2012-11-01drm/radeon: add load detection support for ext DAC on R200 (v2)Alex Deucher
The R200 asics use an external DAC for the secondary DAC. The current KMS code tries to use code for the integrated TV DAC for R200 which leads to unpredictable results since R200 does not have an integrated TV DAC. This patch ports the external DAC load detection support from the UMS driver to KMS. v2: fix typo in loop break logic Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Egbert Eich <eich@suse.de>
2012-11-01DRM/radeon: For single CRTC GPUs move handling of CRTC_CRT_ON to crtc_dpms().Egbert Eich
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>

2012-11-01DRM/Radeon: On DVI-I use Load Detection when EDID is bogus.Egbert Eich
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.

Allocations of page tables are made from the SA on demand, that should still work fine since all page tables are of the same size.

Pull workqueue changes from Tejun Heo: "This is workqueue updates for v3.7-rc1. A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts.
