2013-06-25drm/radeon: add initial ucode loading for CIK (v5)Alex Deucher2-0/+181
Currently the driver required 6 sets of ucode: 1. pfp - pre-fetch parser, part of the GFX CP 2. me - micro engine, part of the GFX CP 3. ce - constant engine, part of the GFX CP 4. rlc - interrupt, etc. controller 5. mc - memory controller (discrete cards only) 6. mec - compute engines, part of Compute CP V2: add documentation V3: update MC ucode V4: rebase V5: update mc ucode Signed-off-by: Alex Deucher <[email protected]>

The vm callbacks are the same as the SI ones right now (same regs and bits).

2013-06-25drm/radeon: add a reset work handlerAlex Deucher2-0/+19
New asics support non-privileged IBs. This allows us to skip IB checking in the driver since the hardware will check the command buffers for us. When using non-privileged IBs, if the CP encounters an illegal register in the command stream, it will halt and generate an interrupt. The CP needs to be reset to continue. For now just do a full GPU reset when this happens. Signed-off-by: Alex Deucher <[email protected]>

2013-06-25drm: fix fb leak in setcrtcDaniel Vetter2-6/+20
Drivers are allowed (actually have to) disable unrelated crtcs in their ->set_config callback (when we steal all the connectors from that crtc). If they do that they'll clear crtc->fb to NULL. Which results in a refcount leak, since the drm core is keeping track of that reference. To fix this track the old fb of all crtcs and adjust references for all of them. Of course, since we only hold an additional reference for the fb for the current crtc we need to increase refcounts before we drop the old one. This approach has the benefit that it inches us a bit closer to an atomic modeset world, where we want to update the config of all crtcs in one step. This regression has been introduce in the framebuffer refcount conversion, specifically in commit b0d1232589df5575c5971224ac4cb30e7e525884 Author: Daniel Vetter <[email protected]> Date: Tue Dec 11 01:07:12 2012 +0100 drm: refcounting for crtc framebuffers Reported-by: Russell King <[email protected]> Cc: Russell King <[email protected]> Cc: [email protected] Signed-off-by: Daniel Vetter <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
2013-06-25drm: check that ->set_config properly updates the fbDaniel Vetter1-0/+3
Historically drm lacked fb refcounting, so the updating of crtc->fb was done by the lower levels at a point convenient to get their own refcounting (e.g. refcounts for the underlying gem bo, pinning refcounts) right. With the introduction of refcounted fbs the drm core handled the fb refcounts, but still relied on drivers to update the crtc->fb pointer (this approach required the least invasive changes in drivers). Enforce this contract with a WARN_ON. Signed-off-by: Daniel Vetter <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
2013-06-25drm/crtc-helper: explicit DPMS on after modesetDaniel Vetter1-6/+16
Atm the crtc helper implementation of set_config has really inconsisten semantics: If just an fb update is good enough, dpms state will be left as-is, but if we do a full modeset we force everything to dpms on. This change has already been applied to the i915 modeset code in commit e3de42b68478a8c95dd27520e9adead2af9477a5 Author: Imre Deak <[email protected]> Date: Fri May 3 19:44:07 2013 +0200 drm/i915: force full modeset if the connector is in DPMS OFF mode which according to Greg KH seems to aim for a new record in most Bugzilla: links in a commit message. The history of this dpms forcing is pretty interesting. This patch here is an almost-revert of commit 811aaa55ba21ab37407018cfc01770d6b037d3fb Author: Keith Packard <[email protected]> Date: Thu Feb 3 16:57:28 2011 -0800 drm: Only set DPMS ON when actually configuring a mode which fixed the bug of trying to dpms on disabled outputs, but introduced the new discrepancy between an fb update only and full modesets. The actual introduction of this goes back to commit bf9dc102e284a5aa78c73fc9d72e11d5ccd8669f Author: Keith Packard <[email protected]> Date: Fri Nov 26 10:45:58 2010 -0800 drm: Set connector DPMS status to ON in drm_crtc_helper_set_config And if you'd dig around in the i915 driver code there's even more fun around forcing dpms on and losing our heads and temper of the resulting inconsistencies. Especially the DP re-training code had tons of funny stuff in it. Signed-off-by: Daniel Vetter <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

2013-06-25drm/crtc-helpers: Enforce sane set_config apiDaniel Vetter1-7/+6
There's no point in trying to clean up after driver-bugs, so just blow up. Furthermore it's an interface abuse to set no mode but have an fb and aslo to try to set an fb without enough connectors. These two spefici cases of interface abuse have been committed by the fb helper, but that's been fixed meanwhile in commit 7e53f3a423146745a4e4bb93362d488dfad502a8 Author: Daniel Vetter <[email protected]> Date: Mon Jan 21 10:52:17 2013 +0100 drm/fb-helper: fixup set_config semantics The i915 driver has been shipping since a while with these BUGs with no reports, so should be save. Note that this drops an ugly case where we clear crtc->fb behind the upper levels back and so cause a refcounting mayhem, which Russell Kins spotted while trying to hunt down a drm framebuffer leak.

The following commit caused a fatal oops when booting on mpc83xx with a non-express PCI bus (regardless of whether a PCI device is present): commit 50d8f87d2b39313dae9d0a2d9b23d377328f2f7b Author: Rojhalat Ibrahim <[email protected]> Date: Mon Apr 8 10:15:28 2013 +0200 powerpc/fsl-pci Make PCIe hotplug work with Freescale PCIe controllers Up to now the PCIe link status on Freescale PCIe controllers was only checked once at boot time.
