2021-06-07drm/ttm: Document and optimize ttm_bo_pipeline_gutting()Thomas Hellström3-15/+72
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. Also avoid having the bo end up in a bad state vulnerable to user-space triggered kernel BUGs if the call to ttm_tt_create() fails. Finally reuse ttm_bo_pipeline_gutting() in ttm_bo_evict().

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).

If the of_get_named_gpio_flags call fails in vc4_hdmi_bind, we jump to the err_unprepare_hsm label. That label will then call pm_runtime_disable and put_device on the DDC device. We just retrieved the DDC device, so the latter is definitely justified. However at that point we still haven't called pm_runtime_enable, so the call to pm_runtime_disable is not supposed to be there.
