etnaviv: fix gem object list corruption

2017-10-05T07:44:03Z

commit 518417525f3652c12fb5fad6da4ade66c0072fa3 upstream. All manipulations of the gem_object list need to be protected by the list mutex, as GEM objects can be created and freed in parallel. This fixes a kernel memory corruption. Signed-off-by: Lucas Stach Signed-off-by: Greg Kroah-Hartman

drm/sun4i: Implement drm_driver lastclose to restore fbdev console

2017-09-27T12:39:18Z

commit 2a596fc9d974bb040eda9ab70bf8756fcaaa6afe upstream. The drm_driver lastclose callback is called when the last userspace DRM client has closed. Call drm_fbdev_cma_restore_mode to restore the fbdev console otherwise the fbdev console will stop working.

drm/bridge: adv7511: Switch to using drm_kms_helper_hotplug_event()

2017-09-09T15:39:42Z

commit 6d5104c5a6b56385426e15047050584794bb6254 upstream. In chasing down a previous issue with EDID probing from calling drm_helper_hpd_irq_event() from irq context, Laurent noticed that the DRM documentation suggests that drm_kms_helper_hotplug_event() should be used instead. Thus this patch replaces drm_helper_hpd_irq_event() with drm_kms_helper_hotplug_event(), which requires we update the connector.status entry and only call _hotplug_event() when the status changes.

drm/bridge: adv7511: Use work_struct to defer hotplug handing to out of irq context

2017-09-09T15:39:42Z

commit 518cb7057a59b9441336d2e88a396d52b6ab0cce upstream. I was recently seeing issues with EDID probing, where the logic to wait for the EDID read bit to be set by the IRQ wasn't happening and the code would time out and fail. Digging deeper, I found this was due to the fact that IRQs were disabled as we were running in IRQ context from the HPD signal. Thus this patch changes the logic to handle the HPD signal via a work_struct so we can be out of irq context. With this patch, the EDID probing on hotplug does not time out.

drm/nouveau/pci/msi: disable MSI on big-endian platforms by default

2017-09-09T15:39:41Z

commit bc60c90f472b6e762ea96ef384072145adc8d4af upstream. It appears that MSI does not work on either G5 PPC nor on a E5500-based platform, where other hardware is reported to work fine with MSI. Both tests were conducted with NV4x hardware, so perhaps other (or even this) hardware can be made to work. It's still possible to force-enable with config=NvMSI=1 on load.

drm/ttm: Fix accounting error when fail to get pages for pool

commit 9afae2719273fa1d406829bf3498f82dbdba71c7 upstream. When fail to get needed page for pool, need to put allocated pages into pool. But current code has a miscalculation of allocated pages, correct it.

commit fd1adef3bff0663c5ac31b45bc4a05fafd43d19b upstream. The VSL and HSL bits in the DSMR register set the corresponding horizontal and vertical sync signal polarity to active high.

commit 9cdced8a39c04cf798ddb2a27cb5952f7d39f633 upstream. There is a bug in the setting of the DES (Display Enable Signal) register. This current setting occurs 1 dot left shift. The DES register should be set minus one value about the specifying value with H/W specification. This patch corrects it.

drm: rcar-du: Fix crash in encoder failure error path

2017-08-30T08:21:48Z

commit 05ee29e94acf0d4b3998c3f93374952de8f90176 upstream. When an encoder fails to initialize the driver prints an error message to the kernel log. The message contains the name of the encoder's DT node, which is NULL for internal encoders. Use the of_node_full_name() macro to avoid dereferencing a NULL pointer, print the output number to add more context to the error, and make sure we still own a reference to the encoder's DT node by delaying the of_node_put() call.
