2015-01-25drm/exynos: rename base object of struct exynos_drm_crtc to 'base'Gustavo Padovan2-6/+5
'base' is more widely used name in the drm subsystem for the base object. Signed-off-by: Gustavo Padovan <[email protected]> Signed-off-by: Inki Dae <[email protected]>
2015-01-25drm/exynos: remove exynos_drm_crtc_mode_set_commit()Gustavo Padovan1-7/+1
This was just as extra chain in the call stack. We just rename it to _set_base() and let it do everything alone. Signed-off-by: Gustavo Padovan <[email protected]> Signed-off-by: Inki Dae <[email protected]>
2015-01-25drm/exynos: call exynos_update_plane() directly on page flipsGustavo Padovan1-2/+6
Avoid an extra call to exynos_drm_crtc_mode_set_commit() that only calls exynos_update_plane(). Signed-off-by: Gustavo Padovan <[email protected]> Signed-off-by: Inki Dae <[email protected]>
2015-01-25drm/exynos: unify plane update on exynos_update_plane()Gustavo Padovan3-16/+8
We can safely use the exynos_update_plane() to update the plane framebuffer for both the overlay and primary planes. Note that this patch removes a call to manager->ops->commit() in exynos_drm_crtc_mode_set_commit(). The commit() call is used only by the fimd driver to set underlying timings and need only in full modeset operations. For plane update only win_commit is needed.

2015-01-25drm/exynos: remove exynos_plane_commit() wrapperGustavo Padovan3-12/+8
It's doing nothing but calling exynos_crtc->ops->win_commit(), so let's call this directly to avoid extra layers of abstraction. Signed-off-by: Gustavo Padovan <[email protected]> Signed-off-by: Inki Dae <[email protected]>
2015-01-25drm/exynos: don't do any DPMS operation while updating planesGustavo Padovan1-1/+7
DPMS only makes sense when the mode changes, for plane update changes do not perform any dpms operation. This move places the win_commit() and commit() calls directly in the code instead of calling exynos_drm_crtc_commit() thus avoiding DPMS operations. Signed-off-by: Gustavo Padovan <[email protected]> Signed-off-by: Inki Dae <[email protected]>
2015-01-25drm/exynos: Don't touch DPMS when updating overlay planesGustavo Padovan1-1/+0
DPMS settings should only be changed by a full modeset. exynos_plane_update() should only care about updating the planes itself and nothing else. Signed-off-by: Gustavo Padovan <[email protected]> Signed-off-by: Inki Dae <[email protected]>

2015-01-25drm/exynos: remove struct exynos_drm_overlayGustavo Padovan6-117/+112
struct exynos_drm_overlay has no practical advantage nor serves as important piece of the exynos API design. The only place it was used was inside the struct exynos_plane which was just causing a extra access overhead. Users had to access the overlay first and just then get the plane information it contains. This patch merges struct exynos_drm_overlay into struct exynos_plane. It also renames struct exynos_plane to struct exynos_drm_plane. The rational is to cut one step to access plane information.

2015-01-25drm/exynos: expose struct exynos_drm_crtcGustavo Padovan2-30/+30
Let other pieces of the driver access struct exynos_drm_crtc as well. struct exynos_drm_manager will be merged into struct exynos_drm_crtc, in the sense we will move all its members to exynos_drm_crtc, so to start this conversion exynos_drm_crtc need to be exposed as well.

2015-01-23dm cache: fix problematic dual use of a single migration count variableJoe Thornber1-39/+50
Introduce a new variable to count the number of allocated migration structures. The existing variable cache->nr_migrations became overloaded. It was used to: i) track of the number of migrations in flight for the purposes of quiescing during suspend. ii) to estimate the amount of background IO occuring. Recent discard changes meant that REQ_DISCARD bios are processed with a migration. Discards are not background IO so nr_migrations was not incremented. However this could cause quiescing to complete early. (i) is now handled with a new variable cache->nr_allocated_migrations. cache->nr_migrations has been renamed cache->nr_io_migrations. cleanup_migration() is now called free_io_migration(), since it decrements that variable. Also, remove the unused cache->next_migration variable that got replaced with with prealloc_structs a while ago.

2015-01-23dm cache: share cache-metadata object across inactive and active DM tablesJoe Thornber1-6/+95
If a DM table is reloaded with an inactive table when the device is not suspended (normal procedure for LVM2), then there will be two dm-bufio objects that can diverge. This can lead to a situation where the inactive table uses bufio to read metadata at the same time the active table writes metadata -- resulting in the inactive table having stale metadata buffers once it is promoted to the active table slot. Fix this by using reference counting and a global list of cache metadata objects to ensure there is only one metadata object per metadata device.

2015-01-23gpu: host1x: Call host1x_device_add() under lockThierry Reding1-4/+2
Instead of locking within host1x_device_add(), call it under the lock to make the locking more consistent. Signed-off-by: Thierry Reding <[email protected]>
2015-01-23gpu: host1x: Call ->remove() only when a device is boundThierry Reding2-2/+9
When a driver's ->probe() function fails, the host1x bus must not call its ->remove() function because the driver will already have cleaned up in the error handling path in ->probe(). Signed-off-by: Thierry Reding <[email protected]>
