In rare circumstances bugs in PCI programming, broken BIOS, or failing hardware can cause the CPU to lose access to the MMIO BAR on dgfx platforms. This is a pretty catastrophic failure since all register reads come back with values of 0xFFFFFFFF. Let's check for this special case while doing our usual checks for unclaimed registers; the FPGA_DBG register we use for those checks on modern platforms has some unused bits that will always read back as 0 when things are behaving properly; we can use them as canaries to detect when MMIO itself has suddenly broken and try to print a more informative error message in the logs. v2: Let the detection function still return 'true' if we've lost our MMIO access. We'll still get an extra false positive message about an unclaimed register access, but we'll still honor the 'mmio_debug' limit and not spam the log.

Although the bspec's description doesn't make it very clear, the hardware architects have confirmed that the FPGA_DBG register that we use to check for unclaimed MMIO accesses is display-specific and will only properly flag unclaimed MMIO transactions for registers in the display range. If a platform doesn't have display, FPGA_DBG itself will not be available and should not be checked. Let's move the feature flag into intel_device_info.display to more accurately reflect this. Given that we now know FPGA_DBG is display-specific, it could be argued that we should only check it on out intel_de_*() functions. However let's not make that change right now; keeping the checks in all of the existing locations still helps us catch cases where regular intel_uncore_*() functions use bad MMIO offset math / base addresses and accidentally wind up landing within an unused area within the display MMIO range. It will also help catch cases where userspace-initiated MMIO (e.g., IGT's intel_reg tool) attempt to read bad offsets within the display range. v2: Add missing hunk with the update to the HAS_FPGA_DBG_UNCLAIMED macro.

Apparently the new gen9_bc platforms that Intel has introduced don't provide us with a STRAP config register to read from for initializing DDI B, C, and D detection. So, workaround this by hard-coding our strap config in intel_setup_outputs().

Next, let's start introducing the HPD pin mappings for Intel's new gen9_bc platform in order to make hotplugging display connectors work. Since gen9_bc is just a TGP PCH along with a CML CPU, except with the same HPD mappings as ICL, we simply add a skl_hpd_pin function that is shared between gen9 and gen9_bc which handles both the traditional gen9 HPD pin mappings and the Icelake HPD pin mappings that gen9_bc uses. Changes since v4: * Split this into its own commit * Introduce skl_hpd_pin() like vsyrjala suggested and use that instead of sticking our HPD pin mappings in TGP code Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> [originally from Tejas's work] Signed-off-by:

With the introduction of gen9_bc, where Intel combines Cometlake CPUs with a Tigerpoint PCH, we'll need to introduce new DDC pin mappings for this platform in order to make all of the display connectors work.

Let's scream if we are about to release a frontbuffer which is still in use. Signed-off-by:
Chris Wilson <chris@chris-wilson.co.uk>

Ville Syrjälä authored
We don't have a persistent fb holding a reference to the frontbuffer object, so every time we do the get+put we throw the frontbuffer object immediately away. And so the next time around we get a pristine frontbuffer object with bits==0 even for the old vma. This confuses the frontbuffer tracking code which understandably expects the old frontbuffer to have the overlay's bit set. Fix this by hanging on to the frontbuffer reference until the next flip. And just to make this a bit more clear let's track the frontbuffer explicitly instead of just grabbing it via the old vma.

ilk+ planes get notably unhappy when the plane x+w exceeds the stride. This wasn't a problem previously because we always aligned SURF to the closest tile boundary so the x offset never got particularly large. But now with async flips we have to align to 256KiB instead and thus this becomes a real issue. On ilk/snb/ivb it looks like the accesses just wrap early to the next tile row when scanout goes past the SURF+n*stride boundary, hsw/bdw suffer more heavily and start to underrun constantly. i965/g4x appear to be immune. vlv/chv I've not yet checked. Let's borrow another trick from the skl+ code and search backwards for a better SURF offset in the hopes of getting the x offset below the limit. IIRC when I ran into a similar issue on skl years ago it was causing the hardware to fall over pretty hard as well. And let's be consistent and include i965/g4x in the check as well, just in case I just got super lucky somehow when I wasn't able to reproduce the issue. Not that it really matters since we still use 4k SURF alignment for i965/g4x anyway.

The TypeC FIA can be powered down if the TC-COLD power state is allowed, so block the TC-COLD state when initializing the FIA. Note that this isn't needed on ICL where the FIA is never modular and which has no generic way to block TC-COLD (except for platforms with a legacy TypeC port and on those too only via these legacy ports, not via a DP-alt/TBT port).
