We have the BDB version cached, use it. We're going to have to start doing some of the BDB block parsing later, at which point we may no longer have the VBT around anymore (we free it at the end of intel_bios_init() when it didn't come via OpRegion). Signed-off-by:

When the PHY fails on calibration we were previously skipping the ddi initialization.

If ret isn't zero, it is almost for sure ETIMEDOUT, because we use it in wait_for macro which does continuous retries until timeout is reached. If we still ran out of time and retries, we most likely would be interested in getting status, to understand what was the actual error propagated from PCode, rather than to find out that we had a time out, which is anyway quite obvious, if the function fails. v2: Make it status ? status : ret(thanks Vinod for the hint) Signed-off-by:

Currently skl_pcode_try_request function doesn't properly handle return value it gets from snb_pcode_rw, but treats status != 0 as success, returning true, which basically doesn't allow to use retry/timeout mechanisms if PCode happens to be busy and returns EGAIN or some other status code not equal to 0. We saw this on real hw and also tried simulating this by always returning -EAGAIN from snb_pcode_rw for 6 times, which currently will just result in false success, while it should have tried until timeout is reached: [ 22.357729] i915 0000:00:02.0: [drm:intel_cdclk_dump_config [i915]] Changing CDCLK to 307200 kHz, VCO 614400 kHz, ref 38400 kHz, bypass 19200 kHz, voltage level 0 [ 22.357831] i915 0000:00:02.0: [drm:__snb_pcode_rw [i915]] Returning EAGAIN retry 1 [ 22.357892] i915 0000:00:02.0: [drm:skl_pcode_request [i915]] Success, exiting [ 22.357936] i915 0000:00:02.0: [drm] ERROR Failed to inform PCU about cdclk change (err -11, freq 307200) We see en error because higher level api, still notices that status was wrong, however we still did try only once.

Since gen6 we use FPGA_DBG register to detect unclaimed MMIO registers. This register is in the display engine IP and can only ever detect unclaimed accesses to registers in this area. However sometimes there are reports of this triggering for registers in other areas, which should not be possible. Right now we always warn after the read/write of registers going through unclaimed_reg_debug(). However places using __raw_uncore_* may be triggering the unclaimed access and those being later accounted to a different register. Let's warn both before and after the read/write with a slightly different message, so it's clear if the register reported in the warning is actually the culprit. Commit dda96033 ("drm/i915: Just clear the mmiodebug before a register access") attempted to solve the same issue by removing the warning when if FPGA_DBG flags before the mmio read/write. However, it doesn't solve it completely as FPGA_DBG may remain set when reading registers outside display. So in the end the check after the mmio read/write triggers the warning pointing to the wrong register. Signed-off-by:

Accessing the DDI_BUF_CTL register without the port's DDI clock being enabled (to set/clear the TypeC PHY ownership for the port) can lead to a corrupted value read during any i915 register access right after the DDI clock is enabled. The root cause is the way clock synchronization works for this register, controlled by the CHICKEN_DCPR_1 DDI_CLOCK_REG_ACCESS flag. Correctly this flag should be cleared on ADLP (see the Bspec link below), however after bootup the flag is set. One easily reproducible issue is an unclaimed register access of the PWR_WELL_CTL_DDI2 register, programmed right after DDI clock enabling to enable the port's DDI_IO power well (see the HSDES, VLK links below). With the correct setting above this problem can't be reproduced.

Instead of exit PSR when a frontbuffer invalidation happens, we can enable the PSR2 selective fetch continuous full frame, that will keep the panel updated like PSR was disabled but without keeping PSR active. So as soon as the frontbuffer flush happens we can disable the continuous full frame and start to do selective fetches much quicker than the path that would enable PSR, that will wait a few frames to actually activate PSR. Also this approach has proven to fix some glitches found in Alderlake-P when there are a lot of invalidations happening together with page flips. Some may ask why it is writing to CURSURFLIVE(), it is because that is the way that hardware team provided us to poke display to handle PSR updates, and it is being used since display 9. v2: - handling possible race conditions between frontbuffer rendering and page flips Reviewed-by:

Frontbuffer rendering and page flips can race with each other and this can potentialy cause issues with PSR2 selective fetch. And because pipe/crtc updates are time sentive we can't grab the PSR lock after intel_pipe_update_start() and before intel_pipe_update_end(). So here adding the lock and unlock functions and calls, the proper PSR2 selective fetch handling will come in a separated patch. v2: - fixed new functions documentation Reviewed-by:

The request to aqquire gem resources is failing for DSB in rare scenario where it is busy and the register programming will be done through mmio fallback path. DSB has extra advantage of faster register programming which may go away through mmio path. Adding wait for gem resource also may not be right as anyways losing time.

Our YCbCr output is always supposed to be limited range BT.709. That's what we send with native HDMI. The conn_state->colorspace stuff is entirely independent of that and is not supposed to alter the generated output in any way. If we want a way to do that then we need a new proprty for it. Make it so that the RGB->YCbCr conversion when performed by the DPF will match the BT.709 we would transmit with native HDMI.

Currently we only support "4:2:0 also" modes on native HDMI. Extend that support for DP as well.

Rework the HDMI DFP TMDS clock checks to also check at 8bpc. Previously we only checked the deep color cases. But I suppose a sink could potentially declare "4:2:0 also" modes that only actually fit within its own limits when using 4:2:0.

Merge tag 'perf-tools-for-v5.18-2022-04-02' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux Pull more perf tools updates from Arnaldo Carvalho de Melo: - Avoid SEGV if core.cpus isn't set in 'perf stat'. - Stop depending on .git files for building PERF-VERSION-FILE, used in 'perf --version', fixing some perf tools build scenarios. - Convert tracepoint.py example to python3. - Update UAPI header copies from the kernel sources: socket, mman-common, msr-index, KVM, i915 and cpufeatures. - Update copy of libbpf's hashmap.c. - Directly return instead of using local ret variable in evlist__create_syswide_maps(), found by coccinelle. * tag 'perf-tools-for-v5.18-2022-04-02' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: perf python: Convert tracepoint.py example to python3 perf evlist: Directly return instead of using local ret variable perf cpumap: More cpu map reuse by merge. perf cpumap: Add is_subset function perf evlist: Rename cpus to user_requested_cpus perf tools: Stop depending on .git files for building PERF-VERSION-FILE tools headers cpufeatures: Sync with the kernel sources tools headers UAPI: Sync drm/i915_drm.h with the kernel sources tools headers UAPI: Sync linux/kvm.h with the kernel sources tools kvm headers arm64: Update KVM headers from the kernel sources tools arch x86: Sync the msr-index.h copy with the kernel sources tools headers UAPI: Sync asm-generic/mman-common.h with the kernel perf beauty: Update copy of linux/socket.h with the kernel sources perf tools: Update copy of libbpf's hashmap.c perf stat: Avoid SEGV if core.cpus isn't set
