Enable runtime pm by default so GPU suspend when idle for 200ms. This value can be changed by autosuspend_delay_ms in device's power sysfs dir. On Allwinner H3 lima_device_resume takes ~40us and lima_device_suspend takes ~20us. Tested-by:

This reverts commit 6bb0942e. Unfortunately it would appear that the rumors we've heard of sideband message interleaving not being very well supported are true. On the Lenovo ThinkPad Thunderbolt 3 dock that I have, interleaved messages appear to just get dropped: [drm:drm_dp_mst_wait_tx_reply [drm_kms_helper]] timedout msg send 00000000571ddfd0 2 1 [dp_mst] txmsg cur_offset=2 cur_len=2 seqno=1 state=SENT path_msg=1 dst=00 [dp_mst] type=ENUM_PATH_RESOURCES contents: [dp_mst] port=2 DP descriptor for this hub: OUI 90-cc-24 dev-ID SYNA3 HW-rev 1.0 SW-rev 3.12 quirks 0x0008 It would seem like as well that this is a somewhat well known issue in the field. From section 5.4.2 of the DisplayPort 2.0 specification: There are MST Sink/Branch devices in the field that do not handle interleaved message transactions. To facilitate message transaction handling by downstream devices, an MST Source device shall generate message transactions in an atomic manner (i.e., the MST Source device shall not concurrently interleave multiple message transactions). Therefore, an MST Source device shall clear the Message_Sequence_No value in the Sideband_MSG_Header to 0. MST Source devices that support field policy updates by way of software should update the policy to forego the generation of interleaved message transactions. This is a bit disappointing, as features like HDCP require that we send a sideband request every ~2 seconds for each active stream. However, there isn't really anything in the specification that allows us to accurately probe for interleaved messages. If it ends up being that we -really- need this in the future, we might be able to whitelist hubs where interleaving is known to work-or maybe try some sort of heuristics. But for now, let's just play it safe and not use it. Signed-off-by:

The ast driver inherits from DRM's CRTC state, but still uses the atomic helper for struct drm_crtc_funcs.reset, drm_atomic_helper_crtc_reset(). The helper only allocates enough memory for the core CRTC state. That results in an out-ouf-bounds access when duplicating the initial CRTC state. Simplified backtrace shown below: [ 21.469321] ================================================================== [ 21.469434] BUG: KASAN: slab-out-of-bounds in ast_crtc_atomic_duplicate_state+0x84/0x100 [ast] [ 21.469445] Read of size 8 at addr ffff888036c1c5f8 by task systemd-udevd/382 [ 21.469451] [ 21.469464] CPU: 2 PID: 382 Comm: systemd-udevd Tainted: G E 5.5.0-rc6-1-default+ #214 [ 21.469473] Hardware name: Sun Microsystems SUN FIRE X2270 M2/SUN FIRE X2270 M2, BIOS 2.05 07/01/2010 [ 21.469480] Call Trace: [ 21.469501] dump_stack+0xb8/0x110 [ 21.469528] print_address_description.constprop.0+0x1b/0x1e0 [ 21.469557] ? ast_crtc_atomic_duplicate_state+0x84/0x100 [ast] [ 21.469581] ? ast_crtc_atomic_duplicate_state+0x84/0x100 [ast] [ 21.469597] __kasan_report.cold+0x1a/0x35 [ 21.469640] ? ast_crtc_atomic_duplicate_state+0x84/0x100 [ast] [ 21.469665] kasan_report+0xe/0x20 [ 21.469693] ast_crtc_atomic_duplicate_state+0x84/0x100 [ast] [ 21.469733] drm_atomic_get_crtc_state+0xbf/0x1c0 [ 21.469768] __drm_atomic_helper_set_config+0x81/0x5a0 [ 21.469803] ? drm_atomic_plane_check+0x690/0x690 [ 21.469843] ? drm_client_rotation+0xae/0x240 [ 21.469876] drm_client_modeset_commit_atomic+0x230/0x390 [ 21.469888] ? __mutex_lock+0x8f0/0xbe0 [ 21.469929] ? drm_client_firmware_config.isra.0+0xa60/0xa60 [ 21.469948] ? drm_client_modeset_commit_force+0x28/0x230 [ 21.470031] ? memset+0x20/0x40 [ 21.470078] drm_client_modeset_commit_force+0x90/0x230 [ 21.470110] drm_fb_helper_restore_fbdev_mode_unlocked+0x5f/0xc0 [ 21.470132] drm_fb_helper_set_par+0x59/0x70 [ 21.470155] fbcon_init+0x61d/0xad0 [ 21.470185] ? drm_fb_helper_restore_fbdev_mode_unlocked+0xc0/0xc0 [ 21.470232] visual_init+0x187/0x240 [ 21.470266] do_bind_con_driver+0x2e3/0x460 [ 21.470321] do_take_over_console+0x20a/0x290 [ 21.470371] do_fbcon_takeover+0x85/0x100 [ 21.470402] register_framebuffer+0x2fd/0x490 [ 21.470425] ? kzalloc.constprop.0+0x10/0x10 [ 21.470503] __drm_fb_helper_initial_config_and_unlock+0xf2/0x140 [ 21.470533] drm_fbdev_client_hotplug+0x162/0x250 [ 21.470563] drm_fbdev_generic_setup+0xd2/0x155 [ 21.470602] ast_driver_load+0x688/0x850 [ast] <...> [ 21.472625] ================================================================== Allocating enough memory for struct ast_crtc_state in a custom ast CRTC reset handler fixes the problem. v2: * implement according to drm_atomic_helper_crtc_reset() * update state with __drm_atomic_helper_crtc_reset() Signed-off-by:

The driver forgets to free the I/O region in remove and probe failure. Add the missed calls to fix it. Since the success of request_region() is optional, add the "region" field in vesafb_par to represent whether request_region() succeeds. Then only call release_region() when "region" is not null.

The fbdev framework doesn't care to call the .set_power callback only on changes. So the driver has to care for itself that the regulator doesn't get disabled more often than enabled. This fixes the regulator warning unbalanced disables for lcd supply which can be triggered by doing echo 4 > /sys/class/lcd/imxfb-lcd/lcd_power twice. Signed-off-by:
