From: Liviu Dudau <Liviu.Dudau@arm.com> "I managed to loose track of a few patches for HDLCD while focusing on Mali DP and found them again when investigating an issue with the way HDLCD behaves on teardown. They can go into drm-next for one of the v4.19-rcX if you're not going to do another pull request before the merge window." Signed-off-by:

This set of changes migrates Armada DRM from legacy modeset to atomic modeset. This is everything from the "Transition Armada DRM planes to atomic state" and "Finish Armada DRM transition to atomic modeset" patch sets as posted on drm-devel, excluding the "Finish Armada DRM DT support" series. These series did not evoke any comments - if there are any, these can be addressed via follow up patches. Developed and tested on Dove Cubox with xf86-video-armada including the overlay plane, and also tested with the tools in libdrm. Signed-off-by:

A bit larger this time around, due to introduction of "dpu1" support for the display controller in sdm845 and beyond. This has been on list and undergoing refactoring since Feb (going from ~110kloc to ~30kloc), and all my review complaints have been addressed, so I'd be happy to see this upstream so further feature work can procede on top of upstream. Also includes the gpu coredump support, which should be useful for debugging gpu crashes. And various other misc fixes and such. Signed-off-by:

The HDLCD engine needs an active plane while the CRTC is active, as it will start scanning out data from HDLCD_REG_FB_BASE once it gets enabled. Make sure that the only available plane doesn't get disabled while the CRTC remains active, as this will scanout invalid data. Signed-off-by:Liviu Dudau <liviu.dudau@arm.com>

The plane cleanup handler currently calls drm_plane_helper_disable(), which is a legacy helper function. Replace it with a call to drm_atomic_helper_shutdown() at removal time. The plane .destroy() handler now consisting only of a call to drm_plane_cleanup(), replace it with direct calls to that function. Signed-off-by:

Use drm_fb_cma_fbdev_init() and drm_fb_cma_fbdev_fini() which relies on the fact that drm_device holds a pointer to the drm_fb_helper structure. This means that the driver doesn't have to keep track of that. Also use the drm_fb_helper functions directly.

The udl kms driver writes messages to the syslog whenever some application opens or closes /dev/fb0 and whenever the user switches between the Xserver and the console. This patch changes the priority of these messages to debug. Signed-off-by:

spin_lock_irqsave and spin_unlock_irqrestore is inteded to be called from a context where it is unknown if interrupts are enabled or disabled (such as interrupt handlers). From a process context, we should call spin_lock_irq and spin_unlock_irq, that avoids the costly pushf and popf instructions. Signed-off-by:

All users of do_gettimeofday() have been removed, but this one recently crept in, along with an incorrect printing of the microseconds portion. This converts it to using ktime_get_real_timespec64() as a direct replacement, and adds the leading zeroes. I considered using monotonic times (ktime_get()) instead, but as this timestamp appears to only be used for humans rather than compared with other timestamps, the real time domain is probably good enough.

For hangs, dump copy out the contents of the buffer objects attached to the guilty submission and print them in the crash dump report. Signed-off-by:
-
Jordan Crouse authored
HLSQ, SP and TP registers are only accessible from a special aperture and to make matters worse the aperture is blocked from the CPU on targets that can support secure rendering. Luckily the GPU hardware has its own purpose built register dumper that can access the registers from the aperture. Add a5xx specific code to program the crashdumper and retrieve the wayward registers and dump them for the crash state. Also, remove a block of registers the regular CPU accessible list that aren't useful for debug which helps reduce the size of the crash state file by a goodly amount. Signed-off-by:

Capture the GPU state on a GPU hang and store it for later playback via the devcoredump facility. Only one crash state is stored at a time on the assumption that the first hang is usually the most interesting. The existing crash state can be cleared after capturing it and then a new one will be captured on the next hang. Signed-off-by:

Convert the existing GPU show function to use the GPU state to dump the information rather than reading it directly from the hardware. This will require an additional step to capture the state before dumping it for the existing nodes but it will greatly facilitate reusing the same code for dumping a previously captured state from a GPU hang.

Add the infrastructure to capture the current state of the GPU and store it in memory so that it can be dumped later. For now grab the same basic ringbuffer information and registers that are provided by the debugfs 'gpu' node but obviously this should be extended to capture a much larger set of GPU information.
