* | | | | drm/dp: Use large transactions for I2C over AUXSimon Farnsworth2015-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Older DisplayPort to DVI-D Dual Link adapters designed by Bizlink have bugs in their I2C over AUX implementation (fixed in newer revisions). They work fine with Windows, but fail with Linux. It turns out that they cannot keep an I2C transaction open unless the previous read was 16 bytes; shorter reads can only be followed by a zero byte transfer ending the I2C transaction. Copy Windows's behaviour, and read 16 bytes at a time. If we get a short reply, assume that there's a hardware bottleneck, and shrink our read size to match. For this purpose, use the algorithm in the DisplayPort 1.2 spec, in the hopes that it'll be closest to what Windows does. Also provide an unsafe module parameter for testing smaller transfer sizes, in case there are sinks out there that cannot work with Windows. Note also that despite the previous comment in drm_dp_i2c_xfer, this speeds up native DP EDID reads; Ville Syrjälä <ville.syrjala@linux.intel.com> found the following changes in his testing: Device under test: old -> with this patch DP->DVI (OUI 001cf8): 40ms -> 35ms DP->VGA (OUI 0022b9): 45ms -> 38ms Zotac DP->2xHDMI: 25ms -> 4ms Asus PB278 monitor: 22ms -> 3ms A back of the envelope calculation shows that peak theoretical transfer rate for 1 byte reads is around 60 kbit/s; with 16 byte reads, this increases to around 500 kbit/s, which explains the increase in speed.

Since we still force-disable planes it's only possible to hit this when racing multiple rmfb with fbdev restoring or similar evil things. As long as userspace is nice it's impossible to hit the BUG_ON. But the BUG_ON would most likely be hit from fbdev code, which usually invovles the console_lock besides all modeset locks. So very likely we'd never get the bug reports if this was hit in the wild, hence better be safe than sorry and backport. Spotted by Matt Roper while reviewing other patches.

This is clearly bogus, since ACPI mandates that devices are put into D3 by the OSPM if they are not wake-up sources. In the future we want to unify more of the driver's runtime and system suspend paths, for example by skipping all the system suspend/hibernation hooks if the device is runtime suspended already. Accordingly for all other platforms the goal is still to properly power down the device during hibernation. v2: - Another GEN4 Lenovo laptop had the same issue, while platforms from other vendors (including mobile and desktop, GEN4 and non-GEN4) seem to work fine. Based on this apply the workaround on all GEN4 Lenovo platforms. - add code comment about failing platforms (Ville) Reference: http://lists.freedesktop.org/archives/intel-gfx/2015-February/060633.html Reported-and-bisected-by: Bjørn Mork <bjorn@mork.no> Cc: stable@vger.kernel.org # v3.19 Signed-off-by: Imre Deak <imre.deak@intel.com> Acked-by: Daniel Vetter <daniel.vetter@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com>

(This is especially likely on hardware like 965gm where display fifo underruns are continuous and the GMCH cannot filter that interrupt souce.) As we enable our IRQ early so that we can use it during hardware probing, our interrupt handler must be prepared to handle a few sources prior to being fully configured. As such, we need to add a simple is-ready check prior to dereferencing our KMS state for reporting underruns.

The bug at hand is an underrun of the framebuffer reference with subsequent hilarity caused by the load detect code. Which is peculiar since the the exact same code works fine as the implementation of the legacy setcrtc ioctl. Let's look at the ingredients: - Currently our code is a crazy mix of legacy modeset interfaces to set the parameters and half-baked atomic state tracking underneath. While this transition is going we're using the transitional plane helpers to update the atomic side (drm_plane_helper_disable/update and friends), i.e. plane->state->fb. Since the state structure owns the fb those functions take care of that themselves. The legacy state (specifically crtc->primary->fb) is still managed by the old code (and mostly by the drm core), with the fb reference counting done by callers (core drm for the ioctl or the i915 load detect code). The relevant commit is commit ea2c67bb4affa84080c616920f3899f123786e56 Author: Matt Roper <matthew.d.roper@intel.com> Date: Tue Dec 23 10:41:52 2014 -0800 drm/i915: Move to atomic plane helpers (v9) - drm_plane_helper_disable has special code to handle multiple calls in a row - it checks plane->crtc == NULL and bails out. This is to match the proper atomic implementation which needs the crtc to get at the implied locking context atomic updates always need. See commit acf24a395c5a9290189b080383564437101d411c Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Jul 29 15:33:05 2014 +0200 drm/plane-helper: transitional atomic plane helpers - The universal plane code split out the implicit primary plane from the CRTC into it's own full-blown drm_plane object. As part of that the setcrtc ioctl (which updated both the crtc mode and primary plane) learned to set crtc->primary->crtc on modeset to make sure the plane->crtc assignments statate up to date in commit e13161af80c185ecd8dc4641d0f5df58f9e3e0af Author: Matt Roper <matthew.d.roper@intel.com> Date: Tue Apr 1 15:22:38 2014 -0700 drm: Add drm_crtc_init_with_planes() (v2) Unfortunately we've forgotten to update the load detect code. Which wasn't a problem since the load detect modeset is temporary and always undone before we drop the locks. - Finally there is a organically grown history (i.e. don't ask) around who sets the legacy plane->fb for the various driver entry points. Originally updating that was the drivers duty, but for almost all places we've moved that (plus updating the refcounts) into the core. Again the exception is the load detect code. Taking all together the following happens: - The load detect code doesn't set crtc->primary->crtc. This is only really an issue on crtcs never before used or when userspace explicitly disabled the primary plane. - The plane helper glue code short-circuits because of that and leaves a non-NULL fb behind in plane->state->fb and plane->fb. The state fb isn't a real problem (it's properly refcounted on its own), it's just the canary. - Load detect code drops the reference for that fb, but doesn't set plane->fb = NULL. This is ok since it's still living in that old world where drivers had to clear the pointer but the core/callers handled the refcounting. - On the next modeset the drm core notices plane->fb and takes care of refcounting it properly by doing another unref. This drops the refcount to zero, leaving state->plane now pointing at freed memory. - intel_plane_duplicate_state still assume it owns a reference to that very state->fb and bad things start to happen. Fix this all by applying the same duct-tape as for the legacy setcrtc ioctl code and set crtc->primary->crtc properly.

This can happen when we try to move a cursor but the CRTC's CTL (CONTROL) has not been allocated yet (inactive CRTC). It can also happens when we .atomic_check()/.atomic_flush() on a disabled CRTC. A CTL needs to be kept as long as the CRTC is alive. Releasing it after the last VBlank is safer than in .atomic_flush().
