_for_completion() more times than complete() was invoked is a error condition that causes lockup because completion internally uses counter for complete/wait calls. The complete_all() must be used instead in such cases. This patch fixes lockup of Panfrost driver that is reproducible by killing any application in a middle of 3d drawing operation.

The virtio_gpu_object_shmem_init() will alloc memory and save it in @ents, so when virtio_gpu_array_alloc() fails, this memory should be freed, this patch fixes it. Fixes: e7fef092 ("drm/virtio: Simplify error handling of virtio_gpu_object_create()") Signed-off-by:

Having a bigger number of FIFO lines held after vsync is only useful to SoCs using AFBC to give time to the AFBC decoder to be reset, configured and enabled again. For SoCs not using AFBC this, on the contrary, is causing on some displays issues and a few pixels vertical offset in the displayed image. Conditionally increase the number of lines held after vsync only for SoCs using AFBC, leaving the default value for all the others. Fixes: 24e0d405 ("drm/meson: hold 32 lines after vsync to give time for AFBC start") Signed-off-by:
