| * drm/amdgpu/dce: Don't turn off DP sink when disconnectedMichel Dänzer2018-03-221-19/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 7d617264eb22b18d979eac6e85877a141253034e upstream. Turning off the sink in this case causes various issues, because userspace expects it to stay on until it turns it off explicitly. Instead, turn the sink off and back on when a display is connected again. This dance seems necessary for link training to work correctly.

| * drm/amdgpu: Fix deadlock on runtime suspendLukas Wunner2018-03-181-20/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit aa0aad57909eb321746325951d66af88a83bc956 upstream. amdgpu's ->runtime_suspend hook calls drm_kms_helper_poll_disable(), which waits for the output poll worker to finish if it's running. The output poll worker meanwhile calls pm_runtime_get_sync() in amdgpu's ->detect hooks, which waits for the ongoing suspend to finish, causing a deadlock. Fix by not acquiring a runtime PM ref if the ->detect hooks are called in the output poll worker's context. This is safe because the poll worker is only enabled while runtime active and we know that ->runtime_suspend waits for it to finish.

* | micro-optimization: Use DSTRLEN to remove incorrect strlen usesJoe Maples2017-12-051-6/+6
|/ | | | | | | | | | | strlen is often used incorectly to get the length of strings defined at compile time. In these cases, the behavior can be replicated with sizeof(X) - 1, which is calculated at compile time rather than runtime, reducing overhead. I've created a simple macro to replace these instances and applied it to all the files compiled into the wahoo kernel. Signed-off-by: Joe Maples <joe@frap129.org>
* drm/radeon: fix atombios on big endianRoman Kapl2017-12-051-20/+18
| | | | | | | | | | | | | | | | | | | | | commit 4f626a4ac8f57ddabf06d03870adab91e463217f upstream. The function for byteswapping the data send to/from atombios was buggy for num_bytes not divisible by four. The function must be aware of the fact that after byte-swapping the u32 units, valid bytes might end up after the num_bytes boundary. This patch was tested on kernel 3.12 and allowed us to sucesfully use DisplayPort on and Radeon SI card. Namely it fixed the link training and EDID readout. The function is patched both in radeon and amd drivers, since the functions and the fixes are identical.

At dot clocks > approx. 250 Mhz, some of these calcs will overflow and cause miscalculation of latency watermarks, and for some overflows also divide-by-zero driver crash ("divide error: 0000 [#1] PREEMPT SMP" in "dce_v10_0_latency_watermark+0x12d/0x190").

* drm/amdgpu: Attach exclusive fence to prime exported bo's. (v5)Mario Kleiner2016-11-263-2/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 8e94a46c1770884166b31adc99eba7da65a446a7 upstream. External clients which import our bo's wait only for exclusive dmabuf-fences, not on shared ones, ditto for bo's which we import from external providers and write to. Therefore attach exclusive fences on prime shared buffers if our exported buffer gets imported by an external client, or if we import a buffer from an external exporter. See discussion in thread: https://lists.freedesktop.org/archives/dri-devel/2016-October/122370.html Prime export tested on Intel iGPU + AMD Tonga dGPU as DRI3/Present Prime render offload, and with the Tonga standalone as primary gpu. v2: Add a wait for all shared fences before prime export, as suggested by Christian Koenig. v3: - Mark buffer prime_exported in amdgpu_gem_prime_pin, so we only use the exclusive fence when exporting a bo to external clients like a separate iGPU, but not when exporting/importing from/to ourselves as part of regular DRI3 fd passing. - Propagate failure of reservation_object_wait_rcu back to caller. v4: - Switch to a prime_shared_count counter instead of a flag, which gets in/decremented on prime_pin/unpin, so we can switch back to shared fences if all clients detach from our exported bo. - Also switch to exclusive fence for prime imported bo's. v5: - Drop lret, instead use int ret -> long ret, as proposed by Christian.

* drm/amdgpu: Disable RPM helpers while reprobing connectors on resumeLyude2016-08-201-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 23a1a9e54e71593fe5657e883662995d181d2d6b upstream. Just about all of amdgpu's connector probing functions try to acquire runtime PM refs. If we try to do this in the context of amdgpu_resume_kms by calling drm_helper_hpd_irq_event(), we end up deadlocking the system. Since we're guaranteed to be holding the spinlock for RPM in amdgpu_resume_kms, and we already know the GPU is in working order, we need to prevent the RPM helpers from trying to run during the initial connector reprobe on resume. There's a couple of solutions I've explored for fixing this, but this one by far seems to be the simplest and most reliable (plus I'm pretty sure that's what disable_depth is there for anyway). Reproduction recipe: - Get any laptop dual GPUs using PRIME - Make sure runtime PM is enabled for amdgpu - Boot the machine - If the machine managed to boot without hanging, switch out of X to another VT. This should definitely cause X to hang infinitely. Changes since v1: - add appropriate #ifdef checks for CONFIG_PM. This is not very useful, but it appears some kernel test suites test compiling amdgpu with CONFIG_PM disabled, which results in this patch breaking the builds if we don't include this #ifdef Cc: Alex Deucher <alexdeucher@gmail.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Lyude <cpaul@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
