drm/rockchip: Replace custom wait_for_vblanks with helper · 81c248f7

由 Tomasz Figa 提交于 9月 14, 2016

Currently the driver uses a custom function to wait for flip to complete
after an atomic commit. It was needed before because of two problems:
 - there is no hardware vblank counter, so the original helper would
   have a race condition with the vblank interrupt,
 - the driver didn't support unreferencing cursor framebuffers
   asynchronously to the commit, which was what the helper expected.
Since both problems have been solved by previous patches, we can now
make the driver use the generic helper and remove custom waiting code.

drm/rockchip: Unreference framebuffers from flip work · 47a7eb45

由 Tomasz Figa 提交于 9月 14, 2016

Currently the driver waits for vblank and then unreferences old
framebuffers from atomic commit code path. This is however breaking the
legacy cursor API, which requires the updates to be fully asynchronous.
Instead of just adding a special case for cursor, we can have actually
smaller amount of code to unreference any changed framebuffer from a
flip work.

drm/rockchip: Avoid race with vblank count increment · 7caecdbe

由 Tomasz Figa 提交于 9月 14, 2016

Since VOP does not have a hardware vblank count register, the ongoing
commit might be racing with a requested vblank interrupt, which would
increment the software vblank counter before the changes being committed
actually happen.

To avoid this, we can extend .atomic_flush(), so after it sets cfg_done
bit, it polls the vblank interrupt bit until it's inactive to make sure
that any old vblank interrupt gets to the handler and then uses
synchronize_irq(vop->irq) to make sure the handler finishes running.

The polling case should happen very rarely, but even if, the total wait
time should be relatively low and in practice almost equal to the vop
hardirq handler running time.

drm/rockchip: Get rid of some unnecessary code · 65bcb6bc

由 Tomasz Figa 提交于 9月 14, 2016

Current code implements prepare_fb and cleanup_fb callbacks only to
grab/release fb references, which is already done by atomic framework
when creating/destryoing plane state. Let's remove these
unused bits.

drm/rockchip: Clear interrupt status bits before enabling · fa374107

由 Tomasz Figa 提交于 9月 14, 2016

The enable register only masks the raw status bits to signal CPU
interrupt only for enabled interrupts. The status bits are activated
regardless of the enable register. This means that we might have an old
interrupt event queued, which we are not interested in. To avoid getting
a spurious interrupt signalled, we have to clear the old bit before we
update the enable register.

drm/bridge: analogix_dp: Remove duplicated code · d2f12adc

由 Tomeu Vizoso 提交于 8月 05, 2016

Remove code for reading the EDID and DPCD fields and use the helpers
instead.

Besides the obvious code reduction, other helpers are being added to the
core that could be used in this driver and will be good to be able to
use them instead of duplicating them.

drm/rockchip: Don't key off vblank for psr · b883c9ba

由 Sean Paul 提交于 8月 18, 2016

Instead of keying off vblank for psr, just flush every time
we get an atomic update. This ensures that cursor updates
will properly disable psr (without turning vblank on/off),
and unifies the paths between fb_dirty and atomic psr
enable/disable.
