Nov 27 22:31:59 <ubptgbot> <minlexx> drebrez: do you mean this - https://github.com/minlexx/android_kernel_samsung_msm8974/commit/be5c7deab5eb8ee67100993e26ebdc1bd9d3a7a3?
Nov 27 22:35:56 <ubptgbot> <minlexx> drebrez: I can't explain in 2 words, I'm not near PC now (vacation), but I'll try to document my thoughts in Halium klte issue thread as soon as I get home.
Nov 27 22:37:03 <drebrez> @minlexx no problem, take your time. Yes it was about that commit
Nov 27 22:37:53 <ubptgbot> <minlexx> (Photo, 957x1280) https://irc.ubports.com/Dw0iEgCk.png
Nov 27 22:37:54 <drebrez> instead of patching, in postmarketos I used the kernel parameter `androidboot.boot_recovery=1` because there was other places where it looks for that

Nov 27 22:39:52 <ubptgbot> <minlexx> @minlexx, Linux logo (penguin) during boot
Nov 27 22:40:08 <drebrez> when I compiled the lineageOS, I had problem writing to the framebuffer, at the beginnig because of the issue you mentioned about failing to reserve memory, but that was fixed increasing a kernel config option
Nov 27 22:40:16 <ubptgbot> <UniversalSuperBox> How ironic
Nov 27 22:40:25 <ubptgbot> <UniversalSuperBox> The framebuffer never works on Qualcomm devices
Nov 27 22:41:15 <ubptgbot> <minlexx> @minlexx, Plasma logo displayed by userspace program using framebuffer
Nov 27 22:41:50 <drebrez> @UniversalSuperBox it has various problems but somehow works
Nov 27 22:42:10 <ubptgbot> <UniversalSuperBox> Yes, that's the irony
Nov 27 22:42:15 <ubptgbot> <minlexx> https://github.com/minlexx/test framebuffer here is the source of test program
Nov 27 22:42:15 <ubptgbot> <UniversalSuperBox> This device where nothing has gone right
Nov 27 22:42:18 <ubptgbot> <UniversalSuperBox> Has framebuffer
Nov 27 22:42:45 <drebrez> @minlexx FYI: in the next days I try to continue mainlining the samsung klte
Nov 27 22:44:35 * drebrez sent a long message:  < https://matrix.org/_matrix/media/v1/download/matrix.org/NEdgvDjuvjmqMvayBSVwIYlK >
Nov 27 22:45:13 <drebrez> but after that I had timeouts and memory page faults when writing to the framebuffer, dunno why
Nov 27 22:53:26 <ubptgbot> <minlexx> Several hacks are needed (from https://github.com/minlexx/test_framebuffer/blob/master/main.c) to make it actually work from userspace ( MSMFB_DISPLAY_COMMIT ioctl)
Nov 27 22:56:33 <drebrez> @minlexx you can also use the PAN ioctl, in postmarketOS we run a little tool borrowed from AsteroidOS => https://github.com/AsteroidOS/msm-fb-refresher
Nov 27 22:56:34 <ubptgbot> <minlexx> @UniversalSuperBox, One more funny fact, I found kernel option to enable DRM interface for gpu driver (off by default). I tried it and got device /dev/dri/card0
Nov 27 22:56:57 <ubptgbot> <UniversalSuperBox> @minlexx, o.o
Nov 27 23:01:51 <ubptgbot> <minlexx> @drebrez> @minlexx you can also use the PAN ioctl, in postmarketOS we run a little tool borrowed from AsteroidOS =, Interesting, good to know that
Nov 27 23:22:14 <drebrez> @minlexx if you are interested, here is my small tool to test the framebuffer https://gitlab.com/postmarketOS/pmaports/blob/master/main/fbdebug/fbdebug.c
Nov 27 23:24:08 <drebrez> I also have a version to draw on it, not an external image but something like the SMPTE color bars
