radeon_test_ring_sync() and radeon_test_ring_sync2() are never called in atomic context. They call mdelay() to busily wait, which is not necessary. mdelay() can be replaced with msleep(). This is found by a static analysis tool named DCNS written by myself. Signed-off-by:

Update job earlier with the scheduler it is supposed to be scheduled on. Otherwise we could incorrectly optimize dependencies when moving an entity from one scheduler to another. Signed-off-by:

[why] There is currently a dependency on the order in which tests are executed. This is because the non-relevant state info is being printed, which results in the output based on the state from the previous test. [how] Print DPP DTN log only if the pipe is enabled. In addition to the affected per-submission DTN golden logs, included in this change is also DTN golden log update for pre-submission tests. The other DTN golden logs affected by this change will be updated upon nightly test run (which will generate the updated DTN logs). Signed-off-by:

[Why] If the hardware supports DFS bypass it will always be enabled after creation of the DCCG. DFS bypass should only be enabled when the current stream consists of a single embedded panel and the minimum display clock is below the DFS bypass threshold. [How] Add a function to the DCCG table that updates the DFS bypass state when setting the bandwidth. If the DFS bypass state is changed, the clock needs to be reprogrammed to reflect this before the DPREFCLK is updated for audio endpoints. The existing display clock value is used as the target display clock value when reprogramming since the resulting change will be equal or larger to the current value. These changes only specifically target dce110 but do offer a framework for support on other applicable targets. Signed-off-by:

[Why] We explicitly disable DFS bypass support when creating DC. Support for this feature should now be in place so it can be left implicitly enabled. [How] Remove the line that disables DFS bypass support. Note: This option was actually reset to false anyway for most of the hardware I've tested on making this particular line misleading in the first place. This patch also fixes this issue.

[Why] While there is support for using and quering DFS bypass clocks the hardware is never notified to enter DFS bypass mode for dce110. [How] Add a flag that can be set when programming the display engine PLL to enable DFS bypass mode. If this flag is set then the hardware is notified to enter DFS bypass mode and the correct display engine clock frequency can be acquired. Signed-off-by:

This is the first attempt to move entities between schedulers to have dynamic load balancing. We just move entities with no jobs for now as moving the ones with jobs will lead to other compilcations like ensuring that the other scheduler does not remove a job from the current entity while we are moving. v2: remove unused variable and an unecessary check Signed-off-by:
