Re: [PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

Having another quick search now had revealed the Hummingboard Edge, which has 2GB RAM and M.2, although I've not found a UK reseller yet. That seems like it could be another good choice? On Mon, Apr 24, 2017 at 10:18 AM, Dan MacDonald wrote: > Hi Phillip > > Do you think

Re: [PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

Hi Phillip Do you think there is any hope for us getting the GPU to work on my Element14 SABRE Lite or is it a lost cause, with it being such a rare board combined with my lack of of kernel dev skills and limited dev time for this? I'm sure I'll find a non-GPU dependent use for the SL if that is

Re: [PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

Hi Philipp Is there any more info regarding my display probs that you need from me? Are you working on or do you plan to create another revision of this patch? I am presuming I'm the only person on this list who owns the Element14 version of the SABRE Lite? Thanks On Wed, Apr 5, 2017 at 3:18

Re: [PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

It took just under 11 hours to build the Arch 4.11 armv7h kernel on my SL. The good news is that the patch both applied and built OK this time, and the kernel package installed fine. What didn't seem right is that boot pauses for a minute or so on these lines: [ 4.458572] panel-simple panel-lcd:

Re: [PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

Hi Phillipp Thanks for the patch, but did you mean v4.11-rc4 or is it really/only for v4.11-rc1, if it makes a difference? I was trying to build rc4. Thanks On Mon, Apr 3, 2017 at 12:46 PM, Philipp Zabel wrote: > Hi Dan, > > On Sat, 2017-04-01 at 11:50 +0100, Dan

Hi Phillipp My SL was attached to a 27" UHD Acer S277HK Monitor. I can disable those for the next patch but I get the impression thats not the only issue here as I've gone from being able to get a picture (but not the right res) in 4.10 to not getting any HDMI signal at all with this patch.

Re: [PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

I should've said that 4.10 didn't pause at: [ 4.458572] panel-simple panel-lcd: panel-lcd supply power not found, using dummy regulator [ 4.467736] panel-simple panel-lvds0: panel-lvds0 supply power not found, using dummy regulator If it showed those lines at all and I've never seen those

Thanks Russell! I think the patch has applied OK - I've just started the build so it could be a while yet. 12 hours maybe? Its building support for every arm7 thing under the sun because I'm too lazy (sensible?) to try hacking it down to size. Adding the patch to the Arch rc kernel PKGBUILD was

No such luck. The patch I used (against 4.11-rc4) is attached. The error was: SHIPPED arch/arm/boot/compressed/bswapsdi2.S AS arch/arm/boot/compressed/bswapsdi2.o LD arch/arm/boot/compressed/vmlinux OBJCOPY arch/arm/boot/zImage Kernel: arch/arm/boot/zImage is ready Building

Hi all Up until now I've only ever used the most basic features of git, so I've had to do some research into how to best/cleanly extract Phillipps patches so that I can include his changes into an Arch kernel PKGBUILD. I think the following should work: git clone

Hi Philipp I moved house again on Sunday - that is the second time in two months. I won't bore you with the details but it means I've not had much time to myself recently and why I've not been able to test this patch. As I was saying previously, the only way I can reliably test this is to do it

Re: [PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

I think the easiest (if definitely not the fastest) way for me to test these patches the Arch way IF they will apply cleanly against 4.11-rc1 is to patch the linux-armv7-rc PKGBUILD so that it will apply Phillipp's patches before it builds the kernel. The linux-armv7-rc PKGBUILD is available

Re: [PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

Thanks for your tips and links Philipp and Russell! My distro of choice is Arch and so really I should try to install the patched git kernel "the Arch way" so my first question is, does anyone on this list have an Arch PKGBUILD script to create a linux (4.x) git kernel package for imx6 alikes?

Hi Phillipp I did suspect I would have to check out another repo first but I wasn't sure which. Is that 4th command: git checkout -b "branchname" FETCH_HEAD The exact command I should run? "branchname" sounds a bit generic. Thanks On Mon, Mar 6, 2017 at 1:50 PM, Philipp Zabel

[PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

Hi, this series fixes an issue with the IPU DC/DP/IDMAC disable sequence. The interrupt waiting code didn't work as expected, sometimes causing busy waits longer than the timeout in drm_atomic_helper_wait_for_vblanks, which would cause crashes similar to the reported "imxdrm issue on SABRE Lite"
