00:31 <MoeIcenowy> smaeul: hacked D1 libdram to let it contain no Xthead instr

00:43 apritzel has quit [Ping timeout: 480 seconds]

00:44 <smaeul> MoeIcenowy: oh, good! does that mean the whole SPL now runs without enabling Xthead?

00:45 <smaeul> and if you are interested, please send a PR to https://github.com/smaeul/sun20i_d1_spl

00:47 <MoeIcenowy> well I think some cache code still uses Xthead

00:47 <MoeIcenowy> BTW just disabling MAEE seems to be not enough to allow kernel w/o MMU extension to run

00:47 <MoeIcenowy> (MAEE is the switch of MMU extension in mxstatus reg

00:48 <smaeul> do you mean it still traps when enabling the MMU?

00:48 <MoeIcenowy> I got a few lines of earlyprintk, and then trap

00:50 <MoeIcenowy> BTW the cache instruction may get replaced by an operation to MCOR reg

00:51 <smaeul> well a few lines is more than I was expecting. I wonder if the bus non-coherency breaks even UART

00:51 <smaeul> maybe it will work if you globally disable the data cache

00:52 <MoeIcenowy> BTW I cleanup Xthead mainly to ease Ghidra

00:54 <smaeul> ah, the fun part :)

00:54 <smaeul> were you able to make use of any of the DWARF info?

00:55 <MoeIcenowy> well, at least type info

00:56 <MoeIcenowy> and now I have experience on R329/V831 DRAM ;-)

00:57 <smaeul> does it look similar?

01:02 <smaeul> anyway, good luck on the reversint!

01:02 <smaeul> *reversing

02:15 <swiftgeek> I feel like my HDMI issues are coming from HPD handling

02:16 <swiftgeek> but instead of fixing software, I think I will just pull it up permanently

02:16 <swiftgeek> on monitor side

03:24 <swiftgeek> k, it's floating inside

03:24 <swiftgeek> HDMI calls for 1kΩ so i will go with that

04:43 <swiftgeek> yep, that was it

04:57 <swiftgeek> but u-boot still doesn't like it lol

18:58 <smaeul> I'm going down the rabbit hole of PINCTRL/DM_GPIO conversion, and there actually is some non-SPL use of legacy I2C (grep for CONFIG_VIDEO_LCD_I2C_BUS)

18:59 <smaeul> I'll send a patch for this
