2016-06-01drm: Wrap direct calls to driver->gem_free_object from CMAChris Wilson
Since the introduction of (struct_mutex) lockless GEM bo freeing, there are a pair of driver vfuncs for freeing the GEM bo, of which the driver may choose to only implement driver->gem_object_free_unlocked (and so avoid taking the struct_mutex along the free path). However, the CMA GEM helpers were still calling driver->gem_free_object directly, now NULL, and promptly dying on the fancy new lockless drivers. Oops. Robert Foss bisected this to b82caafcf2303 (drm/vc4: Use lockless gem BO free callback) on his vc4 device, but that just serves as an enabler for 9f0ba539d13ae (drm/gem: support BO freeing without dev->struct_mutex).

2016-06-01drm: fix fb refcount issue with atomic modesettingTomi Valkeinen
After commit 027b3f8ba9277410c3191d72d1ed2c6146d8a668 ("drm/modes: stop handling framebuffer special") extra fb refs are left around when doing atomic modesetting. The problem is that the new drm_property_change_valid_get() does not return anything in the '**ref' parameter, which causes drm_property_change_valid_put() to do nothing. For some reason this doesn't cause problems with legacy API. Also, previously the code only set the 'ref' variable for fbs, with this patch the 'ref' is set for all objects.

2016-06-01drm: make drm_atomic_set_mode_prop_for_crtc() more reliableTomi Valkeinen
drm_atomic_set_mode_prop_for_crtc() does not clear the state->mode, so old data may be left there when a new mode is set, possibly causing odd issues.

2016-06-01drm: add missing drm_mode_set_crtcinfo callTomi Valkeinen
When setting mode via MODE_ID property, drm_atomic_set_mode_prop_for_crtc() does not call drm_mode_set_crtcinfo() which possibly causes: "[drm:drm_calc_timestamping_constants [drm]] *ERROR* crtc 32: Can't calculate constants, dotclock = 0!" Whether the error is seen depends on the previous data in state->mode, as state->mode is not cleared when setting new mode. This patch adds drm_mode_set_crtcinfo() call to drm_mode_convert_umode(), which is called in both legacy and atomic paths. This should be fine as there's no reason to call drm_mode_convert_umode() without also setting the crtc related fields. drm_mode_set_crtcinfo() is removed from the legacy drm_mode_setcrtc() as that is no longer needed.

2016-05-31drm/i915: Update GEN6_PMINTRMSK setup with GuC enabledSagar Arun Kamble
On Loading, GuC sets PM interrupts routing (bit 31) and clears ARAT expired interrupt (bit 9). Host turbo also updates this register in RPS flows. This patch ensures bit 31 and bit 9 setup by GuC persists. ARAT timer interrupt is needed in GuC for various features. It also facilitates halting GuC and hence achieving RC6. PM interrupt routing will not impact RPS interrupt reception by host as GuC will redirect them. This patch fixes igt test pm_rc6_residency that was failing with guc load/submission enabled. Tested with SKL GuC v6.1 and BXT GuC v5.1 and v8.7. v2: i915_irq/i915_pm decoupling from intel_guc. (ChrisW) v3: restructuring the mask update and rebase w.r.t Ville's patch.

I added them as reserved 37 to reserved 40.

That is what all the get_*_optional() is about: we get optional GPIO handles, if they are not there, we get NULL. - Handle compatible ioctl() correctly: we need to convert the ioctl() pointer using compat_ptr() here like everyone else. - Disable the broken .to_irq() on the LPC32xx platform.

2016-05-31vga_switcheroo: Support deferred probing of audio clientsLukas Wunner
Daniel Vetter pointed out that vga_switcheroo_client_probe_defer() could be needed by audio clients as well. To avoid mistakes when someone adds conditions for these in the future, constrain the single existing condition to VGA clients by checking for PCI_BASE_CLASS_DISPLAY. This encompasses both PCI_CLASS_DISPLAY_VGA as well as PCI_CLASS_DISPLAY_3D, which is used by some Nvidia Optimus GPUs. Any future checks for audio clients should then be constrained to PCI_BASE_CLASS_MULTIMEDIA. v6: Spun out from commit introducing vga_switcheroo_client_probe_defer() to keep it a pure refactoring change.

2016-05-31vga_switcheroo: Add helper for deferred probingLukas Wunner
So far we've got one condition when DRM drivers need to defer probing on a dual GPU system and it's coded separately into each of the relevant drivers. As suggested by Daniel Vetter, deduplicate that code in the drivers and move it to a new vga_switcheroo helper. This yields better encapsulation of concepts and lets us add further checks in a central place. (The existing check pertains to pre-retina MacBook Pros and an additional check is expected to be needed for retinas.) One might be tempted to check deferred probing conditions in vga_switcheroo_register_client(), but this is usually called fairly late during driver load. The GPU is fully brought up and ready for switching at that point. On boot the ->probe hook is potentially called dozens of times until it finally succeeds, and each time we'd repeat bringup and teardown of the GPU, lengthening boot time considerably and cluttering logfiles. A separate helper is therefore needed which can be called right at the beginning of the ->probe hook. Note that amdgpu currently does not call this helper as the AMD GPUs built into MacBook Pros are only supported by radeon so far. v2: This helper could eventually be used by audio clients as well, so rephrase kerneldoc to refer to "client" instead of "GPU" and move the single existing check in an if block specific to PCI_CLASS_DISPLAY_VGA devices. Move documentation on that check from kerneldoc to a comment. (Daniel Vetter) v3: Mandate in kerneldoc that registration of client shall only happen after calling this helper. (Daniel Vetter) v4: Rebase on 412c8f7de011 ("drm/radeon: Return -EPROBE_DEFER when amdkfd not loaded") v5: Some Optimus GPUs use PCI_CLASS_DISPLAY_3D, make sure those are matched as well. (Emil Velikov) v6: The if-condition referring to PCI_BASE_CLASS_DISPLAY may be considered a functional change. Move to a separate commit to keep this a pure refactoring change.

A lot of the display drivers for OMAP use the gpio descriptor functions that are only available in linux/gpio.h if GPIOLIB is enabled and otherwise produce a build error: drivers/gpu/drm/omapdrm/displays/encoder-opa362.c: In function 'opa362_enable': drivers/gpu/drm/omapdrm/displays/encoder-opa362.c:101:3: error: implicit declaration of function 'gpiod_set_value_cansleep' [-Werror=implicit-function-declaration] drivers/gpu/drm/omapdrm/displays/panel-dpi.c: In function 'panel_dpi_probe_pdata': drivers/gpu/drm/omapdrm/displays/panel-dpi.c:189:23: error: implicit declaration of function 'gpio_to_desc' [-Werror=implicit-function-declaration] drivers/gpu/drm/omapdrm/displays/panel-sharp-ls037v7dw01.c: In function 'sharp_ls_enable': drivers/gpu/drm/omapdrm/displays/panel-sharp-ls037v7dw01.c:120:3: error: implicit declaration of function 'gpiod_set_value_cansleep' [-Werror=implicit-function-declaration] This replaces the existing linux/gpio.h with linux/gpio/consumer.h where needed. In case of panel-lgphilips-lb035q02.c however, we also have to include linux/gpio.h to get the definition of gpio_is_valid and gpio_set_value_cansleep that are used for the non-DT case.
