01:01 <mntmn> if anyone has ideas on how to work around imx8mq LCDIF glitches (at 1920x1080) when used together with NVMe, i'm all ears

01:01 <mntmn> but on a positive note, current sway can easily work with etnaviv + dcss + lcdif dual outputs

01:03 <marex> mntmn: configure NOC priorities maybe ? :)

01:05 <mntmn> marex: haha. well i tried that.

01:06 <mntmn> i understood now how the mechanism works. they call into TF-A using something like arm_smccc_smc(IMX_SIP_NOC, IMX_SIP_NOC_PRIORITY, NOC_CPU_PRIORITY, 0x80000300, 0, 0, 0, 0, &res);

01:06 <mntmn> i hacked in the call to arm_smccc_smc(IMX_SIP_NOC, IMX_SIP_LCDIF_PRIORITY, 0, 0, 0, 0, 0, 0, &res);

01:06 <mntmn> but it doesn't seem to make a difference, also i don't understand what it is supposed to do... there's close to zero information about this

01:07 <mntmn> i'm thinking more to patch NVMe or PCI somehow and make it less aggressive, if possible

01:07 <mntmn> still have to figure out which point of the transfer/protocol actually disturbs lcdif. could be anything

01:11 <marex> mntmn: you should be able to configure those same registers in U-Boot too
