Attach HDR property for Gen9 devices with MCA LSPCON chips. v2: Cleaned HDR property attachment logic based on capability as per Jani Nikula's suggestion. v3: Fixed the HDR property attachment logic as per the new changes by Kai-Feng to align with lspcon detection failure on some devices. v4: Add HDR proprty in late_register to handle lspcon detection, as suggested by Ville. v5: Init Lspcon only if advertized from BIOS. v6: Added a Todo to plan a cleanup later, added Ville's RB.

Gen9 hardware supports HDMI2.0 through LSPCON chips. Extending HDR support for MCA LSPCON based GEN9 devices. SOC will drive LSPCON as DP and send HDR metadata as standard DP SDP packets. LSPCON will be set to operate in PCON mode, will receive the metadata and create Dynamic Range and Mastering Infoframe (DRM packets) and send it to HDR capable HDMI sink devices. v2: Re-used hsw infoframe write implementation for HDR metadata for LSPCON as per Ville's suggestion. v3: Addressed Jani Nikula's review comments. v4: Addressed Ville's review comments, removed redundant wrapper and checks, passed arguments instead of hardcodings.

LSPCON firmware exposes HDR capability through LPCON_CAPABILITIES DPCD register. LSPCON implementations capable of supporting HDR set HDR_CAPABILITY bit in LSPCON_CAPABILITIES to 1. This patch reads the same, detects the HDR capability and adds this to intel_lspcon struct. v2: Addressed Jani Nikula's review comment and fixed the HDR capability detection logic v3: Deferred HDR detection from lspcon_init (Ville) v4: Addressed Ville's minor review comments, added his RB.

Add the calculations to set plane selective fetch registers depending in the value of the area damaged. It is still using the whole plane area as damaged but that will change in next patches. v2: - fixed new_plane_state->uapi.dst.y2 typo in intel_psr2_sel_fetch_update() - do not shifthing new_plane_state->uapi.dst only src is in 16.16 format BSpec: 55229 Cc: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

We know a problem exists in the ifwi shipped with the early pre-production Tigerlake and DG1 prototypes, later revisions are fine. However, CI still relies on the earlier ifwi and we grow tired of the volume of warnings as we wait for replacements. Since the warning is a bug, we do not want to lose the warning in its entirety, so only suppress the warning for the platforms currently exhibiting the issue. Suggested-by:

Prior to sanitizing the GGTT, the only operations allowed in intel_display_init_nogem() are those to reserve the preallocated (and active) regions in the GGTT leftover from the BIOS. Trying to allocate a GGTT vma (such as intel_pin_and_fence_fb_obj during the initial modeset) may then conflict with other preallocated regions that have not yet been protected. Move the initial modesetting from the end of init_nogem to the beginning of init so that any vma pinning (either framebuffers or DSB, for example), is after the GGTT is ready to handle it. This will prevent the DSB object from being destroyed too early: [ 53.449241] BUG: KASAN: use-after-free in i915_init_ggtt+0x324/0x9e0 [i915] [ 53.449309] Read of size 8 at addr ffff88811b1e8070 by

The current interface of intel_gvt_register_hypervisor() expects a non-const pointer to struct intel_gvt_mpt, even though the mediator never modifies (or should modifiy) the content of this struct. Change the function signature and relevant struct members to const to properly express the API's intent and allow instances of intel_gvt_mpt to be allocated as const. While I was here, I also made KVM's instance of this struct const to reduce the number of writable function pointers in the kernel.

For DG1 we have a little of mix up wrt to DDI/port names and indexes. Bspec refers to the ports as DDIA, DDIB, DDI USBC1 and DDI USBC2 (besides the DDIA, DDIB, DDIC, DDID), but the previous naming is the most unambiguous one. This means that for any register on Display Engine we should use the index of A, B, D and E. However in some places this is not true: - VBT: uses C and D and have to be mapped to D/E - IO/Combo: uses C and D, but we already differentiate those when we created the phy vs port distinction. This additional mapping for VBT and phy are already covered in previous patches, so now we can initialize all the DDIs as A, B, D and E. v2: Squash previous patch enabling just ports A and B since most of the pumbling code is already merged now Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Clinton Taylor <Clinton.A.Taylor@intel.com> Signed-off-by:

After having written the entire OA buffer with reports, the HW will write again at the beginning of the OA buffer. It'll indicate it by setting the WRAP bits in the OASTATUS register. When a wrap happens and that at the end of the read vfunc we write the OASTATUS register back to clear the REPORT_LOST bit, we sometimes see that the OATAILPTR register is reset to a previous position on Gen8/9 (apparently not the case on Gen11+). This leads the next call to the read vfunc to process reports we've already read. Because we've marked those as read by clearing the reason & timestamp dwords, they're discarded and a "Skipping spurious, invalid OA report" message is emitted. The workaround to avoid this OATAILPTR value reset seems to be to set the wrap bits when writing back OASTATUS. This change has no impact on userspace, it only avoids a bunch of DRM_NOTE("Skipping spurious, invalid OA report\n") messages. Signed-off-by:

We can't call drm_plane_state_src() this late for the slave plane since it would consult the wrong uapi state. We've alreayd done the correct uapi->hw copy earlier, so let's just preserve the unclipped src/dst rects using a temp copy across the intel_atomic_plane_check_clipping() call. Signed-off-by:

We need to look at hw.fb for the framebuffer, and add the translation for the slave_plane_state. With these changes we set the correct rectangle on the bigjoiner slave, and don't set incorrect src/dst/visibility on the slave plane. v2: * Manual rebase (Manasi) v3: * hw.rotation instead of uapi.rotation (Ville) Signed-off-by:

When using bigjoiner userspace is only controlling the "master" plane, so use its uapi state for the "slave" plane as well. hw.crtc needs a bit of magic since we don't want to copy that from the uapi state (as it points to the wrong pipe for the "slave " plane). Instead we pass the right crtc in explicitly but only assign it when the uapi state indicates the plane to be logically enabled (ie. uapi.crtc != NULL). Signed-off-by:

Skip iterating over bigjoiner slaves, only the master has the state we care about. Add the width of the bigjoiner slave to the reconstructed fb. Hide the bigjoiner slave to userspace, and double the mode on bigjoiner master. And last, disable bigjoiner slave from primary if reconstruction fails. v3: * Fix the ddi_get_config slave error (Ankit Nautiyal) v2: * Unsupported bigjoiner config for initial fb (Ville) Signed-off-by:

Enabling is done in a special sequence and so should plane updates be. Ideally the end user never notices the second pipe is used. This way ideally everything will be tear free, and updates are really atomic as userspace expects it. This uses generic modeset_enables() calls like trans port sync but still has special handling for disable since for slave we should not disable things like encoder, plls that are not enabled for slave.

When the clock is higher than the dotclock, try with 2 pipes enabled. If we can enable 2, then we will go into big joiner mode, and steal the adjacent crtc. This only links the crtc's in software, no hardware or plane programming is done yet. Blobs are also copied from the master's crtc_state, so it doesn't depend at commit time on the other crtc_state. v6: * Enable dSC for any mode->hdisplay > 5120 v5: * Remove intel_dp_max_dotclock (Manasi) v4: * Fixes in intel_crtc_compute_config (Ville) v3: * Manual Rebase (Manasi) Changes since v1: - Rename pipe timings to transcoder timings, as they are now different. Changes since v2: - Rework bigjoiner checks; always disable slave when recalculating master. No need to have a separate bigjoiner pass any more. - Use pipe_mode instead of transcoder_mode, to clean up the code. Signed-off-by:

When doing the plane state copy from the UV plane to the Y plane let's just copy the hw state directly instead of using the original uapi state. The UV plane has already had its uapi state copied into its hw state, so this extra detour via the uapi state for the Y plane is pointless. Signed-off-by:
