An optional follow-on PR for 4.19, on top of previous -fixes PR, which brings in a6xx support. These patches have been on list since earlier in the year (mostly waiting for userspace). They have been in linux-next since earlier in the week, now that we have freedreno userspace working on a6xx[1][2]. So far glmark2, Chromium/ChromiumOS, gnome-shell, glamor, xonotic, etc, are working. And a healthy chuck of deqp works, and I've been busy fixing things. The needed libdrm changes (no new uapi changes needed) are already on master, and the 2nd branch is rebased on that. Signed-off-by:

Since Haswell we have no color range indication either in the pipe or port registers for DP. Instead, there's a separate register for setting the DP Main Stream Attributes (MSA) directly. The MSA register definition makes no references to colorimetry, just a vague reference to the DP spec. The connection to the color range was lost. Apparently we've failed to set the proper MSA bit for limited, or CEA, range ever since the first DDI platforms. We've started setting other MSA parameters since commit dae84799 ("drm/i915: add intel_ddi_set_pipe_settings"). Without the crucial bit of information, the DP sink has no way of knowing the source is actually transmitting limited range RGB, leading to "washed out" colors. With the colorimetry information, compliant sinks should be able to handle the limited range properly. Native (i.e. non-LSPCON) HDMI was not affected because we do pass the color range via AVI infoframes. Though not the root cause, the problem was made worse for DDI platforms with commit 55bc60db ("drm/i915: Add "Automatic" mode for the "Broadcast RGB" property"), which selects limited range RGB automatically based on the mode, as per the DP, HDMI and CEA specs. After all these years, the fix boils down to flipping one bit. [Per testing reports, this fixes DP sinks, but not the LSPCON. My educated guess is that the LSPCON fails to turn the CEA range MSA into AVI infoframes for HDMI.] Reported-by:

On suspend, we cancel the automatic forcewake and clear all other sources of forcewake so the machine can sleep before we do suspend. However, we expose the forcewake to userspace (only via debugfs, but nevertheless we do) and want to restore that upon resume or else our accounting will be off and we may not acquire the forcewake before we use it. So record which domains we cleared on suspend and reacquire them early on resume. v2: Hold the spinlock to appease our sanitychecks v3: s/fw_domains_user/fw_domains_saved/ to convey intent more clearly Reported-by:

An oddity occurs on Sandybridge, Ivybridge and Haswell (and presumably Valleyview) in that for the period following the GPU restart after a reset, there are no GT interrupts received.
