how to vc4 graphics on aarch64 pi4?

[gofree]

will try later this week - busy with some other stuff - If it will work I'll buy you a beer just kidding - is there a way to send you few bucks to support arm arch - edit. found it, done it

No need to pay me anything; I do this to give back to the community and personal reasons. I'm sure donating to the official project would be welcomed.

the cpu usage went from 70perc to 30perc - so I guess its far better ( guess the alarm7 is even lower , but its a very good start and might be usable )

packages installed from the repo you posted...ill give it a spin for a week or so to see how it perfoms longterm

any chance that mesa 20.3 could help ?

gonna search if there is a libcec-rpi how to for rpi4 64bit - till than Ill stick with bluetooth keyboard instead of TV remote

yes, kodi playback for multimedia simultaneously rpi is acting as samba, running couple containers, jupter notebook , etc - like I said 30perc its huge improvement against 70perc from this point Im staying on aarch64 fron now on

to libcec I had to to adjust arm7h libcec-rpi pkgbuild to aarch64 and its working now ( standard libcec for aarch64 didnt work ) - maybe I just overlooked something

big thanks to you for the work you've done so far ! aarch64 is way to go

Your post prompted me to try building libcec-rpi for aarch64 and then to rebuild kodi against it. Good to hear that the rebuild is superfluous and that just dropping in the package works.

I did install latest packages from your webhost today - libcec is loaded ( O can see it in kodi ) but the TV remote is not working. I guess this the price of beta version of kodi , etc. Keep up the work, I'm not complaining - I feel more like a tester and giving feedback. I'll install new releases when they'll be ready and report ( or I can provide logs , etc, if youd like )

Thanks

I can't rule out something on my side causing the issue. If you have a spare SD card, you can try out the beta version of libreelec. If CEC works there, something on my end is to blame.

EDIT: I don't think kodi is the problem...

On armv7h (with 5.10.0.rc5-7)

On aarch64 (with 5.10.0-rc5-7):
$this->bbcode_second_pass_code('', '

So the problem is likely with libcec-rpi not kodi...

Is it possible to use this kernel and boot using usb storage?
