2019-12-17drm/i915: DSI: select correct PWM controller to use based on the VBTHans de Goede1-3/+13
At least Bay Trail (BYT) and Cherry Trail (CHT) devices can use 1 of 2 different PWM controllers for controlling the LCD's backlight brightness. Either the one integrated into the PMIC or the one integrated into the SoC (the 1st LPSS PWM controller). So far in the LPSS code on BYT we have skipped registering the LPSS PWM controller "pwm_backlight" lookup entry when a Crystal Cove PMIC is present, assuming that in this case the PMIC PWM controller will be used. On CHT we have been relying on only 1 of the 2 PWM controllers being enabled in the DSDT at the same time; and always registered the lookup. So far this has been working, but the correct way to determine which PWM controller needs to be used is by checking a bit in the VBT table and recently I've learned about 2 different BYT devices: Point of View MOBII TAB-P800W Acer Switch 10 SW5-012 Which use a Crystal Cove PMIC, yet the LCD is connected to the SoC/LPSS PWM controller (and the VBT correctly indicates this), so here our old heuristics fail. This commit fixes using the wrong PWM controller on these devices by calling pwm_get() for the right PWM controller based on the VBT dsi.config.pwm_blc bit. Note this is part of a series which contains 2 other patches which renames the PWM lookup for the 1st SoC/LPSS PWM from "pwm_backlight" to "pwm_pmic_backlight" and the PWM lookup for the Crystal Cove PMIC PWM from "pwm_backlight" to "pwm_pmic_backlight".

2019-12-16drm/i915/gem: Apply lmem size restriction to get_pagesChris Wilson3-4/+4
When creating a handle, it is just that, an abstract handle. The fact that we cannot currently support a handle larger than the size of the backing storage is an artifact of our whole-object-at-a-time handling in get_pages() and being an implementation limitation is best handled at that point -- similar to shmem, where we only barf when asked to populate the whole object if larger than RAM. (Pinning the whole object at a time is major hindrance that we are likely to have to overcome in the near future.) In the case of the buddy allocator, the late check is preferable as the request size may often be smaller than the required size.

2019-12-16drm/i915: opregion: set opregion chpd value to indicate the driver handles hotplugHans de Goede1-0/+7
According to both the old acpi_igd_opregion_spec_0.pdf and the newer skl_opregion_rev0p5.pdf opregion specification documents, if a driver handles hotplug events itself, it should set the opregion CHPD field to 1 to indicate this and the firmware should respond to this by no longer sending ACPI 0x00 notification events on e.g. lid-state changes. Specifically skl_opregion_rev0p5.pdf states thid in the documentation of the CHPD word: "Re-enumeration trigger logic in System BIOS MUST be disabled for all the Operating Systems supporting Hot-Plug (e.g., Windows* Longhorn and above)." Note the MUST in there. We ignore these notifications, so this should not be a problem but many recent DSTDs seem to all have the same copy-pasted bug in the GNOT() AML function which is used to send these notifications. Windows likely does not hit this bug as it presumably correcty sets CHPD to 1. Here is an example of the broken GNOT() method: Method (GNOT, 2, NotSerialized) { ... CEVT = Arg0 CSTS = 0x03 If (((CHPD == Zero) && (Arg1 == Zero))) { If (((OSYS > 0x07D0) || (OSYS < 0x07D6))) { Notify (PCI0, Arg1) } Else { Notify (GFX0, Arg1) } } ... Notice that the condition for the If is always true I believe that the || like needs to be an &&, but there is nothing we can do about this and in my own DSDT archive 55 of the 93 DSDTs have this issue. When the if is true the notification gets send to the PCI root instead of only to the GFX0 device. This causes Linux to re-enumerate PCI devices whenever the LID opens / closes, leading to unexpected messages in dmesg: Suspend through lid close: [ 313.598199] intel_atomisp2_pm 0000:00:03.0: Refused to change power state, currently in D3 [ 313.664453] intel_atomisp2_pm 0000:00:03.0: Refused to change power state, currently in D3 [ 313.737982] pci_bus 0000:01: Allocating resources [ 313.738036] pcieport 0000:00:1c.0: bridge window [io 0x1000-0x0fff] to [bus 01] add_size 1000 [ 313.738051] pcieport 0000:00:1c.0: bridge window [mem 0x00100000-0x000fffff 64bit pref] to [bus 01] add_size 200000 add_align 100000 [ 313.738111] pcieport 0000:00:1c.0: BAR 15: assigned [mem 0x91000000-0x911fffff 64bit pref] [ 313.738128] pcieport 0000:00:1c.0: BAR 13: assigned [io 0x1000-0x1fff] Resume: [ 813.623894] pci 0000:00:03.0: [8086:22b8] type 00 class 0x048000 [ 813.623955] pci 0000:00:03.0: reg 0x10: [mem 0x00000000-0x003fffff] [ 813.630477] pci 0000:00:03.0: BAR 0: assigned [mem 0x91c00000-0x91ffffff] [ 854.579101] intel_atomisp2_pm 0000:00:03.0: Refused to change power state, currently in D3 And more importantly this re-enumeration races with suspend/resume causing enumeration to not be complete when assert_isp_power_gated() from drivers/gpu/drm/i915/display/intel_display_power.c runs.

Sometimes we want to override a connector's panel_orientation from the kernel commandline. Either for testing and for special cases, e.g. a kiosk like setup which uses a TV mounted in portrait mode. Users can already specify a "rotate" option through a video= kernel cmdline option. But that only supports 0/180 degrees (see drm_client_modeset TODO) and only works for in kernel modeset clients, not for userspace kms users. The "panel-orientation" connector property OTOH does support 90/270 degrees as it leaves dealing with the rotation up to userspace and this does work for userspace kms clients (at least those which support this property).

Before this commit it was impossible to combine an extra mode argument specified directly after the resolution with an option, e.g. video=HDMI-1:720x480e,rotate=180 would not work, either the "e" to force enable would need to be dropped or the ",rotate=180", otherwise the mode_option would not be accepted. This commit fixes this by setting parse_extras to true in this case, so that drm_mode_parse_cmdline_res_mode() parses the extra arguments directly after the resolution.

Before this commit it was impossible to add an extra mode argument after a bpp or refresh specifier, combined with an option, e.g. video=HDMI-1:720x480-24e,rotate=180 would not work, either the "e" to force enable would need to be dropped or the ",rotate=180", otherwise the mode_option would not be accepted.

2019-12-16drm/modes: parse_cmdline: Fix possible reference past end of stringHans de Goede1-38/+30
Before this commit, if the last option of a video=... option is for example "rotate" without a "=<value>" after it then delim will point to the terminating 0 of the string, and value which is sets to <delim + 1> will point one position past the end of the string. This commit fixes this by enforcing that the contents of delim equals '=' as it should be for options which take a value, this check is done in a new drm_mode_parse_cmdline_int helper function which factors out the common integer parsing code for all the options which take an int.

While the common case is that the dsi controller uses an internal dphy, accessed through the phy registers inside the dsi controller, there is also the possibility to use a separate dphy from a different vendor. One such case is the Rockchip px30 that uses a Innosilicon Mipi dphy, so add the support for handling such a constellation, including the pll also getting generated inside that external phy. changes in v5: - rebased on top of 5.5-rc1 - merged with dsi timing change to prevent ordering conflicts Signed-off-by: Heiko Stuebner <heiko.stuebner@theobroma-systems.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191209143130.4553-5-heiko@sntech.de

If implementation-specific phy_ops need to be defined they probably should be enabled before trying to talk to the panel and disabled only after the panel was disabled. Right now they are enabled last and disabled first, so might make it impossible to talk to some panels - example for this being the px30 with an external Innosilicon dphy that needs the phy to be enabled to transfer commands to the panel.

The timing values for dw-dsi are often dependent on the used display and according to Philippe Cornu will most likely also depend on the used phy technology in the soc-specific implementation. To solve this and allow specific implementations to define them as needed add a new get_timing callback to phy_ops and call this from the dphy_timing function to retrieve the necessary values for the specific mode. Right now this handles the hs2lp + lp2hs where Rockchip SoCs need handling according to the phy speed, while STM seems to be ok with static values. changes in v5: - rebase on 5.5-rc1 - merge into px30 dsi series to prevent ordering conflicts changes in v4: - rebase to make it directly fit on top of drm-misc-next after all changes in v3: - check existence of phy_ops->get_timing in __dw_mipi_dsi_probe() - emit actual error when get_timing() call fails - add tags from Philippe and Yannick changes in v2: - add driver-specific handling, don't force all bridge users to use the same timings, as suggested by Philippe Suggested-by: Philippe Cornu <philippe.cornu@st.com> Signed-off-by: Heiko Stuebner <heiko.stuebner@theobroma-systems.com> Reviewed-by: Philippe Cornu <philippe.cornu@st.com> Tested-by: Yannick Fertre <yannick.fertre@st.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191209143130.4553-2-heiko@sntech.de

2019-12-16drm/i915/tgl: Drop Wa#1178Matt Roper2-6/+4
The TGL workaround database no longer shows Wa #1178 (or anything similar under different workaround names/numbers) so we should be able to drop it. In fact Swati just discovered that applying this workaround is the root cause of some power well enable failures we've been seeing in CI (gitlab issue 498). Once we stop applying this WA, TGL no longer utilizes any of the special handling provided by icl_combo_phy_aux_power_well_ops so we can just drop back to using the standard hsw-style power well ops instead. v3: Drop now-unused _TGL_AUX_ANAOVRD1_C definition too.

2019-12-16drm/i915: Copy across scheduler behaviour flags across submit fencesChris Wilson2-26/+89
We want the bonded request to have the same scheduler properties as its master so that it is placed at the same depth in the queue. For example, consider we have requests A, B and B', where B & B' are a bonded pair to run in parallel on two engines. A -> B \- B' B will run after A and so may be scheduled on an idle engine and wait on A using a semaphore. B' sees B being executed and so enters the queue on the same engine as A. As B' did not inherit the semaphore-chain from B, it may have higher precedence than A and so preempts execution. However, B' then sits on a semaphore waiting for B, who is waiting for A, who is blocked by B. Ergo B' needs to inherit the scheduler properties from B (i.e. the semaphore chain) so that it is scheduled with the same priority as B and will not be executed ahead of Bs dependencies. Furthermore, to prevent the priorities changing via the expose fence on B', we need to couple in the dependencies for PI. This requires us to relax our sanity-checks that dependencies are strictly in order. v2: Synchronise (B, B') execution on all platforms, regardless of using a scheduler, any no-op syncs should be elided.
