[PATCH v3] drm/sun4i: mixer: Read id from DT
by Jernej Skrabec 12 Jul '18

12 Jul '18

Currently, TCON supports 2 ways to match TCON with engine (mixer in this case). Old way is to just traverse of graph backwards and compare node pointer. New way is to match TCON and engine by their respective ids. All SoCs with DE2 enabled till now used the old way, which means mixer id was never used and thus never implemented. However, for R40, only the new way will be used. To prepare for that, implement mixer id fetching from DT.

[PATCH V3 0/4] Add infrastructure for vblank and page flip events in vkms
by Rodrigo Siqueira 12 Jul '18

12 Jul '18

Currently, we are working to make VKMS pass in the kms_flip test (IGT). As a result, we made a series of changes in the module with the goal to meet some of the necessary steps required by kms_flip. This patchset comprises all the modifications needed to make kms_flip partially pass. Note that the patch "drm/vkms: Add framebuffer and plane helpers" add two dummy functions related to the plane which is necessary for the basic operation of the VKMS during the kms_flip. During the original discussion with Daniel, he suggests removing these dummy functions [1]; however, removing these functions results in errors during the execution of kms_flip. Finally, this patchset is based on: - [PATCH V2 0/5] drm/vkms: Updates to meet basic kms_flip requirements (https://www.spinics.net/lists/dri-devel/msg180544.html) - [PATCH V3] drm/vkms: Add vblank events simulated by hrtimers (https://www.spinics.net/lists/dri-devel/msg182600.html) [1] https://www.spinics.net/lists/dri-devel/msg182690.html Rodrigo Siqueira (4): drm/vkms: Add dumb operations drm/vkms: Add framebuffer and plane helpers drm/vkms: Add connectors helpers drm/vkms: Add vblank events simulated by hrtimers drivers/gpu/drm/vkms/Makefile | 2 +- drivers/gpu/drm/vkms/vkms_crtc.c | 95 +++++++++++++++ drivers/gpu/drm/vkms/vkms_drv.c | 28 ++++- drivers/gpu/drm/vkms/vkms_drv.h | 47 ++++++++ drivers/gpu/drm/vkms/vkms_gem.c | 179 +++++++++++++++++++++++++++++ drivers/gpu/drm/vkms/vkms_output.c | 20 ++++ drivers/gpu/drm/vkms/vkms_plane.c | 18 +++ 7 files changed, 382 insertions(+), 7 deletions(-) create mode 100644 drivers/gpu/drm/vkms/vkms_gem.c -- 2.18.0

[PATCH] drm/etnaviv: bring back progress check in job timeout handler
by Lucas Stach 11 Jul '18

11 Jul '18

When the hangcheck handler was replaced by the DRM scheduler timeout handling we dropped the forward progress check, as this might allow clients to hog the GPU for a long time with a big job. It turns out that even reasonably well behaved clients like the Armada Xorg driver occasionally trip over the 500ms timeout. Bring back the forward progress check to get rid of the userspace regression. We would still like to fix userspace to submit smaller batches if possible, but that is for another day.

[BUG 4.17] etnaviv-gpu f1840000.gpu: recover hung GPU!
by Russell King - ARM Linux 11 Jul '18

11 Jul '18

It looks like a bug has crept in to etnaviv between 4.16 and 4.17, which causes etnaviv to misbehave with the GC600 GPU on Dove. I don't think it's a GPU issue, I think it's a DRM issue. I get multiple: [ 596.711482] etnaviv-gpu f1840000.gpu: recover hung GPU! [ 597.732852] etnaviv-gpu f1840000.gpu: GPU failed to reset: FE not idle, 3D not idle, 2D not idle while Xorg is starting up. Ignore the "failed to reset", that just seems to be a property of the GC600, and of course is a subsequent issue after the primary problem. Looking at the devcoredump: 00000004 = 000000fe Idle: FE- DE+ PE+ SH+ PA+ SE+ RA+ TX+ VG- IM- FP- TS- So, all units on the GC600 were idle except for the front end. 00000660 = 00000812 Cmd: [wait DMA: idle Fetch: valid] Req idle Cal idle 00000664 = 102d06d8 Command DMA address 00000668 = 380000c8 FE fetched word 0 0000066c = 0000001f FE fetched word 1 The front end was basically idle at this point, at a WAIT 200 command. Digging through the ring: 00688: 08010e01 00000040 LDST 0x3804=0x00000040 00690: 40000002 102d06a0 LINK 0x102d06a0 00698: 40000002 102d0690 LINK 0x102d0690 006a0: 08010e04 0000001f LDST 0x3810=0x0000001f 006a8: 40000025 102d3000 LINK 0x102d3000 006b0: 08010e03 00000008 LDST 0x380c=0x00000008 Flush PE2D 006b8: 08010e02 00000701 LDST 0x3808=0x00000701 SEM FE -> PE 006c0: 48000000 00000701 STALL FE -> PE 006c8: 08010e01 00000041 LDST 0x3804=0x00000041 006d0: 380000c8(0000001f) WAIT 200 006d8: 40000002 102d06d0 LINK 0x102d06d0 <=========== We've basically come to the end of the currently issued command stream and hit the wait-link loop. Everything else in the devcoredump looks normal. So, I think etnaviv DRM has missed an event signalled from the GPU. This worked fine in 4.16, so seems to be a regression. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 8.8Mbps down 630kbps up According to speedtest.net: 8.21Mbps down 510kbps up
