06:53 <macc24> robclark: i see no lmh mention in cros trogdor kernel FYI

08:46 <shawnguo> steev: I have just taken out LMh patch set from laptops-5.13 branch. In the native deb-pkg build, it locks up machine completely.

10:48 <shawnguo> Added a little document for kernel rebuild and upgrade - https://github.com/aarch64-laptops/debian-cdimage#kernel-upgrade

14:21 <steev> shawnguo: i sent a mail to thara (and the mailing list) about lmh, hoping she replies, the driver is very nice

14:22 <steev> shawnguo: oh nice, thanks for the pointer on the dtbs :D

14:48 <steev> shawnguo: out of curiosity, do you see the rcg clk not getting updated in your 5.13?

17:39 <derzahl> mattst88: no, encrypted/compressed zfs actually came in a hair faster than plain ext4. the 30%+ increase in compile speed was on zfs, using the lmh patch

17:51 <mattst88> ah, okay

18:28 <macc24> i don't know if this is smart or just stupid either way it works xD https://i.imgur.com/gxP7xRv.jpeg

19:32 <derzahl> attaching a sata drive to udb? why wouldnt it work?

21:09 <mattst88> oh yeah, I've done that kind of thing :)

21:10 <mattst88> I installed Windows on an external drive like that just so I could update the thunderbolt firmware on a laptop dock :|

21:22 <macc24> why does 5400rpm 2.5" hdd feel as fast as emmc

21:24 <robclark> if you are talking about lazor, emmc is currently slower than it should be.. apparently iommu.strict=0 helps (but otoh you probably want modem/wifi to be strict, and setting iommu.strict on kernel cmdline changes the setting globally)

21:24 <macc24> why would i want modem iommu to be strict

21:25 <robclark> so some potential fw bug doesn't corrupt memory mostly

21:25 <macc24> i like living on the edge

21:26 <robclark> rough idea is that peripherals who's dma access is controlled by the kernel, it is safe to not use strict.. things where there is firmware involved in memory access, you probably want to be strict

21:26 <robclark> it ofc depends on your threat model

21:27 <robclark> for dev device which doesn't have my ssh/pgp keys, non-strict for everything is probably ok

21:29 <robclark> I think there might have been also some iowait/boost tuning that also helped w/ emmc?

21:29 <macc24> huh
