Instead of every new platform having yet another masive copy of the whole PLL sanitation code, let's just reuse the .disable_clock() hook for this purpose. We do need to plug this into the ICL+ DSI code for that, but fortunately it already has a suitable function we can use. We do lose the debug message though on account of not bothering to check if the clock is actually enabled or not before turning it off. We could introduce yet another vfunc to query the current state, but not sure it's worth the hassle?

The other DDI .enable_clock() functions are trying to protect us against pll==NULL. A bit tempted to throw out all the WARNs as just unnecessary noise, but I guess they might have some use when poking around the shared_dpll code (not sure it wouldn't oops elsewhere though). So let's unify it all and sprinkle in the missing WARNs for icl/dg1.

The current code attempts to protect the RMWs into global clock routing registers with a mutex, but forgets to do so in a few places. Let's remedy that. Note that at the moment we serialize all modesets onto single wq, so this shouldn't actually matter. But maybe one day we wish to attempt parallel modesets again...

For ICL+ we have several styles of clock routing for DDIs: 1) TC DDI + TC PHY -> needs DDI_CLK_SEL==MG/TBT part form intel_ddi_clk_{select,disable}() and ICL_DPCLKA_CFGCR0_TC_CLK_OFF part form icl_{map,unmap}_plls_to_ports() 2) ICL/TGL combo DDI + combo PHY -> just need the stuff from icl_{map,unmap}_plls_to_ports() 3) JSL/EHL TC DDI + combo PHY -> needs DDI_CLK_SEL==MG part from intel_ddi_clk_{select,disable}() and the full combo style clock selection from icl_{map,unmap}_plls_to_ports() 4) ADLS/RKL -> these use both TC and combo DDIs with combo PHYs, however they always use the full combo style clock selection as per icl_{map,unmap}_plls_to_ports() and do not use DDI_CLK_SEL at all, thus get treated the same as 2) We extract all that from the current mess in the following way: 1) icl_ddi_tc_{enable,disable}_clock() 2) icl_ddi_combo_{enable,disable}_clock() 3) jsl_ddi_tc_{enable,disable}_clock() 4) for now we reuse icl_ddi_combo_{enable,disable}_clock() here v2: s/dev_priv/i915/ (Lucas) Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210205214634.19341-8-ville.syrjala@linux.intel.com

intel_gt_driver_register() may be called earlier than intel_opregion_register() and acpi_video_register(), so move it up. intel_display_debugfs_register() may be called later, together with the other display-related initializations. There is a slight change in behavior that sysfs files will show up before the display-related debugfs files, but that shouldn't be a problem - userspace shouldn't be relying in debugfs. This allows us to group all the display-related calls under a single check for "HAS_DISPLAY()" that can be later moved to a better place.

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.

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.

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.
