Hello again, hope you are still reading my texts...
I digged through the code and narrowed down the issue I wanted to fix.
It appears to be related to the `bool thermal_active` dpm struct
member and this piece of code:
if (rdev->asic->dpm.force_performance_level) {
if (rdev->pm.dpm.therma
ith R600_DEBUG=help).
Anyway, this is probably related to comment #3.

--- Comment #31 from KernelBug <3fdd1e5d at opayq.com> ---
I wonder if any of the developers are aware that there is not one distro this
works on? Meaning there isn't the support for it in Linux, which I was hoping
was going to come from the kernel

MIPI_DSI_MODE_NON_CONTINUOUS is exactly the flag that devices need to
set to signal that they support non-continuous mode. If devices don't
have that set, then the controller should always provide the HS clock.
So, if MIPI_DSI_MODE_NON_CONTINUOUS is *not* set, then the peripheral
does *not* support non-continuous mode.

is to be sent in low-power
mode.
With the above two flags we can cover four cases:
1) non-continuous mode with messages transmitted in low-power mode
2) non-continuous mode with messages transmitted in high-speed mode
3) continuous mode with messages transmitted in low-power mode
4) continuous mode with messages transmitted in high-speed mode
What other cases do you think we need to support?

Yes, if the MIPI_DSI_MODE_NON_CONTINUOUS flag is not specified, then it
means the peripheral supports only continuous mode.

there is some hardware than can do 2D compositing with an arbitrary
