2019-08-23drm/panfrost: Fix possible suspend in panfrost_removeRob Herring1-2/+4
Calls to panfrost_device_fini() access the h/w, but we already done a pm_runtime_put_sync_autosuspend() beforehand. This only works if the autosuspend delay is long enough. A 0ms delay will hang the system when removing the device. Fix this by moving the pm_runtime_put_sync_suspend() after the panfrost_device_fini() call.

2019-08-23drm/i915: switch to drm_fb_helper_remove_conflicting_pci_framebuffersGerd Hoffmann1-39/+2
No need for a home-grown version, the generic helper should work just fine. It also handles vgacon removal these days, see commit 1c74ca7a1a9a ("drm/fb-helper: call vga_remove_vgacon automatically."), so that can be removed too.

Since commit b0e999c95581 ("fbdev: list all pci memory bars as conflicting apertures") the parameter was used for some sanity checks only, to make sure we detect any issues with the new approach to just list all memory bars as apertures. No issues turned up so far, so continue to cleanup: Drop the res_id parameter, drop the sanity checks. Also downgrade the logging from "info" level to "debug" level and update documentation.

2019-08-21drm: kirin: Fix for hikey620 display offset problemDa Lv2-0/+23
The original HiKey (620) board has had a long running issue where when using a 1080p montior, the display would occasionally blink and come come back with a horizontal offset (usually also shifting the colors, depending on the value of the offset%4). After lots of analysis by HiSi developers, they found the issue was due to when running at 1080p, it was possible to hit the device memory bandwidth limits, which could cause the DSI signal to get out of sync. Unfortunately the DSI logic doesn't have the ability to automatically recover from this situation, but we can get a an LDI underflow interrupt when it happens. To then correct the issue, when we get an LDI underflow irq, we we can simply suspend and resume the display, which resets the hardware. Thus, this patch enables the ldi underflow interrupt, and initializes a workqueue that is used to suspend/resume the display to recover. Then when the irq occurs we clear it and schedule the workqueue to reset display engine.

2019-08-19drm/panfrost: Implement per FD address spacesRob Herring9-87/+236
Up until now, a single shared GPU address space was used. This is not ideal as there's no protection between processes and doesn't work for supporting the same GPU/CPU VA feature. Most importantly, this will hopefully mitigate Alyssa's fear of WebGL, whatever that is. Most of the changes here are moving struct drm_mm and struct panfrost_mmu objects from the per device struct to the per FD struct. The critical function is panfrost_mmu_as_get() which handles allocating and switching the h/w address spaces. There's 3 states an AS can be in: free, allocated, and in use. When a job runs, it requests an address space and then marks it not in use when job is complete(but stays assigned). The first time thru, we find a free AS in the alloc_mask and assign the AS to the FD. Then the next time thru, we most likely already have our AS and we just mark it in use with a ref count. We need a ref count because we have multiple job slots. If the job/FD doesn't have an AS assigned and there are no free ones, then we pick an allocated one not in use from our LRU list and switch the AS from the old FD to the new one.
