2020-09-01drm/nouveau/kms: Don't change EDID when it hasn't actually changedLyude Paul1-27/+27
Currently in nouveau_connector_ddc_detect() and nouveau_connector_detect_lvds(), we start the connector probing process by releasing the previous EDID and informing DRM of the change. However, since commit 5186421cbfe2 ("drm: Introduce epoch counter to drm_connector") drm_connector_update_edid_property() actually checks whether the new EDID we've specified is different from the previous one, and updates the connector's epoch accordingly if it is. But, because we always set the EDID to NULL first in nouveau_connector_ddc_detect() and nouveau_connector_detect_lvds() we end up making DRM think that the EDID changes every single time we do a connector probe - which isn't needed. So, let's fix this by not clearing the EDID at the start of the connector probing process, and instead simply changing or removing it once near the end of the probing process. This will help prevent us from sending unneeded hotplug events to userspace when nothing has actually changed.

2020-09-01drm/nouveau/kms/nv50-: Add support for DP_SINK_COUNTLyude Paul2-5/+50
This is another bit that we never implemented for nouveau: dongle detection. When a "dongle", e.g. an active display adaptor, is hooked up to the system and causes an HPD to be fired, we don't actually know whether or not there's anything plugged into the dongle without checking the sink count. As a result, plugging in a dongle without anything plugged into it currently results in a bogus EDID retrieval error in the kernel log. Additionally, most dongles won't send another long HPD signal if the user suddenly plugs something in, they'll only send a short HPD IRQ with the expectation that the source will check the sink count and reprobe the connector if it's changed - something we don't actually do. As a result, nothing will happen if the user plugs the dongle in before plugging something into the dongle. So, let's fix this by checking the sink count in both nouveau_dp_probe_dpcd() and nouveau_dp_irq(), and reprobing the connector if things change.

2020-09-01drm/nouveau/kms: Only use hpd_work for reprobing in HPD pathsLyude Paul7-36/+86
Currently we perform both short IRQ handling for DP, and connector reprobing in the HPD IRQ handler. However since we need to grab connection_mutex in order to reprobe a connector, in theory we could accidentally block ourselves from handling any short IRQs until after a modeset completes if a connector hotplug happens to occur in parallel with a modeset. I haven't seen this actually happen yet, but since we're cleaning up nouveau's hotplug handling code anyway and we already have a hpd worker, we can simply fix this by only relying on the HPD worker to actually reprobe connectors when we receive a HPD IRQ. We also add a mask to nouveau_drm to keep track of which connectors are waiting to be reprobed in response to an HPD IRQ.

2020-09-01drm/nouveau/kms/nv50-: Refactor and cleanup DP HPD handlingLyude Paul7-137/+244
First some backstory here: Currently, we keep track of whether or not we've enabled MST or not by trying to piggy-back off the MST helpers. This means that in order to check whether MST is enabled or not, we actually need to grab drm_dp_mst_topology_mgr.lock. Back when I originally wrote this, I did this piggy-backing with the intention that I'd eventually be teaching our MST helpers how to recover when an MST device has stopped responding, which in turn would require the MST helpers having a way of disabling MST independently of the driver. Note that this was before I reworked locking in the MST helpers, so at the time we were sticking random things under &mgr->lock - which grabbing this lock was meant to protect against. This never came to fruition because doing such a reset safely turned out to be a lot more painful and impossible then it sounds, and also just risks us working around issues with our MST handlers that should be properly fixed instead. Even if it did though, simply calling drm_dp_mst_topology_mgr_set_mst() from the MST helpers (with the exception of when we're tearing down our MST managers, that's always OK) wouldn't have been a bad idea, since drivers like nouveau and i915 need to do their own book keeping immediately after disabling MST. So-implementing that would likely require adding a hook for helper-triggered MST disables anyway. So, fast forward to now - we want to start adding support for all of the miscellaneous bits of the DP protocol (for both SST and MST) we're missing before moving on to supporting more complicated features like supporting different BPP values on MST, DSC, etc. Since many of these features only exist on SST and make use of DP HPD IRQs, we want to be able to atomically check whether we're servicing an MST IRQ or SST IRQ in nouveau_connector_hotplug(). Currently we literally don't do this at all, and just handle any kind of possible DP IRQ we could get including ESIs - even if MST isn't actually enabled. This would be very complicated and difficult to fix if we need to hold &mgr->lock while handling SST IRQs to ensure that the MST topology state doesn't change under us. What we really want here is to do our own tracking of whether MST is enabled or not, similar to drivers like i915, and define our own locking order to decomplicate things and avoid hitting locking issues in the future. So, let's do this by refactoring our MST probing/enabling code to use our own MST bookkeeping, along with adding a lock for protecting DP state that needs to be checked outside of our connector probing functions. While we're at it, we also remove a bunch of unneeded steps we perform when probing/enabling MST: * Enabling bits in MSTM_CTRL before calling drm_dp_mst_topology_mgr_set_mst(). I don't think these ever actually did anything, since the nvif methods for enabling MST don't actually do anything DPCD related and merely indicate to nvkm that we've turned on MST. * Checking the MSTM_CTRL bit is intact when checking the state of an enabled MST topology in nv50_mstm_detect(). I just added this to be safe originally, but now that we try reading the DPCD when probing DP connectors it shouldn't be needed as that will abort our hotplug probing if the device was removed well before we start checking for MST.. * All of the duplicate DPCD version checks. This leaves us with much nicer looking code, a much more sensible locking scheme, and an easy way of checking whether MST is enabled or not for handling DP HPD IRQs. v2: * Get rid of accidental newlines v4: * Fix uninitialized usage of mstm in nv50_mstm_detect() - thanks kernel bot!
