The builtin size check isn't really the right thing for AMD modifiers due to a couple of reasons: 1) In the format structs we don't do set any of the tilesize / blocks etc. to avoid having format arrays per modifier/GPU 2) The pitch on the main plane is pixel_pitch * bytes_per_pixel even for tiled ... 3) The pitch for the DCC planes is really the pixel pitch of the main surface that would be covered by it ... Note that we only handle GFX9+ case but we do this after converting the implicit modifier to an explicit modifier, so on GFX9+ all framebuffers should be checked here. There is a TODO about DCC alignment, but it isn't worse than before and I'd need to dig a bunch into the specifics. Getting this out in a reasonable timeframe to make sure it gets the appropriate testing seemed more important. Finally as I've found that debugging addfb2 failures is a pita I was generous adding explicit error messages to every failure case.

drm_modeset_lock_all() is not needed here, so it is replaced with drm_modeset_lock(). The crtc list around which we are looping never changes, therefore the only lock we need is to protect access to crtc->state. Suggested-by:

Add emit mem sync callback for sdma_v5_0 In amdgpu sync object test, three threads created jobs to send GFX IB and SDMA IB in sequence. After the first GFX thread joined, sometimes the third thread will reuse the same physical page to store the SDMA IB. There will be a risk that SDMA will read GFX IB in the previous physical page. So it's better to flush the cache before commit sdma IB. Acked-by:

[WHY] To process AUX transactions with DMUB using inbox1 and outbox1 mail boxes. [How] 1) Added inbox1 command DMUB_CMD__DP_AUX_ACCESS to issue AUX commands to DMUB in dc_process_dmub_aux_transfer_async(). DMUB processes AUX cmd with DCN and sends reply back in an outbox1 message triggering an outbox1 interrupt to driver. 2) In existing driver implementation, AUX commands are processed synchronously by configuring DCN reg. But in DMUB AUX, driver sends an inbox1 message and waits for a conditional variable (CV) which will be signaled by outbox1 ISR. 3) DM will retrieve Outbox1 message and send back reply to upper layer and complete the AUX command Signed-off-by:
