2020-01-03drm/i915/dsi: Control panel and backlight enable GPIOs on BYTHans de Goede2-1/+66
On Bay Trail devices the MIPI power on/off sequences for DSI LCD panels do not control the LCD panel- and backlight-enable GPIOs. So far, when the VBT indicates we should use the SoC for backlight control, we have been relying on these GPIOs being configured as output and driven high by the Video BIOS (GOP) when it initializes the panel. This does not work when the device is booted with a HDMI monitor connected as then the GOP will initialize the HDMI instead of the panel, leaving the panel black, even though the i915 driver tries to output an image to it. Likewise on some device-models when the GOP does not initialize the DSI panel it also leaves the mux of the PWM0 pin in generic GPIO mode instead of muxing it to the PWM controller. This commit makes the DSI code control the SoC GPIOs for panel- and backlight-enable on BYT, when the VBT indicates the SoC should be used for backlight control. It also ensures that the PWM0 pin is muxed to the PWM controller in this case. This fixes the LCD panel not lighting up on various devices when booted with a HDMI monitor connected. This has been tested to fix this on the following devices: Peaq C1010 Point of View MOBII TAB-P800W Point of View MOBII TAB-P1005W Terra Pad 1061 Yours Y8W81 Reviewed-by: Linus Walleij <[email protected]> Reviewed-by: Ville Syrjälä <[email protected]> Signed-off-by: Hans de Goede <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

driver Move the Crystal Cove PMIC panel GPIO lookup-table from drivers/mfd/intel_soc_pmic_core.c to the i915 driver. The moved looked-up table is adding a GPIO lookup to the i915 PCI device and the GPIO subsys allows only one lookup table per device, The intel_soc_pmic_core.c code only adds lookup-table entries for the PMIC panel GPIO (as it deals only with the PMIC), but we also need to be able to access some GPIOs on the SoC itself, which requires entries for these GPIOs in the lookup-table. Since the lookup-table is attached to the i915 PCI device it really should be part of the i915 driver, this will also allow us to extend it with GPIOs from other sources when necessary.

2020-01-03drm/i915/dsi: Init panel-enable GPIO to low when the LCD is initially off (v2)Hans de Goede3-6/+7
When the LCD has not been turned on by the firmware/GOP, because e.g. the device was booted with an external monitor connected over HDMI, we should not turn on the panel-enable GPIO when we request it. Turning on the panel-enable GPIO when we request it, means we turn it on too early in the init-sequence, which causes some panels to not correctly light up. This commits adds a panel_is_on parameter to intel_dsi_vbt_gpio_init() and makes intel_dsi_vbt_gpio_init() set the initial GPIO value accordingly. This fixes the panel not lighting up on a Thundersoft TST168 tablet when booted with an external monitor connected over HDMI.

2020-01-03drm/i915/dsi: Move poking of panel-enable GPIO to intel_dsi_vbt.cHans de Goede3-27/+48
On some older devices (BYT, CHT) which may use v2 VBT MIPI-sequences, we need to manually control the panel enable GPIO as v2 sequences do not do this. So far we have been carrying the code to do this on BYT/CHT devices with a Crystal Cove PMIC in vlv_dsi.c, but as this really is a shortcoming of the VBT MIPI-sequences, intel_dsi_vbt.c is a better place for this, so move it there. This is a preparation patch for adding panel-enable and backlight-enable GPIO support for BYT devices where instead of the PMIC the SoC is used for backlight control.

2020-01-02drm/i915/gem: Single page objects are naturally contiguousChris Wilson1-0/+3
Small objects that only occupy a single page are naturally contiguous, so mark them as such and allow them the special abilities that come with it. A more thorough treatment would extend i915_gem_object_pin_map() to support discontiguous lmem objects, following the example of ioremap_prot() and use get_vm_area() + remap_io_sg().

2020-01-02drm/mipi_dbi: Fix off-by-one bugs in mipi_dbi_blank()Geert Uytterhoeven1-2/+2
When configuring the frame memory window, the last column and row numbers are written to the column resp. page address registers. These numbers are thus one less than the actual window width resp. height. While this is handled correctly in mipi_dbi_fb_dirty() since commit 03ceb1c8dfd1e293 ("drm/tinydrm: Fix setting of the column/page end addresses."), it is not in mipi_dbi_blank(). The latter still forgets to subtract one when calculating the most significant bytes of the column and row numbers, thus programming wrong values when the display width or height is a multiple of 256.

2020-01-02drm/i915: reimplement header test featureMasahiro Yamada7-36/+31
I implemented a small build rule in drivers/gpu/drm/i915/Makefile without relying on the special header-test-y syntax that was removed in commit fcbb8461fd23 ("kbuild: remove header compile test"). I excluded some headers from the test coverage. I hope somebody intrested can take a closer look at them. Dummy subdir Makefiles can be removed altogether as single target build use case is now covered by commit 394053f4a4b3 ("kbuild: make single targets work more correctly"). v2 by Jani: - add selftests/i915_perf_selftests.h to no-header-test - add .gitignore for *.hdrtest Cc: Chris Wilson <[email protected]> Cc: Masahiro Yamada <[email protected]> Signed-off-by: Masahiro Yamada <[email protected]> Reviewed-by: Chris Wilson <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2020-01-01drm/i915/gem: Drop local vma->vm_file referenceChris Wilson2-0/+69
We use the global device inode, shared amongst all files, and not the user's device filp to provide the backing storage for the mmap. The vma->vm_file provides a redundant reference that breaks existing expected behaviour that closing the user's device fd will release the resources bound to it, if a mmap persists. (Even without the vma->vm_file, the mmap will persist past the user's fd as the storage is bound to the device, i.e. our reference is on the object not file.)

2020-01-01drm/i915/gt: Restore coarse power gatingChris Wilson1-2/+4
The coarse power gating was disabled as part of commit 2248a28384fe ("drm/i915/gen8+: Add RC6 CTX corruption WA") as a prelude to recover from the context corruption; the power gating itself has no direct impact on the RC6 context corruption. However, that recovery scheme was never implemented due to difficult corner cases, and so we no longer need to keep the power gating disabled.
