In the future we may have more than one FBC instance on some platforms. So let's just allocate it dynamically. This also lets us fully hide the implementation from prying eyes. Signed-off-by:

In order to better encapsulate the FBC implementation introduce a small helper to do the plane<->FBC instance association. We'll also try to structure the plane init code such that introducing multiple FBC instances will be easier down the line. Signed-off-by:

In order to encapsulate FBC harder let's just move the debugfs stuff into intel_fbc.c. Signed-off-by:

The underrun code doesn't need to know any details about FBC, so just pass in the whole device rather than a specific FBC instance. We could make this a bit more fine grained by also passing in the pipe to intel_fbc_handle_fifo_underrun_irq() and letting the FBC code figure which FBC instance (if any) is active on said pipe. But that seems a bit overkill for this so don't bother. Signed-off-by:

Ville Syrjälä authored
In the future we may have multiple planes on the same pipe capable of using FBC. Prepare for that by tracking FBC usage per-plane rather than per-crtc. v2: s/intel_get_crtc_for_pipe/intel_crtc_for_pipe/ Signed-off-by:
-
Ville Syrjälä authored
Pass the FBC instance instead of the crtc to a bunch of places. We also adjust intel_fbc_post_update() to do the intel_fbc_get_reg_params() things instead of doing it from the lower level function (which also gets called for front buffer tracking). Nothing in there will change during front buffer updates. Signed-off-by:

The FBC state cache and params are now nearly identical. Just use the same structure for both. Signed-off-by:
-
Ville Syrjälä authored
There isn't a good reason why we'd have to cache all this plane state stuff in the FBC state. Instead we can just pre-calculate what FBC will really need. Signed-off-by:

Move intel_fbc_override_cfb_stride() next to its cousins. Helps with later patches. Signed-off-by:
-
Ville Syrjälä authored
There's no need to store all this stuff in intel_fbc_state_cache. Just check it all against the plane/crtc states and store only what we need. Probably more should get nuked still, but this is a start. So what we'll do is: - each plane will check its own state and update its local no_fbc_reason - the per-plane no_fbc_reason (if any) then gets propagated to the cache->no_fbc_reason while doing the actual update - fbc->no_fbc_reason gets updated in the end with either the value from the cache or directly from frontbuffer tracking It's still a bit messy, but should hopefuly get cleaned up more in the future. At least now we can observe each plane's reasons for rejecting FBC now more consistently, and we don't have so mcuh redundant state store all over the place. v2: store no_fbc_reason per-plane instead of per-pipe Signed-off-by:
-
Ville Syrjälä authored
No reason to burden the caller with the details on how the minimum compression limit is calculated, so just pass in the whole plane state instead of just the cpp value. Signed-off-by:
-
Ville Syrjälä authored
The ilk fbc watermark computation uses intel_fbc_is_active() which is racy since we don't know whether FBC will be enabled or not at some point. So let's just assume it will be if both HAS_FBC() and the modparam agree. Signed-off-by:

Ville Syrjälä authored
Let's just stick to 32bit mmio accesses so we can get rid of the bare "uncore" reg access in display code. The register are defined as 32bit in the spec anyway. We could define a 64bit "de" variant I suppose, but doesn't really make much sense just for this one case, and when we start to use the DSB for this stuff we'd also need another 64bit variant for that. Just easier to do 32bit always. While at it we can reorder stuff a bit so that we write the registers in order of increasing offset (more or less). Signed-off-by:

Break the dependency on i915_drv.h. Signed-off-by:
-
Jani Nikula authored
Avoid looking into the guts of struct drm_i915_private in headers. Again, converting an inline function to a macro is less than ideal, but avoids having to pull in i915_drv.h just for the to_i915() part. Signed-off-by:
-
Jani Nikula authored
It's not the ideal location, but a better alternative than i915_drv.h. The goal is to break the intel_display_types.h to i915_drv.h dependency. Signed-off-by:

Jani Nikula authored
This is far from ideal, but it reduces the i915_drv.h dependency from intel_display_types.h. Maybe in the future we'll need a better split. Signed-off-by:

gt_pm selftest calculates engine ticks cycles and wall time cycles by delta of respective engine elapsed TIMESTAMP and ktime for period of 1000us. It compares the engine ticks cycles with wall time cycles. Disable local cpu interrupt so that interrupt handler does not switch out the thread during measure_clocks() and prevent miscalculation of engine tick cycles. v2: - nuke preempt_{disable,enable}, as disable_local_irq() disable the preemption.

This workaround is documented a bit strangely in the bspec; it's listed as an A0 workaround, but the description clarifies that the workaround is implicitly handled by the hardware and what the driver really needs to do is program a chicken bit to reenable some internal behavior. Signed-off-by:

Commit cd0fcf5a ("drm/i915: rename DISP_STEPPING->DISPLAY_STEP and GT_STEPPING->GT_STEP") renamed all platforms' display stepping tests, but the DG2 patches were still in-flight at that time and did not incorporate the new naming scheme.

PLANE_CUS_CTL has a restriction of 4096 width even though PLANE_SIZE and scaler size registers supports max 5120. Take care of this restriction in max_width. Without this patch, when 5k content is sent on HDR plane with NV12 content, FIFO underrun is seen and screen blanks out. v2: Addressed review comments from Ville. Added separate functions for max_width - for HDR and SDR v3: Addressed review comments from Ville. Changed names of HDR and SDR max_width functions to icl_hdr_plane_max_width and icl_sdr_plane_max_width v4: Fixed paranthesis alignment. No code change Reviewed-by:

While working on supporting the Intel HDR backlight interface, I noticed that there's a couple of laptops that will very rarely manage to boot up without detecting Intel HDR backlight support - even though it's supported on the system. One example of such a laptop is the Lenovo P17 1st generation. Following some investigation Ville Syrjälä did through the docs they have available to them, they discovered that there's actually supposed to be a 30ms wait after writing the source OUI before we begin setting up the rest of the backlight interface. This seems to be correct, as adding this 30ms delay seems to have completely fixed the probing issues I was previously seeing. So - let's start performing a 30ms wait after writing the OUI, which we do in a manner similar to how we keep track of PPS delays (e.g. record the timestamp of the OUI write, and then wait for however many ms are left since that timestamp right before we interact with the backlight) in order to avoid waiting any longer then we need to. As well, this also avoids us performing this delay on systems where we don't end up using the HDR backlight interface. V3: * Move last_oui_write into intel_dp V2: * Move panel delays into intel_pps Signed-off-by:
