| | * drm/radeon/kms: Add initial support for async DMA on cayman/TNAlex Deucher2012-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | There are 2 async DMA engines on cayman, one at 0xd000 and one at 0xd800. The programming interface is the same as evergreen however there are some changes to the commands for using vmids. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

| * | drm/ttm: remove no_wait_reserve, v3Maarten Lankhorst2012-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All items on the lru list are always reservable, so this is a stupid thing to keep. Not only that, it is used in a way which would guarantee deadlocks if it were ever to be set to block on reserve. This is a lot of churn, but mostly because of the removal of the argument which can be nested arbitrarily deeply in many places. No change of code in this patch except removal of the no_wait_reserve argument, the previous patch removed the use of no_wait_reserve. v2: - Warn if -EBUSY is returned on reservation, all objects on the list should be reservable. Adjusted patch slightly due to conflicts. v3: - Focus on no_wait_reserve removal only.

| * | drm/radeon: allow move_notify to be called without reservationMaarten Lankhorst2012-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The few places that care should have those checks instead. This allows destruction of bo backed memory without a reservation. It's required for being able to rework the delayed destroy path, as it is no longer guaranteed to hold a reservation before unlocking. However any previous wait is still guaranteed to complete, and it's one of the last things to be done before the buffer object is freed.

I've check the dp specs, and above 0xf there's a big gap and nothing that looks like we should cache it while a given device is plugged in. It's also the same value that i915.ko uses. Hence extend the various dpcd arrays in the radeon driver, use proper symbolic constants where applicable (one place overallocated the dpcd array to 25 bytes). Then also drop the rd_interval cache - radeon_dp_link_train_init re-reads the dpcd block, so the values we'll consume in train_cr and train_ce will always be fresh. To avoid needless diff-churn, #define the old size of dpcd as the new one and keep it around. v2: Alex Deucher noticed one place where I've forgotten to replace 8 with DP_RECEIVER_CAP_SIZE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On all dual CRTC GPUs the CRTC_CRT_ON in the RADEON_CRTC_EXT_CNTL register controls the CRTC of the primary DAC. Therefore it is set in the DAC DMPS function. This is different for GPU's with a single CRTC but a primary and a TV DAC: here it controls the single CRTC no matter where it is routed. Therefore we set it here. This avoids an elaborate on/off state tracking since both primary_dac_dpms() and tv_dac_dpms() functions would have to touch this bit. On single CRTC GPUs with just one DAC it's irrelevant where this bit is handled. agd5f: fix warning Signed-off-by: Egbert Eich <eich@suse.de> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

* | | DRM/Radeon: On DVI-I use Load Detection when EDID is bogus.Egbert Eich2012-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Radeon driver uses the analog/digital flag to determine if the DAC or the TMDS encoder should be enabled on a DVI-I connector. If the EDID is bogus this flag is no longer reliable. This fix adds a fallback to DAC load detection to determine if anything is connected to the DAC. If not and a (bogus) EDID is found it assumes a digital display is connected. This works around problems with some crappy IPMI devices using Radeon ES1000.

* | | DRM/Radeon: Fix primary DAC Load Detection for RV100 chips.Egbert Eich2012-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For Radeon 7500 ATI recommends a DAC_FORCE value of 0x1ac. This value works better on ES1000 (RV100) chips, too, as it doesn't produce any false positives on any cards I have tested. Therefore let's assume that this value is good for all RV100 and RV200 chipset generations. Signed-off-by: Egbert Eich <eich@suse.de> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
