From: Nicolin Chen <[email protected]>
Tegra241 CMDQV exposes per-VCMDQ register windows through two MMIO
apertures:
Direct VCMDQ aperture (0x10000/0x20000): VCMDQ Page0/Page1
VINTF logical aperture (0x30000/0x40000): VINTF0 LVCMDQ Page0/Page1
Both apertures are hardware aliases of the same underlying registers:
Page 0 (control/status): CONS_INDX, PROD_INDX, CONFIG, STATUS,
GERROR, GERRORN
Page 1 (base/DRAM): BASE_L/H, CONS_INDX_BASE_DRAM_L/H
The direct aperture Page 0 is programmable at any time so long as
CMDQV_EN is enabled. The VINTF (logical) aperture Page 0 is
programmable only once SW has mapped a VCMDQ to a VINTF; the
"logical" view is local to that VINTF.
Add read emulation for both apertures, backed by a single per-VCMDQ
register cache. VINTF aperture reads are translated to their
equivalent direct-aperture offset and served from the same cached
state.
Once IOMMU_HW_QUEUE_ALLOC and viommu_mmap are wired up in a
subsequent patch, Page 0 reads will be served directly from the
hardware-backed mmap'd page instead of the cache. Page 1 is also a
hardware alias, but the kernel only exposes mmap for Page 0, so
Page 1 reads always trap to QEMU and are served from cache.
