The latest linux-rpi4/5 kernels and rpi5-eeprom packages has been pushed to the unstable branch when the mirrors sync.
The rpi5-eeprom package has some preliminary work for network install which we do not use in latest but it is there if some one wants to do a network install of PiOS. Most of us use default so really no big reason to flash the pi5 eeprom.
They finally upgrade 6.7-rc6 to 6.7-rc8 but that is still 2 weeks behind. I decided to not waste my time with it as 6.7.1 could possibly hit at any time upstream.
I have both compiled and tested. 6.6.13 sees to be good. 6.7 has a reboot/shutdown issue. It will lock up toward the end of the boot before the login screen and When I pull the power and pluf power back it goes through fsck then boots ok but the next boot it will go through the same process again. If you want to deal with that I will post 6.7 also with 6.6.13. I never tested it on the pi4 though. It may be different.
@Rip2 I will have to wait for RPi to add it to their gitlab tree. It’s no small job merging their tree with upstream. They have a ton of their own patches and they do a git rebase every week.

I finally got around to testing the linux-rpi4-mainline 6.7.1-1 kernel package and they seem to be ok unlike the broken linux-rpi5-mainline 6.7.1-1 package. My router quit working yesterday.
@Dulbi the linux-rpi4-mainline 6.7.1-1 kernel has BCACHEFS_FS module enabled if you are wanting it for the pi4.
The eeprom packages has an update in latest regarding image and FAT compatibility which most of us use default so no big reason to flash the eeprom until it makes it to default.
I am going to open an issue with linux-rpi5-mainline 6.7.1-1 today on their github.

Could not create Vulkan device:

Wonder if something has to be enabled in mesa-git config or are you sure they are supposed to work. Looking up the errors it seems that if it is not mesa then the gpu does not support it.
Pi vulkan-1.2 supported only, so pass to CPU do the jobs that what they said or i misunderstand?
kernel, mesa, vulkan-demo?
can you test VKdoom for double check?
edit,
6.8-rc1 note did not seen any v3dv things, maybe not merge?

drm/v3d: Free the job and assign it to NULL if initialization fails
I am rebuilding mesa-git today. I looked over the configure logs and it was searching for an installed v3dv3 package which it did not find.
I found this 3 year old guide to build v3dv by Igalia. At that time it was merged into the mesa tree in a separate branch. So will have to do some more searching to try some type of updates with it.
mesa-24 highlight, wait 6.8-RC? to test.
Maíra Canal (22):
v3dv: implement VK_EXT_multi_draw
v3dv: move multisync functions to the beginning of the file
v3dv: allow different in/out sync queues
v3dv: allow set_multisync() to accept more wait syncobjs
drm-uapi: extend interface for indirect CSD CPU job
v3dv: check CPU queue availability
v3dv: create a CPU queue type
v3dv: use the indirect CSD user extension
v3dv: occlusion queries aren’t handled with a CPU job
drm-uapi: extend interface for timestamp query CPU job
v3dv: use the timestamp query user extension
drm-uapi: extend interface for reset timestamp CPU job
v3dv: use the reset timestamp user extension
drm-uapi: extend interface for copy timestamp results CPU job
v3dv: use the copy timestamp query results user extension
drm-uapi: extend interface for the reset performance query CPU job
v3dv: don’t start iterating performance queries at zero
v3dv: use the reset performance query user extension
drm-uapi: extend interface for copy performance query CPU job
v3dv: use the copy performance query results user extension
v3d/v3dv: move V3D_CSD definitions to a separate file
v3dv: enable CPU jobs in the simulator
They are still trying to get things right with 6.8-rc2. They aborted their last “Compile Tests” Friday. I usually do not see much activity on their github on the weekends.
I have compiled and tested their latest and for some reason the schedutil governor is not scaling the cpu cores. It seems to be stuck at 600MHz. Everything else seems to be working ok as far as I can see. I got the scaling to work by installing cpupower and then ran this command:
sudo cpupower frequency-set -g ondemand
You can monitor the cpu/temp with this command in a terminal:
cpu-temp-speed
I still have no clue how to test the new cpu-jobs. I have the mesa 24 git version installed I posted above. Bottom line is if you want to test the kernel on your pi4 here it is. Just be sure you install cpupower and enable the ondemand govenor as shown above to have the cpu threads scaling.
