2017-07-07drm/radeon: Fix eDP for single-display iMac10,1 (v2)Mario Kleiner
The late 2009, 27 inch Apple iMac10,1 has an internal eDP display and an external Mini- Displayport output, driven by a DCE-3.2, RV730 Radeon Mobility HD-4670. The machine worked fine in a dual-display setup with eDP panel + externally connected HDMI or DVI-D digital display sink, connected via MiniDP to DVI or HDMI adapter. However, booting the machine single-display with only eDP panel results in a completely black display - even backlight powering off, as soon as the radeon modesetting driver loads. This patch fixes the single dispay eDP case by assigning encoders based on dig->linkb, similar to DCE-4+. While this should not be generally necessary (Alex: "...atom on normal boards should be able to handle any mapping."), Apple seems to use some special routing here. One remaining problem not solved by this patch is that an external Minidisplayport->DP sink does still not work on iMac10,1, whereas external DVI and HDMI sinks continue to work. The problem affects at least all tested kernels since Linux 3.13 - didn't test earlier kernels, so backporting to stable probably makes sense. v2: With the original patch from 2016, Alex was worried it will break other DCE3.2 systems. Use dmi_match() to apply this special encoder assignment only for the Apple iMac 10,1 from late 2009.

2016-03-09drm/radeon: Don't drop DP 2.7 Ghz link setup on some cards.Mario Kleiner
As observed on Apple iMac10,1, DCE-3.2, RV-730, link rate of 2.7 Ghz is not selected, because the args.v1.ucConfig flag setting for 2.7 Ghz gets overwritten by a following assignment of the transmitter to use. Move link rate setup a few lines down to fix this. In practice this didn't have any positive or negative effect on display setup on the tested iMac10,1 so i don't know if backporting to stable makes sense or not.

This enables the display scaler on all connectors for r5xx and newer asics. Previously we only enabled the scaler for fixed mode displays (eDP or LVDS) since they have to use the scaler to support non-native modes. Most other displays are multi-sync or have a built in scaler to support non-native modes. The default scaling mode for non-fixed displays is none which will use the scaler in the monitor. Note that we do not populate any fake modes like we do for fixed displays so it will only use the modes in the edid. For other modes, you'll need to populate them manually. bug: https://bugs.freedesktop.org/show_bug.cgi?id=80868 v2: properly handle scaling with no modes defined Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

git://people.freedesktop.org/~danvet/drm-intel into drm-next Bit a bit -fixes pull request in the merge window than usual dua to two feauture-y things: - Display CRCs are now enabled on all platforms, including the odd DP case on gm45/vlv. Since this is a testing-only feature it should ever hurt, but I figured it'll help with regression-testing -fixes. So I left it in and didn't postpone it to 3.14. - Display power well refactoring from Imre. Would have caused major pain conflict with the bdw stage 1 patches if I'd postpone this to -next. It's only an relatively small interface rework, so shouldn't cause pain. It's also been in my tree since almost 3 weeks already. That accounts for about two thirds of the pull, otherwise just bugfixes: - vlv backlight fix from Jesse/Jani - vlv vblank timestamp fix from Jesse - improved edp detection through vbt from Ville (fixes a vlv issue) - eDP vdd fix from Paulo - fixes for dvo lvds on i830M - a few smaller things all over Note: This contains a backmerge of v3.12. Since the -internal branch always applied on top of -nightly I need that unified base to merge bdw patches. So you'll get a conflict with radeon connector props when pulling this (and nouveau/master will also conflict a bit when Ben doesn't rebase). The backmerge itself only had conflicts in drm/i915.

2013-10-22drm/sysfs: sort out minor and connector device object lifetimes.Dave Airlie
So drm was abusing device lifetimes, by having embedded device structures in the minor and connector it meant that the lifetime of the internal drm objects (drm_minor and drm_connector) were tied to the lifetime of the device files in sysfs, so if something kept those files opened the current code would kfree the objects and things would go downhill from there. Now in reality there is no need for these lifetimes to be so intertwined, especailly with hotplugging of devices where we wish to remove the sysfs and userspace facing pieces before we can unwind the internal objects due to open userspace files or mmaps, so split the objects out so the struct device is no longer embedded and do what fbdev does and just allocate and remove the sysfs inodes separately.

2013-10-18drm/radeon: rework audio optionAlex Deucher
In 3.12 I changed audio to be enabled by default, but you still had to turn it on via xrandr. This was confusing to users so change it to minic the previous behavior: - audio option is set to -1 (auto) by default which is the current 3.12 behavior (audio is enabled but requires xrandr to turn it on). - if audio = 1, the audio is enabled without needing to mess with xrandr (previous behavior) - audio = 0 disables audio It retains the new feature of allowing the user to enable audio on the fly with xrandr, but turns audio on automatically if radeon.audio=1 is set which is what most users expect.

2013-09-11drm/radeon/atom: workaround vbios bug in transmitter table on rs880 (v2)Alex Deucher
The OUTPUT_ENABLE action jumps past the point in the coder where the data_offset is set on certain rs780 cards. This worked previously because the OUTPUT_ENABLE action is always called immediately after the ENABLE action so the data_offset remained set. In 6f8bbaf568c7f2c497558bfd04654c0b9841ad57 (drm/radeon/atom: initialize more atom interpretor elements to 0), we explictly reset data_offset to 0 between atom calls which then caused this to fail. The fix is to just skip calling the OUTPUT_ENABLE action on the problematic chipsets. The ENABLE action does the same thing and more. Ultimately, we could probably drop the OUTPUT_ENABLE action all together on DCE3 asics. fixes: https://bugzilla.kernel.org/show_bug.cgi?id=60791 v2: only rs880 seems to be affected Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
