[3.16-rcX][pciehp][radeon] PCIe HotPlug conflicts with radeon GPU
From: Shawn Starr
Date: Sat Aug 02 2014 - 12:09:35 EST
Hello devs,
There are two issues I am encountering with the PCIe Hotplug driver on my Lenovo Laptop (W500). I note this goes back further than 3.15.
It is noted here:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f244d8b623dae7a7bc695b0336f67729b95a9736
https://bugzilla.kernel.org/show_bug.cgi?id=79701
And my open bug here:
https://bugzilla.kernel.org/show_bug.cgi?id=77261
1) If I enable the device to use both the integrated and discrete GPU, pciehp will decide to force unload radeon because it puts itself into a power saving state, fails back to the Intel integrated GPU in this case unless I tell radeon.ko to runpm=0 (no power management, then pciehp wont touch it).
2) If the Radeon GPU resets and you use pci_reset=1 for kernel module option, pciehp decides to force unload radeon even though the GPU is trying to setup after failing.
Kernel I am using right now: 3.16.0-0.rc7.git3.1.fc21.x86_64 (about to boot into snapshot kernel-core-3.16.0-0.rc7.git4.1.fc21.x86_64)
Here is kernel dump (from time GPU resets, and cascading failure with PCIe Hotplug fighting):
