2023-02-18drm/i915: s/PIPECONF/TRANSCONF/Ville Syrjälä1-8/+8
Rename PIPECONF to TRANSCONF to make it clear what it actually applies to. While the usual convention is to pick the earliers name I think in this case it's more clear to use the later name. Especially as even the register offset is in the wrong range (0x70000 vs. 0x60000) and thus makes it look like this is per-pipe. There is one place in gvt that's doing something with TRANSCONF while iterating with for_each_pipe(). So that might not be doing the right thing for TRANSCODER_EDP, dunno. Not knowing what it does I left it as is to avoid breakage.

2023-01-25drm/i915/display: add intel_display_limits.h for key enumsJani Nikula1-0/+1
Move a handful of key enums to a new file intel_display_limits.h. These are the enum types, and the MAX/NUM enumerations within them, that are used in other headers. Otherwise, there's no common theme between them. Replace intel_display.h include with intel_display_limit.h where relevant, and add the intel_display.h include directly in the .c files where needed. Since intel_display.h is used almost everywhere in display/, include it from intel_display_types.h to avoid massive changes across the board. There are very few files that would need intel_display_types.h but not intel_display.h so this is neglible, and further cleanup between these headers can be left for the future. Overall this change drops the direct and indirect dependencies on intel_display.h from about 300 to about 100 compilation units, because we can drop the include from i915_drv.h.

2022-02-02drm/i915: Only include i915_reg.h from .c filesMatt Roper1-0/+1
Several of our i915 header files, have been including i915_reg.h. This means that any change to i915_reg.h will trigger a full rebuild of pretty much every file of the driver, even those that don't have any kind of register access. Let's delete the i915_reg.h include from all headers and add an explicit include from the .c files that truly need the register definitions; those that need a definition of i915_reg_t for a function definition can get it from i915_reg_defs.h instead. We also remove two non-register #define's (VLV_DISPLAY_BASE and GEN12_SFC_DONE_MAX) into i915_reg_defs.h to allow us to drop the i915_reg.h include from a couple of headers. There's probably a lot more header dependency optimization possible, but the changes here roughly cut the number of files compiled after 'touch i915_reg.h' in half --- a good first step.

2021-03-01drm/i915/gvt: Refactor GVT vblank emulator for vGPU virtual displayColin Xu1-48/+57
Current vblank emulator uses single hrtimer at 16ms period for all vGPUs, which introduces three major issues: - 16ms matches the refresh rate at 62.5Hz (instead of 60Hz) which doesn't follow standard timing. This leads to some frame drop or glitch issue during video playback. SW expects a vsync interval of 16.667ms or higher precision for an accurate 60Hz refresh rate. However current vblank emulator only works at 16ms. - Doesn't respect the fact that with current virtual EDID timing set, not all resolutions are running at 60Hz. For example, current virtual EDID also supports refresh rate at 56Hz, 59.97Hz, 60Hz, 75Hz, etc. - Current vblank emulator use single hrtimer for all vGPUs. Regardsless the possibility that different guests could run in different resolutions, all vsync interrupts are injected at 16ms interval with same hrtimer. Based on previous patch which decode guest expected refresh rate from vreg, the vblank emulator refactor patch makes following changes: - Change the vblank emulator hrtimer from gvt global to per-vGPU. By doing this, each vGPU display can operates at different refresh rates. Currently only one dislay is supported for each vGPU so per-vGPU hrtimer is enough. If multiple displays are supported per-vGPU in future, we can expand to per-PIPE further. - Change the fixed hrtimer period from 16ms to dynamic based on vreg. GVT is expected to emulate the HW as close as possible. So reflacting the accurate vsync interrupt interval is more correct than fixed 16ms. - Change the vblank timer period and start the timer on PIPECONF change. The initial period is updated to 16666667 based on 60Hz refresh rate. According to PRM, PIPECONF controls the timing generator of the connected display on this pipe, so it's safe to stop hrtimer on PIPECONF disabling, and re-start hrtimer at new period on enabling. Other changes including: - Move vblank_timer_fn from irq.c into display.c. - Clean per-vGPU vblank timer at clean_display instead of clean_irq. To run quick test, launch a web browser and goto URL: www.displayhz.com The actual refresh rate from guest can now always match guest settings. V2: Rebase to 5.11. Remove unused intel_gvt_clean_irq(). Simplify enable logic in update_vblank_emulation(). (zhenyu) Loop all vGPU by idr when check all vblank timer.

2021-03-01drm/i915/gvt: Get accurate vGPU virtual display refresh rate from vregColin Xu1-0/+2
Guest OS builds up its timing mode list based on the virtual EDID as simulated by GVT. However since there are several timings supported in the virtual EDID, and each timing can also support several modes (resolution and refresh rate), current emulated vblank period (16ms) may not always be correct and could lead to miss-sync behavior in guest. Guest driver will setup new resolution and program vregs accordingly and it should always follows GEN PRM. Based on the simulated display regs by GVT, it's safe to decode the actual refresh rate using by guest from vreg only. Current implementation only enables PIPE_A and PIPE_A is always tied to TRANSCODER_A in HW. GVT may simulate DP monitor on PORT_B or PORT_D based on the caller. So we can find out which DPLL is used by PORT_x which connected to TRANSCODER_A and calculate the DP bit rate from the DPLL frequency. Then DP stream clock (pixel clock) can be calculated from DP link M/N and DP bit rate. Finally, get the refresh rate from pixel clock, H total and V total. The per-vGPU accurate refresh rate is not used yet but only stored, until per-vGPU vblank timer is enabled. Then each vGPU can have different and accurate refresh rate per-guest driver configuration. Refer to PRM for GEN display and VESA timing standard for more details. V2: Rebase to 5.11. Correctly calculate DP link rate for BDW and BXT. Use GVT_DEFAULT_REFRESH_RATE instead of hardcoded to 60 as init refresh. Typo fix.

Init value of some display vregs rea inherited from host pregs. When host display in different status, i.e. all monitors unpluged, different display configurations, etc., GVT virtual display setup don't consistent thus may lead to guest driver consider display goes malfunctional. The added init vreg values are based on PRMs and fixed by calcuation from current configuration (only PIPE_A) and the virtual EDID.

2019-03-29drm/i915/gvt: Enable async flip on plane surface mmio writesColin Xu1-1/+0
According to Intel GFX PRM on 01.org, plane surface address can be updated synchronously or asynchronously. Synchronous flip will hold plane surface address update to start of next vsync, which is current implementation. Asynchronous flip will update the address as soon as possible. Without async flip, some 3D application could not reach better performance and the maximum performance is no higher than vsync frequency. The patch enables the async flip on plane surface address mmio update, and increment flip count correctly. With async flip enabled, some 3D applications have significant performance improvement. i.e. 3DMark Ice Storm has a 300%~400% increment on score. v2: Use bit operation definition for flip mode.
