When an MST connector stays enabled during a commit the connector's MST state needs to be added to the atomic state, but the corresponding MST payload allocation shouldn't be set for deletion; fix such modesets by ensuring the above even if the connector was already enabled before the modeset.

On BDW+ M/N are double buffered and so we can easily reprogram them during a fastset. So for eDP panels that support seamless DRRS we can just change these without a full modeset. For earlier platforms we'd need to play tricks with M1/N1 vs. M2/N2 during the fastset to make sure we do the switch atomically. Not sure the added complexity is worth the hassle, so leave it alone for now. The slight downside is that we have to keep the link running at a link rate capable of supporting the highest refresh rate we want to use. For the moment we just pick the highest mode the panel reports and calculate the link based on that. This might need further refinement (eg. if we run into bandwidth restrictions)... v2: Only use the high link rate if the platform really supports the seamless M/N change uring fastset (ie. bdw+) v3: Rebase due to HAS_DOUBLE_BUFFERED_M_N() Reviewed-by:Mika Kahola <mika.kahola@intel.com> Signed-off-by:

Add a function to get the fixed_mode with the highest clock. The plan is to use this for the link bw calculation on seamless DRRS panels so that we alwasy end up with the same link params regardless of the requested refresh rate.

Now that we no longer do the fuzzy clock and M/N checks we can get rid of the fastset state copy hacks. Reviewed-by:

Ville Syrjälä authored
To make the fastboot checks at least somewhat sensible let's mark the expected DPLL as the active one right after we finished the state computation. Otherwise intel_pipe_config_compare() will always be comparing things against NULL/0. TODO: This is still not really right. If the previous commit had to fall back to the other PLL then the comparisong will now fail. I guess intel_pipe_config_compare() should rather be comparing port_dplls[] instead. But to do that we really should just unify every platform to use the port_dplls[] approach whether they have any need for PLL fallbacks or not. Acked-by:

Now that we no longer fuzz M/N during fastset these should match exctly. In order to get a match with what the BIOS does we need to round M/N down.

Only reassign the pipe's DPLL if it's going through a full .compute_config() cycle. If OTOH it's just getting modeset eg. in order to change cdclk there doesn't seem much point in picking a new DPLL for it. This should also prevent .get_dplls() from seeing a funky port_clock for DP even in cases where the readout produces a non-standard clock and we (for some reason) have decided to not fully recompute the state to remedy the situation. Reviewed-by:
-
Ville Syrjälä authored
Currently we calculate a lot of things (pixel rate, watermarks, cdclk) trusting that the DPLL can generate the exact frequency we ask it. In practice that is not true and there can be certain amount of rounding involved. To allow us to eventually get accurate numbers for all our DPLL clock derived state we need to move the DPLL calculation to hapen much earlier. To that end we hoist it up to the just after the fastset checks. For now we just do the easy code motion, and the actual back feeding of the final DPLL clock into the state will come later. A slight change here is that now .crtc_compute_clock() can get called while the shared_dpll is still assigned. But since .crtc_compute_clock() no longer assignes new shared_dplls this is perfectly fine. TODO: I'd actually like to do this before the fastset check so that if the DPLL state should change we actually do the modeset. Which I think is what the video aficionados want, but it might not be what the fans of fastboot want. Not yet sure how to reconcile those conflicting requirements... v2: s/return/goto/ in error handling Reviewed-by:

Javier Martinez Canillas authored
The simple display pipeline is a set of helpers that can be used by DRM drivers to avoid dealing with all the needed components and just define a few functions to operate a simple display device with one full-screen scanout buffer feeding a single output. But it is arguable that this provides the correct level of abstraction for simple drivers, and recently some have been ported from using these simple display helpers to use the regular atomic helpers instead. The rationale for this is that the simple display pipeline helpers don't hide that much of the DRM complexity, while adding an indirection layer that conflates the concepts of CRTCs and planes. This makes the helpers less flexible and harder to be reused among different graphics drivers. Also, for simple drivers, using the full atomic helpers doesn't require a lot of additional code. So adding a simple display pipeline layer may not be worth it. For these reasons, let's follow that trend and make ssd130x a plain DRM driver that creates its own primary plane, CRTC, enconder and connector. Suggested-by:

Ring push/pop actions for release_ring can be performed normally. But call qxl_ring_init_hdr(qdev->release_ring) will eventually set notify_on_prod to number of QXL_RELEASE_RING_SIZE, affect the value of notify in qxl_push_free_res() function always be false, QEMU will no longer send events of QXL_INTERRUPT_DISPLAY to the guest qxl driver，so qxl_ring_pop() will never been called anymore， and can't do dma_fence_signal(),result to ttm_bo_wait_ctx(bo, ctx) always return EBUSY,fail to call qxl_bo_create(). Test scenario: 1) start virtual machine with qemu command "-device qxl-vga" 2) click suspend botton to enter suspend mode 3) resume and observe the error message in kernel logs,screen will be black Let's fix this by reset io and remove the qxl_ring_init_hdr calling.

VGA_IS1_RC is the color mode register (VGA_IS1_RM the one for monochrome mode, note C vs. M at the end). So when using VGA_IS1_RC make sure the vga device is actually in color mode and set the corresponding bit in the misc register. Reproducible when booting VMs in UEFI mode with some edk2 versions (edk2 fix is on the way too). Doesn't happen in BIOS mode because in that case the vgabios already flips the bit.
