GVT currently relies on display internals through register macros and helpers
like for_each_pipe(). This tight coupling makes modularization difficult
because GVT should not access struct intel_display directly.
Add an API for GVT code to expose DISPLAY_RUNTIME_INFO()->pipe_mask.
This series introduces changes to make GVT independent of display internals
while keeping existing macros usable:
- Abstract offset calculations in display using
INTEL_DISPLAY_DEVICE_*_OFFSET() macros.
- Add APIs for GVT to compute offsets and pipe mask via functions.
- Update GVT to use these APIs by overriding helper macros and
for_each_pipe().
Ankit Nautiyal (5):
drm/i915/display: Abstract pipe/trans/cursor offset calculation
drm/i915/display: Add APIs to be used by gvt to get the register
offsets
drm/i915/gvt: Add header to use display offset functions in macros
drm/i915/gvt: Change for_each_pipe to use pipe_mask API
drm/i915/gvt/display_helpers: Cast argument to enum pipe for
pipe-offset macro
