hi yall. am i right that the only current way to get video out of a m1 pro mbp is the hdmi port?
<blackMysticCat>
found my answer on the sub.. should have searched harder. lol. thanks
<blackMysticCat>
found another question -- what is the highest resolution/refresh rate you can squeeze out of a M2 Pro/Max/Ultra MBP? I can get 5120x2160 @ 30Hz (from the m1 pro mbp hdmi, which I've read is HDMI 2.0, as opposed to the m2's HDMI 2.1)

blackMysticCat: Display with the largest resolution tested under Linux is the Dell 6k one. In general it should work in the same way as under macos and support the advertised resolutions. I'm still unsure if Apple has a trick to bridge the gap between DP HBR3 (32 gbps) and HDMI 2.1 (48 gbps) or if it has to rely on DSC for higher resolution, framerate, pixel format combinations
<chadmed>
iirc leio had to patch out the pixel clock thing to get DSC working on his studio, at which point the higher res/refresh rates worked
<chadmed>
did we end up dropping that?

yeah, 6144x3456 at 60 Hz is what I got fine after dropping that limit (in asahi kernels now) and getting a quality HDMI cable that says 8K on it; was U3224KBA, but can NOT recommend that monitor, unless you use it only in very bright environments with high brightness setting
<leio>
I wonder how 4K@240Hz compares in terms of bandwidth
<leio>
huh, some calculator tells me with DSC 4K@60 4:4:4 has more bandwidth requirement in 8-bit than 10-bit
<jannau>
4k 240Hz requires more bandwidth. number of pixels increases only by factor ~2.5
<leio>
question being, if the current HDMI support could drive it as such

I broke my asahi fedora with a failed update, grub can't find the kernel
<DarkShadow44_m>
It should have the new kernel installed, but points to the old one..
<DarkShadow44_m>
Any way to fix this without reinstall?
<jannau>
leio: 4k 144Hz 10-bit 4:4:4 works
<jannau>
Darkshadow44_m: are you sure it can't find the new kernel and not just the initramfs for the new kernel
<jannau>
Darkshadow44_m: press escape immediately after you see "Booting: nvme 0". that should enter the grub menu and and you can select the old kernel
<DarkShadow44_m>
It says the file /initramfs-6.8.10-400.asahi.fc40.aarch64+16k.img is not found
<DarkShadow44_m>
Not sure I know the difference, tbh

Darkshadow44_m: The kernel is the kernel. Initramfs file is a way to give the kernel some kernel modules and tools to be able to mount real rootfs (e.g. it can include additional host controller drivers, LVM or full disk encryption tools etc). Initramfs can be linked in the kernel image during kernel assembly or can be supplied externally by the bootloader.
<DarkShadow44_m>
Alright, thanks
<PaulFertser>
Darkshadow44_m: usually when a new kernel is installed along with it's modules in /lib/modules/ a tool like update-initramfs or dracut or something is called to generate a new initramfs image with the kernel modules for that version. If it failed to do the job you got an error during upgrade, you shouldn't have ignored it but fixed before rebooting.
<PaulFertser>
For now just use GRUB menu to boot older pair of kernel+initramfs and fix from a running system.
<DarkShadow44_m>
Will try, once I get my mac to cooperate
<PaulFertser>
s/it's modules/its modules/
<jannau>
Darkshadow44_m: there is a performance regression in the program creating the initramfs. It can several minutes instead of seconds. Once you got the system to boot `dracut --kver 6.8.10-400.asahi.fc40.aarch64+16k` should cretae the file and the default boot should work again

Hello, is there a way to install a 4k kernel on Fedora?
<Slendi>
I want to get FEX to work
<j`ey>
Slendi: no, you use a VM for that
<Slendi>
Is there graphics hardware acceleration if I do a VM?
<j`ey>
if you set everything up, krun, virgl etc

jannau: Yes that Dell 6K one is the one Im testing rn. The 5120x2160 resolution is too small for my eyes, so in macOS It can drop to 3840x1620 which is perfect (except for being at 30Hz). That isn't an option for asahi though -- the only 'native' resolutions it shows are all stretched etc besides 5120x2160. So for linux (in hyprland but plasma isn't really different) I've been using the 5120x2160 in scaled factor 1.3333. Which would work fine
<blackMysticCat>
(excluding Xorg stuff) but its @30Hz. I'm not sure if it should be 30Hz or 60Hz for the 5k2k on linux through hdmi (on the m1 pro mbp). Thinking about getting an M2 Pro/etc but I'm not sure if that's my problem, as I have been having issues with the monitor on hdmi on every OS. I'm returning this one to see if another has the same problem

that's a WUHD, not 6K

c10l has joined #asahi
<leio>
WUHD is the width of 5K, but less pixels in height, so not even 5K. That is all to say, that thing should need quite a bit less bandwidth than the 6K that worked for me on a 6K monitor with M2 Ultra
<leio>
They really market this thing as a 5K2K? mmkayy....
prompath has quit [Quit: Page closed]
<leio>
I guess not as bad as USB naming and actually makes some sense :) Check what HDMI cable you have, I had to upgrade to really pull off 6K@60, and that'd be a "hardware" issue that'd affect all OS and other GPUs too
<blackMysticCat>
I don't know if they market it as such, I just thought that :P
<blackMysticCat>
I have tried several hdmi cables, including some that Im sure are 2.1
<blackMysticCat>
From what I've read though, M1 Pro MBP only puts out hdmi 2.0
<blackMysticCat>
That said I'm having hdmi issues even on macOS
<blackMysticCat>
(even on low resolutions)
<leio>
the link janna_u gave indeed suggests hdmi 2.1 is needed for the native resolution at 60Hz
Brainium has joined #asahi
<leio>
in macOS your 3840x1620 is probably running the display at 5120x2160 and hence the 30Hz.
<leio>
the other resolutions it generally shows are really just hidpi scaling represented as "looks like WxH 100% scale" instead of a scaling factor.
<blackMysticCat>
What's strange is its only showing 30Hz even for as low as 1600 x 675. Does that seem right?
<leio>
yes, macOS tells you what it looks like, not what it drives the monitor at
<leio>
the monitor is always at native resolution
<blackMysticCat>
ugh. so that works on m2 ultra asahi but shouldnt on m1 pro asahi?
<blackMysticCat>
Thats a weird way to do it
<leio>
I agree, but maybe because so used to a scaling factor display
<leio>
As I didn't really have those problems on my device, I haven't looked, but maybe on macOS something like BetterDisplay or that other popular one I don't remember might be able to convince to switch the monitor output to a lower resolution to get 60Hz. And presumably on macOS you could use a different connector that should support up to 6K@60
blackMysticCat has quit [Quit: ...the mystic black cat has taken a nap...]
<leio>
getting a bit off-topic on the macOS bits though. I personally can not for sure tell you that you can't do it with m1 pro over current HDMI. But you should be able to force the monitor to a lower resolution with ease on asahi linux and with that go 60Hz.
<jannau>
on asahi the monitor might offer other modes. `cat /sys/class/drm/card*-HDMI-A-1/modes` or drm_info
<leio>
the specs tell 6K@60 is supported, so IF the HDMI is 2.0 and doesn't support it, then it must be for Thunderbolt or some such. I bet a internet search engine will be revealing on that :)
<leio>
various articles suggest M2 Pro and Max do HDMI 2.1 too
<jannau>
usb-c dp altmode or dp over thunderbolt is enough for 5120x2160 60Hz (4:4:4 10-bit) and DP supports dsc while hdmi 2.0 doesn't

Yeah I've been looking around on google/reddit but didn't have any luck. I'm going to try a different (lower spec'd) monitor and see if that works. No point in buying a high spec'd monitor If you can't use it. Works fine for macOS over usb-c etc but obviously not an option for linux yet. I was hoping this would be an alternative to waiting for two monitor support, but apparently it will be a waiting game either way, unless asahi supports the
<blackMysticCat>
lower res on the other one.
<blackMysticCat>
That said, and more on the asahi side of things, if you were getting a new MBP, and wanted to have the most support now and in the future for asahi, which would you go for?
<blackMysticCat>
*most support and higher specs*
