There are a couple places in our driver that loop over transcoders A..D for gen11+; since RKL only has three pipes/transcoders, this can lead to unclaimed register reads/writes. We should add checks for transcoder existence where appropriate. v2: Move one transcoder check that wound up in the wrong function after conflict resolution. It belongs in bdw_get_trans_port_sync_config rather than bxt_get_dsi_transcoder_state. v3: Switch loops to use for_each_cpu_transcoder_masked() since this iterator already checks the platform's transcoder mask for us.

Replace the use of mode->private_flags with a truly private bitmaks in our own crtc state. We also need a copy in the crtc itself so the vblank code can get at it. We already have scanline_offset in there for a similar reason, as well as the vblank->hwmode which is assigned via drm_calc_timestamping_constants(). Fortunately we now have a nice place for doing the crtc_state->crtc copy in intel_crtc_update_active_timings() which gets called both for modesets and init/resume readout. The one slightly iffy spot is the INHERITED flag which we want to preserve until userspace/fb_helper does the first proper commit after actually calling .detecti() on the connectors. Otherwise we don't have the full sink capabilities (audio,infoframes,etc.) when .compute_config() gets called and thus we will fail to enable those features when the first userspace commit happens. The only internal commit we do prior to that should be from intel_initial_commit() and there we can simply preserve the INHERITED flag from the readout. v2: Deal with INHERITED in sanitize_watermarks() as well CC: Sam Ravnborg <sam@ravnborg.org> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: NDaniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200429103904.11727-1-ville.syrjala@linux.intel.com

RKL only has five universal planes, plus a cursor. Since the bottom-most universal plane is considered the primary plane, set the number of sprites available on this platform to 4. In general, the plane capabilities of the remaining planes stay the same as TGL. However the NV12 Y-plane support moves down to the new top two planes and now only the bottom three planes can be used for NV12 UV.

i915_irq.c is large. One reason for this is that has a large chunk of the GT render power management stashed away in it. Extract that logic out of i915_irq.c and intel_pm.c and put it under one roof. Based on a patch by Chris Wilson.

Split gen11_irq_handler() to receive as parameter the function pointers. This allows to share the interrupt handler even if the enable/disable functions are different. Make sure it's always inlined to avoid the extra indirect call on the hot path. Checking with gcc 9 this produce the exact same code as of now: $ size drivers/gpu/drm/i915/i915_irq*.o text data bss dec hex filename 47511 560 0 48071 bbc7 drivers/gpu/drm/i915/i915_irq.o 47511 560 0 48071 bbc7 drivers/gpu/drm/i915/i915_irq_new.o $ gdb -batch -ex 'file drivers/gpu/drm/i915/i915_irq.o' -ex 'disassemble gen11_irq_handler' > /tmp/old.s $ gdb -batch -ex 'file drivers/gpu/drm/i915/i915_irq_new.o' -ex 'disassemble gen11_irq_handler' > /tmp/new.s $ git diff --no-index /tmp/{old,new}.s $ So, no change in behavior, just a simple refactor.

Gen11+ has more hardware planes than gen9 so we need to test additional pipe interrupt register bits to recognize any GTT faults that happen on these extra planes.

Commit 2d6f6f35 ("drm/i915: add i915_driver_modeset_remove()") claimed removal of asymmetry in probe() and remove() calls, however, it didn't take care of calling intel_irq_uninstall() on driver remove. That doesn't hurt as long as we still call it from intel_modeset_driver_remove() but in order to have full symmetry we should call it again from i915_driver_modeset_remove(). Note that it's safe to call intel_irq_uninstall() twice thanks to commit b318b824 ("drm/i915: Nuke drm_driver irq vfuncs"). We may only want to mention the case we are adding in a related FIXME comment provided by that commit. While being at it, update the name of function mentioned as calling it out of sequence as that name has been changed meanwhile by commit 78dae1ac ("drm/i915: Propagate "_remove" function name suffix down").

The Jasper Lake PCH follows ICP/TGP's south display behavior and is identical to MCC graphics-wise except that it does not use the unusual (port C -> TC1) pin mapping that MCC does. Also, it turns out the extra PCH ID that we had previously thought was a form of MCC is actually a second ID for JSP (i.e., port C uses the port C pins instead of the TC1 pins). v2: - Also update the port masks (not just the pin table) in mcc_hpd_irq_setup. (Vivek) v3: - Break jsp_hpd_irq_setup out into its own function for clarity.

Avoid going to the base i915 device when we already have a path from gt to the runtime powermanagement interface. The benefit is that it looks a bit more self-consistent to always be acquiring the gt->uncore->rpm for use with the gt->uncore.

The current "disable C3+" workaround for the delayed vblank irqs on i945gm no longer works. I'm not sure what changed, but now I need to also disable C2. I also got my hands on a i915gm machine that suffers from the same issue. After some furious poking of registers I managed to find a better workaround: The "Do not Turn off Core Render Clock in C states" bit. With that I no longer have to disable any C-states, and as a nice bonus the power cost is only ~1/4 of the "disable C3+" method (which mind you doesn't even work anymore, and so would have an even higher power cost if we made it work by also disabling C2). So let's throw out all the cpuidle/qos crap and just toggle the magic bit as needed. And we extend the workaround to cover i915gm as well.
