2018-10-11drm/nouveau/disp: keep track of high-speed state, program into clockIlia Mirkin3-4/+14
The register programmed by the clock method needs to contain a different setting for the link speed as well as special divider settings. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2018-10-11drm/nouveau/disp: add a way to configure scrambling/tmds for hdmi 2.0Ilia Mirkin3-3/+13
High pixel clocks are required to use a 40 TMDS divider instead of 10, and even low ones may optionally use scrambling depending on device support. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-10-11drm/nouveau: Start using new drm_dev initialization helpersLyude Paul1-72/+101
Per the documentation in drm_get_pci_dev(), this function is deprecated and shouldn't be used anymore. As it turns out, we're going to need to stop using drm_get_pci_dev() anyway in order to allow us to turn off the card before full system shutdowns, otherwise we'll hit race conditions with userspace while trying to tear down the card on shutdown. So, start using drm_dev_get() and drm_dev_put(), and just turn our load/unload callbacks into open coded init/fini() functions.

2018-10-11drm/nouveau: Fix potential memory leak in nouveau_drm_load()Lyude Paul1-2/+4
We forget to free drm in all instances of failure, and additionally also forget to destroy the master client if the other client fails initialization. Signed-off-by: Lyude Paul <lyude@redhat.com> Cc: Karol Herbst <kherbst@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-10-11drm/nouveau: Refactor nvXX_backlight_init()Lyude Paul1-88/+72
There's literally no difference between any of the backlight init functions besides the backlight properties they set and the backlight callbacks that they set, so move all of the duplicated backlight init code out of there and into nouveau_backlight_init(). This gets rid of a lot of copy pasta! Changes since v1: - Some of the pre-refactor callbacks were storing nv_encoder in callback data for the backlight devices that they registered, as opposed to nouveau_drm. This got missed and caused some bugs that didn't originally appear on my setup (NULL kernel derefs) for some reason. So, fix this by finding the nouveau_encoder in nouveau_backlight_init(), and using that as the callback data for all gens instead even if they don't care about the encoder.

2018-10-11drm/nouveau: Move backlight device into nouveau_connectorLyude Paul6-100/+133

According to the documentation on the drm_connector->late_register() hook, the ->late_register() hook should be used for adding extra connector-related devices. Vice versa, the ->early_unregister() hook is meant to be used for removing those devices. So: gut nouveau_drm->bl_list and nouveau_drm->backlight, and replace them with per-connector backlight structures. Additionally, move backlight registration/teardown into the ->late_register() and ->early_unregister() hooks so that DRM can give us a chance to remove the backlight before the connector is even removed. This appears to fix the problem once and for all.

2018-10-11drm/nouveau: Fix nv50_mstc->best_encoder()Lyude Paul1-10/+4
As mentioned in the previous commit, we currently prevent new modesets on recently-removed MST connectors by returning no encoder from our ->best_encoder() callback once the MST port has disappeared. This is wrong however, because it prevents legacy modesetting users from being able to disable CRTCs on MST connectors after the connector's respective topology has disappeared. So, fix this by instead by just always returning a valid encoder.

2018-10-10drm/amdgpu: Suppress keypresses from ACPI_VIDEO eventsLyude Paul1-5/+12
Currently we return NOTIFY_DONE for any event which we don't think is ours. However, many laptops will send more then just an ATIF event and will also send an ACPI_VIDEO_NOTIFY_PROBE event as well. Since we don't check for this, we return NOTIFY_DONE which causes a keypress for the ACPI event to be propogated to userspace. This is the equivalent of someone pressing the display key on a laptop every time there's a hotplug event. So, check for ACPI_VIDEO_NOTIFY_PROBE events and suppress keypresses from them.

But it appears they actually came from my patch series: [ 2.980512] [drm:drm_atomic_helper_check_modeset [drm_kms_helper]] Updating routing for [CONNECTOR:65:eDP-1] [ 2.980516] [drm:drm_atomic_helper_check_modeset [drm_kms_helper]] [CONNECTOR:65:eDP-1] is not registered [ 2.980516] ------------[ cut here ]------------ [ 2.980519] Could not determine valid watermarks for inherited state [ 2.980553] WARNING: CPU: 3 PID: 551 at drivers/gpu/drm/i915/intel_display.c:14983 intel_modeset_init+0x14d7/0x19f0 [i915] [ 2.980556] Modules linked in: i915(O+) i2c_algo_bit drm_kms_helper(O) syscopyarea sysfillrect sysimgblt fb_sys_fops drm(O) intel_rapl x86_pkg_temp_thermal iTCO_wdt wmi_bmof coretemp crc32_pclmul psmouse i2c_i801 mei_me mei i2c_core lpc_ich mfd_core tpm_tis tpm_tis_core wmi tpm thinkpad_acpi pcc_cpufreq video ehci_pci crc32c_intel serio_raw ehci_hcd xhci_pci xhci_hcd [ 2.980577] CPU: 3 PID: 551 Comm: systemd-udevd Tainted: G O 4.19.0-rc7Lyude-Test+ #1 [ 2.980579] Hardware name: LENOVO 20BWS1KY00/20BWS1KY00, BIOS JBET63WW (1.27 ) 11/10/2016 [ 2.980605] RIP: 0010:intel_modeset_init+0x14d7/0x19f0 [i915] [ 2.980607] Code: 89 df e8 ec 27 02 00 e9 24 f2 ff ff be 03 00 00 00 48 89 df e8 da 27 02 00 e9 26 f2 ff ff 48 c7 c7 c8 d1 34 a0 e8 23 cf dc e0 <0f> 0b e9 7c fd ff ff f6 c4 04 0f 85 37 f7 ff ff 48 8b 83 60 08 00 [ 2.980611] RSP: 0018:ffffc90000287988 EFLAGS: 00010282 [ 2.980614] RAX: 0000000000000000 RBX: ffff88031b488000 RCX: 0000000000000006 [ 2.980617] RDX: 0000000000000007 RSI: 0000000000000086 RDI: ffff880321ad54d0 [ 2.980620] RBP: ffffc90000287a10 R08: 000000000000040a R09: 0000000000000065 [ 2.980623] R10: ffff88030ebb8f00 R11: ffffffff81416590 R12: ffff88031b488000 [ 2.980626] R13: ffff88031b4883a0 R14: ffffc900002879a8 R15: ffff880319099800 [ 2.980630] FS: 00007f475620d180(0000) GS:ffff880321ac0000(0000) knlGS:0000000000000000 [ 2.980633] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 2.980636] CR2: 00007f9ef28018a0 CR3: 000000031b72c001 CR4: 00000000003606e0 [ 2.980639] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 2.980642] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 2.980645] Call Trace: [ 2.980675] i915_driver_load+0xb0e/0xdc0 [i915] [ 2.980681] ? kernfs_add_one+0xe7/0x130 [ 2.980709] i915_pci_probe+0x46/0x60 [i915] [ 2.980715] pci_device_probe+0xd4/0x150 [ 2.980719] really_probe+0x243/0x3b0 [ 2.980722] driver_probe_device+0xba/0x100 [ 2.980726] __driver_attach+0xe4/0x110 [ 2.980729] ? driver_probe_device+0x100/0x100 [ 2.980733] bus_for_each_dev+0x74/0xb0 [ 2.980736] driver_attach+0x1e/0x20 [ 2.980739] bus_add_driver+0x159/0x230 [ 2.980743] ? 0xffffffffa0393000 [ 2.980746] driver_register+0x70/0xc0 [ 2.980749] ? 0xffffffffa0393000 [ 2.980753] __pci_register_driver+0x57/0x60 [ 2.980780] i915_init+0x55/0x58 [i915] [ 2.980785] do_one_initcall+0x4a/0x1c4 [ 2.980789] ? do_init_module+0x27/0x210 [ 2.980793] ? kmem_cache_alloc_trace+0x131/0x190 [ 2.980797] do_init_module+0x60/0x210 [ 2.980800] load_module+0x2063/0x22e0 [ 2.980804] ? vfs_read+0x116/0x140 [ 2.980807] ? vfs_read+0x116/0x140 [ 2.980811] __do_sys_finit_module+0xbd/0x120 [ 2.980814] ? __do_sys_finit_module+0xbd/0x120 [ 2.980818] __x64_sys_finit_module+0x1a/0x20 [ 2.980821] do_syscall_64+0x5a/0x110 [ 2.980824] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [ 2.980826] RIP: 0033:0x7f4754e32879 [ 2.980828] Code: 00 c3 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d f7 45 2c 00 f7 d8 64 89 01 48 [ 2.980831] RSP: 002b:00007fff43fd97d8 EFLAGS: 00000246 ORIG_RAX: 0000000000000139 [ 2.980834] RAX: ffffffffffffffda RBX: 0000559a44ca64f0 RCX: 00007f4754e32879 [ 2.980836] RDX: 0000000000000000 RSI: 00007f475599f4cd RDI: 0000000000000018 [ 2.980838] RBP: 00007f475599f4cd R08: 0000000000000000 R09: 0000000000000000 [ 2.980839] R10: 0000000000000018 R11: 0000000000000246 R12: 0000000000000000 [ 2.980841] R13: 0000559a44c92fd0 R14: 0000000000020000 R15: 0000000000000000 [ 2.980881] WARNING: CPU: 3 PID: 551 at drivers/gpu/drm/i915/intel_display.c:14983 intel_modeset_init+0x14d7/0x19f0 [i915] [ 2.980884] ---[ end trace 5eb47a76277d4731 ]--- The cause of this appears to be due to the fact that if there's pre-existing display state that was set by the BIOS when i915 loads, it will attempt to perform a modeset before the driver is registered with userspace. Since this happens before the driver's registered with userspace, it's connectors are also unregistered and thus-states which would turn on DPMS on a connector end up getting rejected since the connector isn't registered. These bugs managed to get past Intel's CI partially due to the fact it never ran a full test on my patches for some reason, but also because all of the tests unload the GPU once before running. Since this bug is only really triggered when the drivers tries to perform a modeset before it's been fully registered with userspace when coming from whatever display configuration the firmware left us with, it likely would never have been picked up by CI in the first place. After some discussion with vsyrjala, we decided the best course of action would be to just move the unregistered connector checks out of update_connector_routing() and into drm_atomic_set_crtc_for_connector(). The reason for this being that legacy modesetting isn't going to be expecting failures anywhere (at least this is the case with X), so ideally we want to ensure that any DPMS changes will still work even on unregistered connectors. Instead, we now only reject new modesets which would change the current CRTC assigned to an unregistered connector unless no new CRTC is being assigned to replace the connector's previous one.

2018-10-10drm/i915/dp: Link train Fallback on eDP only if fallback link BW can fit ↵Manasi Navare2-17/+39
panel's native mode This patch fixes the original commit c0cfb10d9e1de49 ("drm/i915/edp: Do not do link training fallback or prune modes on EDP") that causes a blank screen in case of certain eDP panels (Eg: seen on Dell XPS13 9350) where first link training fails and a retraining is required by falling back to lower link rate/lane count. In case of some panels they advertise higher link rate/lane count than whats required for supporting the panel's native mode. But we always link train at highest link rate/lane count for eDP and if that fails we can still fallback to lower link rate/lane count as long as the fallback link BW still fits the native mode to avoid pruning the panel's native mode yet retraining at fallback values to recover from a blank screen. v3: * Add const for fixed_mode (Ville) v2: * Send uevent if link failure on eDP unconditionally Fixes: c0cfb10d9e1d ("drm/i915/edp: Do not do link training fallback or prune modes on EDP") Cc: Clinton Taylor <clinton.a.taylor@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: <stable@vger.kernel.org> # v4.17+ Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107489 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=105338 Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Tested-by: Alexander Wilson <alexander.wilson@ncf.edu> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181009212804.702-1-manasi.d.navare@intel.com
