2013-08-07drm/radeon: make missing smc ucode non-fatalAlex Deucher
The smc ucode is required for dpm (dynamic power management), but if it's missing just skip dpm setup and don't disable acceleration. Should fix: https://bugs.freedesktop.org/show_bug.cgi?id=67876 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-07drm/radeon: always program the MC on startupAlex Deucher
For r6xx+ asics. This mirrors the behavior of pre-r6xx asics. We need to program the MC even if something else in startup() fails. Failure to do so results in an unusable GPU.

2013-06-03radeon: Fix system hang issue when using KMS with older cardsAdis Hamzić
The current radeon driver initialization routines, when using KMS, are written so that the IRQ installation routine is called before initializing the WB buffer and the CP rings. With some ASICs, though, the IRQ routine tries to access the GFX_INDEX ring causing a call to RREG32 with the value of -1 in radeon_fence_read. This, in turn causes the system to completely hang with some cards, requiring a hard reset. A call stack that can cause such a hang looks like this (using rv515 ASIC for the example here): * rv515_init (rv515.c) * radeon_irq_kms_init (radeon_irq_kms.c) * drm_irq_install (drm_irq.c) * radeon_driver_irq_preinstall_kms (radeon_irq_kms.c) * rs600_irq_process (rs600.c) * radeon_fence_process - due to SW interrupt (radeon_fence.c) * radeon_fence_read (radeon_fence.c) * hang due to RREG32(-1) The patch moves the IRQ installation to the card startup routine, after the ring has been initialized, but before the IRQ has been set. This fixes the issue, but requires a check to see if the IRQ is already installed, as is the case in the system resume codepath. I have tested the patch on three machines using the rv515, the rv770 and the evergreen ASIC. They worked without issues. This seems to be a known issue and has been reported on several bug tracking sites by various distributions (see links below). Most of reports recommend booting the system with KMS disabled and then enabling KMS by reloading the radeon module. For some reason, this was indeed a usable workaround, however, UMS is now deprecated and disabled by default.
