hey, I'm seeing a regression that I bisected down to this change. I installed GNOME on a couple of different server models that have AMI-based BMCs, which provide a web-based graphics display (virtual KVM). When I enter the lock screen on current upstream kernels, the display freezes, and I see the following messages appear in syslog whenever I generate keyboard/mouse events on that display:
Jan 19 20:34:53 starbuck gnome-shell[5002]: Failed to post KMS update: drmModeAtomicCommit: Invalid argument Jan 19 20:34:53 starbuck gnome-shell[5002]: Page flip discarded: drmModeAtomicCommit: Invalid argument Jan 19 20:34:53 starbuck gnome-shell[5002]: Failed to post KMS update: drmModeAtomicCommit: Invalid argument Jan 19 20:34:53 starbuck gnome-shell[5002]: Page flip discarded: drmModeAtomicCommit: Invalid argument Jan 19 20:34:53 starbuck gnome-shell[5002]: Failed to post KMS update: drmModeAtomicCommit: Invalid argument Jan 19 20:34:53 starbuck gnome-shell[5002]: Page flip discarded: drmModeAtomicCommit: Invalid argument Jan 19 20:34:53 starbuck gnome-shell[5002]: Failed to post KMS update: drmModeAtomicCommit: Invalid argument
Thanks for reporting. I'll investigate soon.
Best regards Thomas
If I back out this change w/ the following patch (code has evolved slightly preventing a clean revert), then the lock screen once again behaves normally:
diff --git a/drivers/gpu/drm/ast/ast_mode.c b/drivers/gpu/drm/ast/ast_mode.c index 956c8982192b..336c545c46f5 100644 --- a/drivers/gpu/drm/ast/ast_mode.c +++ b/drivers/gpu/drm/ast/ast_mode.c @@ -1012,9 +1012,6 @@ static int ast_crtc_helper_atomic_check(struct drm_crtc *crtc, const struct drm_format_info *format; bool succ;
- if (!crtc_state->enable)
return 0; /* no mode checks if CRTC is being disabled */- ast_state = to_ast_crtc_state(crtc_state);
format = ast_state->format;
Apologies for noticing so long after the fact. I don't normally run a desktop environment on these servers, I just happened to be debugging something recently that required it.
