2021-06-08drm/bridge: ti-sn65dsi83: Add TI SN65DSI83 and SN65DSI84 driverMarek Vasut3-0/+720
Add driver for TI SN65DSI83 Single-link DSI to Single-link LVDS bridge and TI SN65DSI84 Single-link DSI to Dual-link or 2x Single-link LVDS bridge. TI SN65DSI85 is unsupported due to lack of hardware to test on, but easy to add. The driver operates the chip via I2C bus. Currently the LVDS clock are always derived from DSI clock lane, which is the usual mode of operation. Support for clock from external oscillator is not implemented, but it is easy to add if ever needed. Only RGB888 pixel format is implemented, the LVDS666 is not supported, but could be added if needed.

2021-06-07drm/ttm, drm/amdgpu: Allow the driver some control over swappingThomas Hellström2-16/+34
We are calling the eviction_valuable driver callback at eviction time to determine whether we actually can evict a buffer object. The upcoming i915 TTM backend needs the same functionality for swapout, and that might actually be beneficial to other drivers as well. Add an eviction_valuable call also in the swapout path. Try to keep the current behaviour for all drivers by returning true if the buffer object is already in the TTM_PL_SYSTEM placement. We change behaviour for the case where a buffer object is in a TT backed placement when swapped out, in which case the drivers normal eviction_valuable path is run.

If the bo is idle when calling ttm_bo_pipeline_gutting(), we unnecessarily create a ghost object and push it out to delayed destroy. Fix this by adding a path for idle, and document the function.

2021-06-07drm: Add a prefetching memcpy_from_wcThomas Hellström4-2/+159
Reading out of write-combining mapped memory is typically very slow since the CPU doesn't prefetch. However some archs have special instructions to do this. So add a best-effort memcpy_from_wc taking dma-buf-map pointer arguments that attempts to use a fast prefetching memcpy and otherwise falls back to ordinary memcopies, taking the iomem tagging into account. The code is largely copied from i915_memcpy_from_wc.

2021-06-07drm/ttm: Add a generic TTM memcpy move for page-based iomemThomas Hellström9-181/+539
The internal ttm_bo_util memcpy uses ioremap functionality, and while it probably might be possible to use it for copying in- and out of sglist represented io memory, using io_mem_reserve() / io_mem_free() callbacks, that would cause problems with fault(). Instead, implement a method mapping page-by-page using kmap_local() semantics. As an additional benefit we then avoid the occasional global TLB flushes of ioremap() and consuming ioremap space, elimination of a critical point of failure and with a slight change of semantics we could also push the memcpy out async for testing and async driver development purposes. A special linear iomem iterator is introduced internally to mimic the old ioremap behaviour for code-paths that can't immediately be ported over. This adds to the code size and should be considered a temporary solution. Looking at the code we have a lot of checks for iomap tagged pointers. Ideally we should extend the core memremap functions to also accept uncached memory and kmap_local functionality. Then we could strip a lot of code.

2021-06-07drm/sun4i: de3: Be explicit about supported modifiersPiotr Oniszczuk2-2/+13
Currently only linear formats are supported in sun4i-drm driver, but SoCs like H6 supports AFBC variant of some of them in multiple cores (GPU, VPU, DE3). Panfrost already implements AFBC compression and is sometimes confused what should be default choice (linear, AFBC) if DRM driver is not explicit about modifier support (MiniMyth2 distro with MythTV app). After some discussion with Daniel Stone on #panfrost IRC, it was decided to make modifiers in sun4i-drm explicit, to avoid any kind of guessing, not just in panfrost, but everywhere. In fact, long term idea is to make modifier parameter in drm_universal_plane_init() mandatory (non NULL).

2021-06-04drm/panfrost: Add AFBC_FEATURES parameterAlyssa Rosenzweig5-1/+7
The value of the AFBC_FEATURES register is required by userspace to determine AFBC support on Bifrost. A user on our IRC channel (#panfrost) reported a workload that raised a fault on one system's Mali G31 but worked flawlessly with another system's Mali G31. We determined the cause to be missing AFBC support on one vendor's Mali implementation -- it turns out AFBC is optional on Bifrost! Whether AFBC is supported or not is exposed in the AFBC_FEATURES register on Bifrost, which reads back as 0 on Midgard. A zero value indicates AFBC is fully supported, provided the architecture itself supports AFBC, allowing backwards-compatibility with Midgard. Bits 0 and 15 indicate that AFBC support is absent for texturing and rendering respectively. The user experiencing the fault reports that AFBC_FEATURES reads back 0x10001 on their system, confirming the architectural lack of AFBC. Userspace needs this parameter to know to disable AFBC on that chip, and perhaps others. v2: Fix typo from copy-paste fail. v3: Bump the UABI version.
