In order for hibernation to reliably work we need to properly turn off the SDMA block, sadly after numerous attemps i haven't not found proper sequence for clean and full shutdown. So simply reset both SDMA block, this makes hibernation works reliably on sea island GPU family (CI) Hibernation and suspend to ram were tested (several times) on : Bonaire Hawaii Mullins Kaveri Kabini Cc: stable@vger.kernel.org Signed-off-by:

In order for hibernation to reliably work we need to cleanup more thoroughly the compute ring. Hibernation is different from suspend resume as when we resume from hibernation the hardware is first fully initialize by regular kernel then freeze callback happens (which correspond to a suspend inside the radeon kernel driver) and turn off each of the block. It turns out we were not cleanly shutting down the compute ring. This patch fix that. Hibernation and suspend to ram were tested (several times) on : Bonaire Hawaii Mullins Kaveri Kabini Changed since v1: - Factor the ring stop logic into a function taking ring as arg.

On the MacBook Pro, power of the gpu is cut by a gmux chip. Sometimes the gpu gets stuck in powersaving mode and refuses to wake up ("Refused to change power state, currently in D3"). Inserting a delay between setting the gpu to D3hot and cutting the power seems to help (most of the time). This issue and its (partial) remediation by the patch was observed with an Nvidia GT650M (NVE7 / GK107). Signed-off-by:Lukas Wunner <lukas@wunner.de> Signed-off-by:

I've only seen this once, and I failed to capture the lockdep backtrace, but I did some investigations. If we are calling into the MST layer from EDID probing, we have the mode_config mutex held, if during that EDID probing, the MST hub goes away, then we can get a deadlock where the connector destruction function in the driver tries to retake the mode config mutex. This offloads connector destruction to a workqueue, and avoid the subsequenct lock ordering issue. Acked-by:

ENWIN_F field of WINCONx register enables or disable a dma channel to each hardware overlay - the value of the field will be updated to real register after vsync.
