* drm/radeon/kms: fix rs600 tlb flushJerome Glisse2010-04-26
| | | | | | | | | | | | | commit 30f69f3fb20bd719b5e1bf879339914063d38f47 upstream. Typo in in flush leaded to no flush of the RS600 tlb which ultimately leaded to massive system ram corruption, with this patch everythings seems to work properly.

* drm/radeon/kms: fix tv dac conflict resolverAlex Deucher2010-04-26
| | | | | | | | | | | | | | | | | commit 08d075116db3592db218bfe0f554cd93c9e12505 upstream. On systems with the tv dac shared between DVI and TV, we can only use the dac for one of the connectors. However, when using a digital monitor on the DVI port, you can use the dac for the TV connector just fine. Check the use_digital status when resolving the conflict.

* drm/radeon/kms: fix indirect buffer management V2Jerome Glisse2010-02-18
| | | | | | | | | | | | | | | | | | | | | | | | There is 3 different distinct states for an indirect buffer (IB) : 1- free with no fence 2- free with a fence 3- non free (fence doesn't matter) Previous code mixed case 2 & 3 in a single one leading to possible catastrophique failure. This patch rework the handling and properly separate each case. So when you get ib we set the ib as non free and fence status doesn't matter. Fence become active (ie has a meaning for the ib code) once the ib is scheduled or free. This patch also get rid of the alloc bitmap as it was overkill, we know go through IB pool list like in a ring buffer as the oldest IB is the first one the will be free. Fix : https://bugs.freedesktop.org/show_bug.cgi?id=26438 and likely other bugs.

For instance if ib allocation failed we did just warn about but then latter tried to access NULL ib ptr causing oops. This patch also protect r600_copy_blit with a mutex as otherwise one process might overwrite blit temporary data with new one possibly leading to GPU lockup. Should partialy or totaly fix: https://bugzilla.redhat.com/show_bug.cgi?id=553279 V2 failing blit initialization is not fatal, fallback to memcpy when this happen V3 init blit before startup as we pin in startup, remove duplicate code (this one was actualy tested unlike V2) Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

Second call drm_agp_info to fill in the info data struct, including aper_size. Finally do the check to see if the aper_size makes sense.

| * drm/kms/radeon: pick digitial encoders smarter. (v3)Dave Airlie2010-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | booting a Lenovo W500 with LVDS + DP outputs showed up a TODO we had on our list, to pick a correct digital encoder block. The LVTMA encoder requires the second digital encoder, all others can use any encoder at all. This fixes the digital encoder selection logic to enable LVDS/DP combos to work okay. V2: fix silly addition of connector dig_block and cleanup the other places in the code that pick the encoder. V3: rename to dig_encoder and clean up further - also fix the picking algorithm. tested on Lenovo W500 + desktop 3650 cards. Signed-off-by: Dave Airlie <airlied@redhat.com>
| * drm/radeon/kms: use active device to pick connector for encoderDave Airlie2010-01-31
| | | | | | | | | | | | | | | | | | | | | | On the W500 we have UNIPHY routed to both DVI and DP, this seems to always pick the DVI connector which means link training fails. Switch to using active device to pick the connector, this seems like it should be safe from a code review, and it fixes things a bit more here. Signed-off-by: Dave Airlie <airlied@redhat.com>
