This series adds runtime pm support for host1x, gr2d and dc. It retains the current behaviour if CONFIG_PM_RUNTIME is not enabled. The gr2d clock is enabled when a new job is submitted and disabled when the work is done. Due to parent->child relations between host1x->gr2d, this scheme enables and disables host1x clock. For dc, the clocks are enabled in .probe and disabled in .remove via runtime pm instead of direct clock APIs. Mayuresh is unfortunately not available to continue with the series and hence I will continue working on the patches. Changes in v4: - Fixed initialisation clean up in host1x and gr2d drivers - Runtime pm support removal follows now the same convention as other Tegra drivers - Code shuffling to prevent unnecessary function prototypes - Removed unnecessary NULL pointer checks. - Rebased on top of 3.12-rc4 Changes in v3: - Rebased patches on top of 3.12-rc2 - Removed unnecessary #ifdefs - Added descriptions to commit messages - If runtime pm is disabled, the code calls suspend/resume functions for enabling/disabling the clocks instead of repeating the functions Arto Merilainen (1): drm/tegra: Fix gr2d initialisation clean up Mayuresh Kulkarni (4): gpu: host1x: shuffle job APIs drm/tegra: Add runtime pm support for gr2d drm/tegra: Add runtime pm support for dc gpu: host1x: Add runtime pm support for host1x drivers/gpu/host1x/cdma.c | 2 ++ drivers/gpu/host1x/channel.c | 8 ----- drivers/gpu/host1x/channel.h | 1 - drivers/gpu/host1x/dev.c | 56 +++++++++++++++++++++++++++++----- drivers/gpu/host1x/drm/dc.c | 59 ++++++++++++++++++++++++++++++----- drivers/gpu/host1x/drm/gr2d.c | 71 ++++++++++++++++++++++++++++++++++++------- drivers/gpu/host1x/job.c | 13 ++++++++ drivers/gpu/host1x/job.h | 3 ++ 8 files changed, 177 insertions(+), 36 deletions(-) -- 1.8.1.5 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
