03:09 <smaeul> there is a manual for the CPU in the D1: https://occ.t-head.cn/vendor/cpu/download?id=3817197695983423488

03:10 <smaeul> but I can't manage to download it -- I assume because I have no Chinese mobile number

03:13 <smaeul> btw the D1 manual seems to support this claim of there being a dual-core ARM CPU inside: https://www.cnx-software.com/2021/04/29/allwinner-processor-2021-2022-roadmap-allwinner-t827-t723-and-t1033-socs/#comment-582368

17:42 <megi> now I guess it's only time before the first D1 boards appear

17:44 <megi> I wonder what performance to expect compared to similarly clocked A53

17:45 <megi> hmm, looks like aw was forced to use 5.4, because backporing risc-v arch support to 3.4 would be too hard?

17:46 <smaeul> they were previously using 4.9. still that seems to be the likely reason

17:52 <megi> it's quite a jump anyway

17:53 apritzel has quit [Ping timeout: 252 seconds]

18:09 <megi> ah, looks like tkaiser did some benchmarks already

18:13 <megi> looks about 2.5 slower than H3 in AES benchmark

18:21 <megi> not a number cruncher, but it may be power efficient :)

18:29 <megi> bad benchmark, armv7 is using optimized assembly, and riscv code is just generic compiled C code https://github.com/openssl/openssl/tree/master/crypto/aes/asm

18:55 <jernej> megi: did you see how big stock cooler is on RISC-V BeagleBoard? :)

18:56 <jernej> but it's a different core, so one from AW might still be more efficient

20:23 <megi> I didn't :)

20:50 <tuxd3v> does any one knows how to glue toguether the xorg.conf + mesa Lima driver?

20:51 <tuxd3v> I mean what is the config for Xorg.conf

20:54 <sunshavi> tuxd3v: It should work out of the box with xorg-server-git

20:54 <tuxd3v> hello sunshavi how are you?

20:54 <tuxd3v> does you sure that we don't need nothing in xorg.conf?

20:55 <tuxd3v> I am not using the git version, intead using the packaged one for debian

20:55 <sunshavi> tuxd3v: I could share my Xorg.log

20:55 <tuxd3v> please, if you don't bother :)

20:56 <tuxd3v> I am building it now, and it does require more dependencies than before..

20:56 <tuxd3v> I am building '21.0.3'

20:58 <sunshavi> https://termbin.com/eld49

21:01 <sunshavi> tuxd3v: https://termbin.com/oxcnx

21:04 <tuxd3v> many thanks,

21:04 <tuxd3v> so you don't have nothing in xorg.conf, you are using wayland right?

21:05 <sunshavi> no wayland

21:05 <sunshavi> I use just openbox over X
