Display WA #1178 is meant to fix Aux channel voltage swing too low with some type C dongles. It applies to external ports on combo phy. On Icelake this is port A and B when those are not eDP. v2: follow the spec to the letter: include Aux A and just check if it's not eDP instead of checking only for Aux B.

has_drrs is a flag we can't read out. We set it when seamless DRRS is enabled in pipe_config, so intel_dump_pipe_config() and intel_pipe_config_compare() will continue to do the right thing when has_drrs is set on the real state. This removes one more dereference of crtc->config. While at it, fixup the comment and also read out M2_N2 for CHV, since we program it in the set_m_n function.

Disable master interrupt before reading level indications. This will close a race where we get a level indication between reading and disabling, generating an extra interrupt where we could have avoided one. Further, as the reading acts also as a post, replace the write/post on the irq reset with the helper. On enabling side, posting doesn't serve any purpose so it can also be replaced with helper.

LSPCON chips can generate YCBCR outputs, if asked nicely :). In order to generate YCBCR 4:2:0 outputs, a source must: - send YCBCR 4:4:4 signals to LSPCON - program color space as 4:2:0 in AVI infoframes Whereas for YCBCR 4:4:4 outputs, the source must: - send YCBCR 4:4:4 signals to LSPCON - program color space as 4:4:4 in AVI infoframes So for both 4:2:0 as well as 4:4:4 outputs, we are driving the pipe for YCBCR 4:4:4 output, but AVI infoframe's color space information indicates LSPCON FW to start scaling down from YCBCR 4:4:4 and generate YCBCR 4:2:0 output. As the scaling is done by LSPCON device, we need not to reserve a scaler for 4:2:0 outputs. V2: rebase V3: Addressed review comments from Ville - add enum crtc_output_format instead of bool ycbcr420 - use crtc_output_format=4:4:4 for modeset of LSPCON 4:2:0 output cases in this way we will have YCBCR 4:4:4 framework ready (except the ABI part) V4: Added r-b from Maarten (for v3) Addressed review comments from Ville: - Do not add a non-atomic state variable to determine lspcon output. Instead add bool in CRTC state to indicate lspcon based scaling. V5: Addressed review comments from Ville: - Change the state bool name from external scaling to something more relavent. - Keep the info and adjusted_mode structures const. - use crtc_state instead of pipe_config. - Push all the config change into lspcon_ycbcr420_config function. V6: Rebase, small changes to accommodate changes in patch 2.

In order to pass AVI infoframes to LSPCON devices, a source has to write them in a vendor recommended method and location. This patch series: - adds generic LSPCON infoframe setup functions. - registers these functions into existing AVI infoframe framework. - triggers these functions from modeset sequence. Next patches in the series will add vendor specific code.

Intel LSPCON chip is provided by 2 vendors: - Megachips America (MCA) - Parade technologies (Parade tech) Its important to know the vendor of this chip, as the address to write AVI infoframes is different for those two. This patch reads the vendor OUI signature, and marks into LSPCON encoder structure for future usages.

Currently, we are using a bool in CRTC state (state->ycbcr420), to indicate modeset, that the output format is YCBCR 4:2:0. Now in order to support other YCBCR formats, we will need more such flags. This patch adds a new enum parameter for YCBCR 4:2:0 outputs, in the CRTC output formats and then plugs it during the modeset. V3: Added this patch in the series, to address review comments from second patchset. V4: Added r-b from Maarten (on v3) Addressed review comments from Ville: - Change the enum name to intel_output_format. - Start the enum value (INVALID) from 0 instaed of 1. - Set the crtc's output_format to RGB in encoder's compute_config. V5: Broke previous patch 1 into two parts, - first patch to add CRTC output format in general - second patch (this one) to add YCBCR 4:2:0 output format specifically. - Use ARRAY_SIZE(format_str) for output format validity check (Ville) V6: Added a separate function to calculate crtc_state->output_format, and calling it from various get_config function (Fix CI build warning) V7: Fixed checkpatch warnings for alignment V8: Rebase V9: Rebase V10: Rebase V11: Addressed review comments from Ville: - Change check for CRTC output format from > ARRAY_SIZE to >= ARRAY_SIZE. - Check for values < INTEL_OUTPUT_FORMAT_RGB is unnecessary. - No need to get CRTC YCBCR config, for pre-BDW functions.

We were writing to PLANE_BUF_CFG(pipe, plane_id) twice for every platform, and we were even using different values on the gen10- planar case. The first write is useless since it just gets replaced with the next one, so kill it. There's a lot to improve in the DDB code, but let's start by avoiding the double write. Reviewed-by:

The transition watermarks ask for Selected Result Blocks (the real value), not Result Blocks (the integer value). Given how ceilings are applied in both the non-transition and the transition watermarks calculations, we can get away with assuming that Selected Result Blocks is actually Result Blocks minus 1 without any rounding errors.

Function intel_framebuffer_init() checks for the possibilities during framebuffer creation (addfb ioctl time). It is missing the fact that the indexed format is not supported with Yf tiling. It is worth noticing that skl_plane_format_mod_supported() correctly handles for the C8/Yf combination, but this function runs during modeset time, so we only reject the combination later. Ville recently proposed a new IGT test that only uses addfb to assert supported formats, so that IGT was failing. Add the check so we get green squares right from the start after Ville merges his test. Also drive-by fix the missing /* fall through */ in the chunk we modified by just turning it into a "break;" since IMHO breaks are easier to read than fall-throughs.

For mmap-exhaustion, we deliberately put the system under a large amount of pressure to ensure that we are able to reap mmap-offsets from dead objects. If background activity does that reaping for us, that defeats the purpose of the test and in some cases will fail our sanity checks (because of the fake activity we use to prevent the idle worker).

As mentioned in the previous commit, we currently prevent new modesets on recently-removed MST connectors by returning no encoder from our ->best_encoder() callback once the MST port has disappeared. This is wrong however, because it prevents legacy modesetting users from being able to disable CRTCs on MST connectors after the connector's respective topology has disappeared. So, fix this by instead by just always returning a valid encoder. Changes since v2: - Remove usage of atomic MST helper for now, since that got replaced with a much simpler solution Signed-off-by:
