<DC-IRC> [Discord] <ideallykafei> Only using 2 of the 3 npu cores
<DC-IRC> [Discord] <lanefu> I just think the NPUs on those SoC are basically for CV uses and nothing else
<DC-IRC> [Discord] <ideallykafei> Realistically if i did end up using it it would be for computer vision but i think it would be fun to see any other uses
<DC-IRC> [Discord] <liwei19920307> Hey, guys
<DC-IRC> [Discord] <liwei19920307> Why can't I find the option to boot from emmc in the new version of armbian-install
<DC-IRC> [Discord] <pjack1212> does anyone know why the vendor kernel for rk3568 doesnt show any temp and therma_zone is missing( under sys/class and virtual ...)
<DC-IRC> [Discord] <pjack1212> on current it exist and on old 5.1 kernel(radxa debian ) it existed to
<DC-IRC> [Discord] <igorpec> it seems eMMC detection is not right. Report here https://github.com/armbian/build/pull/6958
<DC-IRC> [Discord] <Werner> With the switch to rkr3 Radxa zero 3E might got broken. Need to retest tomorrow. Mainline, edge with 6.10.2 still works fine.
<DC-IRC> [Discord] <Werner> Anyone here with a 3E or 3W to verify?
<DC-IRC> [Discord] <zeeto9> I’ll agree with this, but for computer vision at the edge, the 6 tops can do a lot. I think this is an issue with many consumers. They don’t understand what and npu is or what it SHOULD be used for. Cutting out all the hype of ai/llm, computer vision is the one useful area for these npu’s and are excellent for it.
<DC-IRC> [Discord] <dams0869> Does anyone know why the screen saver under gnome shows me a black screen instead of turning off the screen? I'm running the mainline kernel 6.10
<DC-IRC> [Discord] <dams0869> Under arch with the vendor kernel it turns off the screen...
<DC-IRC> [Discord] <dams0869> Heloo, does anyone know why the screen saver under gnome shows me a black screen instead of turning off the screen? I'm running the mainline kernel 6.10
<DC-IRC> [Discord] <dams0869> Under arch with the vendor kernel it turns off the screen...
<DC-IRC> [Discord] <dams0869> Hello, does anyone know why the screen saver under gnome shows me a black screen instead of turning off the screen? I'm running the mainline kernel 6.10
<DC-IRC> [Discord] <dams0869> Under arch with the vendor kernel it turns off the screen...
<DC-IRC> [Discord] <igorpec> "under arch with vendor kernel". This means you need to use Armbian with vendor kernel
<DC-IRC> [Discord] <igorpec> which is 1st and recommended download target
<DC-IRC> [Discord] <igorpec> with a reason
<DC-IRC> [Discord] <dams0869> ok, thank
<DC-IRC> [Discord] <jonh7776> I'm still fighting with the video modes on the 6.1-rkr3 kernel. Thus far it appears to be a clock rounding related issue. I put in some code to print out the internals of vop2_crtc_mode_valid in rockchip_drm_vop2.c and the modes being filtered out fail the final test for accurate HDMI clocks since the input value doesn't match the rounded value. This rounded value comes from rock <clipped message>
<DC-IRC> [Discord] <jonh7776> chip_drm_dclk_round_rate.
<DC-IRC> [Discord] <jonh7776> As an example, for 5120x1440 the requested clock is either 483.4 or 547.86 Mhz. The rounded clock is 396 Mhz. That appears to be capped more than rounded but for the 3840x2160 resolution the requested clock is 594 Mhz and that is accepted at 594 Mhz.
<DC-IRC> [Discord] <jonh7776> This doesn't seem to make any difference whether the 8k overlay is loaded or not.
<DC-IRC> [Discord] <jonh7776> The 2560x1440 modes fail also for similar rounding mismatch problems. Even though 2560x1440 is clearly lower than the 4k resolution which works ok and can be used by the way. I think I see a pattern to when the mismatches occur and next I'm going to run an experiment to test that out.
<DC-IRC> [Discord] <jonh7776> Anything about this ringing any bells out there? 🙂
