gpu/radeon: Set flag to indicate broken 64-bit MSI

2014-12-06T23:57:33Z

commit 91ed6fd2c383bb8f02d66e98b4a4d2f7207249dc upstream. Some radeon ASICs don't support all 64 address bits of MSIs despite advertising support for 64-bit MSIs in their configuration space. This breaks on systems such as IBM POWER7/8, where 64-bit MSIs can be assigned with some of the high address bits set. This makes use of the newly introduced "no_64bit_msi" flag in structure pci_dev to allow the MSI allocation code to fallback to 32-bit MSIs on those adapters. Adding Alex's review tag. Patch to the driver is identical to the reviewed one, I dropped the arch/powerpc hunk rewrote the subject and cset comment.

drm/radeon: report disconnected for LVDS/eDP with PX if ddc fails

commit 1348579433566355e570008929daa09a0db64fd8 upstream. If ddc fails, presumably the i2c mux (and hopefully the signal mux) are switched to the other GPU so don't fetch the edid from the vbios so that the connector reports disconnected. bug: https://bugzilla.opensuse.org/show_bug.cgi?id=904417 Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/radeon: disable native backlight control on pre-r6xx asics (v2)

commit b7bc596ebbe0cddc97d76ef9309f64471bbf13eb upstream. Just use the acpi interface. That's what windows uses on this generation and it's the only thing that seems to work reliably on these generation parts.

drm/radeon: add locking around atombios scratch space usage

2014-11-21T17:23:11Z

commit 1c9498425453bb65ef339a57705c5ef59fe1541d upstream. While developing MST support I noticed I often got the wrong data back from a transaction, in a racy fashion. I noticed the scratch space wasn't locked against concurrent users. Based on a patch by Alex, but I've made it a bit more obvious when things are locked.
