drm/radeon: Poll for both connect/disconnect on analog connectors

2016-08-20T16:10:59+00:00

commit 14ff8d48f2235295dfb3117693008e367b49cdb5 upstream. DRM_CONNECTOR_POLL_CONNECT only enables polling for connections, not disconnections. Because of this, we end up losing hotplug polling for analog connectors once they get connected. Easy way to reproduce: - Grab a machine with a radeon GPU and a VGA port - Plug a monitor into the VGA port, wait for it to update the connector from disconnected to connected - Disconnect the monitor on VGA, a hotplug event is never sent for the removal of the connector. Originally, only using DRM_CONNECTOR_POLL_CONNECT might have been a good idea since doing VGA polling can sometimes result in having to mess with the DAC voltages to figure out whether or not there's actually something there since VGA doesn't have HPD. Doing this would have the potential of showing visible artifacts on the screen every time we ran a poll while a VGA display was connected. Luckily, radeon_vga_detect() only resorts to this sort of polling if the poll is forced, and DRM's polling helper doesn't force it's polls. Additionally, this removes some assignments to connector->polled that weren't actually doing anything. Signed-off-by: Lyude Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/radeon: add a delay after ATPX dGPU power off

2016-08-20T16:10:59+00:00

commit d814b24fb74cb9797d70cb8053961447c5879a5c upstream. ATPX dGPU power control requires a 200ms delay between power off and on. This should fix dGPU failures on resume from power off.

drm/radeon: fix asic initialization for virtualized environments

2016-06-13T19:37:34+00:00

When executing in a PCI passthrough based virtuzliation environment, the hypervisor will usually attempt to send a PCIe bus reset signal to the ASIC when the VM reboots. In this scenario, the card is not correctly initialized, but we still consider it to be posted. Therefore, in a passthrough based environemnt we should always post the card to guarantee it is in a good state for driver initialization.

drm/radeon: do not hard reset GPU while freezing on r600/r700 family

2016-06-13T16:21:51+00:00

Seems r600/r700 does not like hard reset while freezing for hibernation (regression due to 274ad65c9d02bdcbee9bae045517864c3521d530 which itself is a fix for hibernation on some GPU families). Until i can debug further issue with r600, let just disable this for r600/r700 as they are very similar family and bug affecting one likely affect the other.
