This is no longer used anywhere and so can be removed. However, tracking the dirty status on the ppgtt doesn't work very well if the ppgtt is shared, so perhaps for the best that it is no longer required. Signed-off-by:

The differences are only on the pins, trigger and long_detect function. The MCC handling is already partially merged, so merge TGP as well. Remove the pins argument from icp_irq_handler() so we have all the differences between the 3 set in a common if ladder. Signed-off-by:

South, follow the north. Instead of defining separate macros for each port, make them take port as parameter as done for TC ports and for north engine. This will allow us to easily extend this as needed. tgp_ddi_port_hotplug_long_detect() is also removed as after the EHL introduction the tgp variant is an exact copy of icp. Signed-off-by:

The addition of the DC_FLUSH failed to ensure sanctity of the post-sync write as CI immediately got a completion CS-event before the breadcrumb was coherent. So let's try the other idea of moving the post-sync write into the CS_STALL.

During normal driver unload we attempt to disable GuC communication while it is currently stopped. This results in a nop'd call to intel_guc_ct_disable within guc_disable_communication because stop/disable rely on the same flag to prevent further comms with CT. We can avoid the call to disable and still leave communication in a satisfactory state by extracting a set of shared steps from stop/disable. This set can include guc_disable_interrupts as we do not require the single caller of guc_stop_communication to be atomic: "drm/i915/selftests: Fixup atomic reset checking". This situation (stop -> disable) only occurs during intel_uc_fini_hw, so during fini, call guc_disable_communication only if currently enabled. The symmetric calls to enable/disable remain unmodified for all other scenarios. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110943Signed-off-by:

There is a difference in BSpec's and the driver's designation of DDI ports. BSpec uses the following names: - before GEN11: BSpec/driver: port A/B/C/D etc - GEN11: BSpec/driver: port A-F - GEN12: BSpec: port A/B/C for combo PHY ports port TC1-6 for Type C PHY ports driver: port A-I. The driver's port D name matches BSpec's TC1 port name. So far power domains were named according to the BSpec designation, to make it easier to match the code against the specification. That however can be confusing when a power domain needs to be matched to a port on GEN12+. To resolve that use the driver's port A-I designation for power domain names too and rename the corresponding power wells so that they reflect the mapping from the driver's to BSpec's port name.

We've been ignoring similar coherency issues in IGT for Broadwater, and specifically Broadwater (original gen4) and not, for example, Crestline (same generation as Broadwater, but the mobile variant). Without any means to reproduce locally (I have a 965GM but alas no 965G), fixing will be slow, so tell CI to ignore any failure until we are ready with a fix. Signed-off-by:

Quite rarely we see that the CS completion event fires before the breadcrumb is coherent, which presumably is a result of the CS_STALL not waiting for the post-sync operation. Try throwing in a DC_FLUSH into the following pipecontrol to see if that makes any difference. Signed-off-by:

Upon object creation for live_gem_contexts, we fill the object with known scratch and flush it out of the CPU cache. Before performing the GPU fill, we don't need to flush it again and so avoid serialising with previous fills. However, we do need some throttling on the internal interfaces if we do not want to run out of memory! Signed-off-by:

Daniele Ceraolo Spurio authored
The CS pre-parser can pre-fetch commands across memory sync points and starting from gen12 it is able to pre-fetch across BB_START and BB_END boundaries as well, so when we emit gpu relocs the pre-parser might fetch the target location of the reloc before the memory write lands. The parser can't pre-fetch across the ctx switch, so we use a separate context to guarantee that the memory is synchronized before the parser can get to it. Note that there is no risk of the CS doing a lite restore from the reloc context to the user context, even if the two have the same hw_id, because since gen11 the CS also checks the LRCA when deciding if it can lite-restore. v2: limit new context to gen12+, release in eb_destroy, add a comment in emit_fini_breadcrumb (Chris).

On TGL some registers moved from DDI to transcoder and the DisplayPort training sequence has a separate BSpec page. I started adding 'ifs' to the original intel_ddi_pre_enable_dp() but it was becoming really hard to follow, so a new and cleaner function for TGL was added with comments of all steps. It's similar to ICL, but different enough to deserve a new function. The rest of DisplayPort enable and the whole disable sequences remained the same. v2: FEC and DSC should be enabled on sink side before start link training(Maarten reported and Manasi confirmed the DSC part) v3: Add call to enable FEC on step 7.l(Manasi) BSpec: 49190 Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Manasi Navare <manasi.d.navare@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

On TGL+ it's possible to have PSR1 enabled in other ports besides DDIA. PSR2 is still limited to DDIA. However currently we handle only one instance of PSR struct. Lets guard intel_psr_init_dpcd() against multiple eDP panels and warn about it. v2: Reword commit message to be TGL+ only and with the info where PSR1/PSR2 are supported (Lucas) Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by:
