How to run FreeBSD on new boards built on Rockchip 35XX..

Im trying to add sound to rk356x boards. the existing dma driver did not worked and i fixed it

I'm interested for sure. Can you explain what should I do to fix it ? Until now I have postponed the problem while I'm working on the rewriting of the panfrost driver for FreeBSD 15 on the radxa zero,but I saw that the sound part didn't want to compile succesfully so,I have disabled all the options related to sound and midi :

Code: 
nooptions SND_PCM
nooptions SND_DEV
nooptions SND_HDA
nooptions SND_MIDI
nooptions SND_SEQ
nooptions SND_TIMER
nodevice sound
nodevice snd
nodevice midi
nodevice pcm
nodevice hdac
nodevice hda

But I never thought that it didn't work on 14.x because I never tested sound.

He said, "Let there be sound"
There was sound

I have it working both PIO and DMA. I went PIO out of more pl330 dma frustration but in the end it works with DMA too.
I have no idea how pl330 worked with this code in older rk socs but it seems borderline impossible to me. maybe the wiring was somehow different or the targeted peripherals were more friendly.
Ill post the patches here in the following days (the code needs some minor cleaning)
 
Code: 
pl3300: <ARM PrimeCell DMA Controller (PL330)> mem 0xfe530000-0xfe533fff irq 49,50 on ofwbus0
pl3300: We have apb_pclk clock
pl3300: Mode: NON Secure, Channels :8, Peripherals: 32, n_evts: 16, peri_reg: ffffffff evts_reg: 0000ffff quirks: 00000002
pl3301: <ARM PrimeCell DMA Controller (PL330)> mem 0xfe550000-0xfe553fff irq 51,52 on ofwbus0
pl3301: We have apb_pclk clock
pl3301: Mode: NON Secure, Channels :8, Peripherals: 32, n_evts: 16, peri_reg: ffffffff evts_reg: 0000ffff quirks: 00000002
rk_i2s_tdm0: <Rockchip I2S/TDM Controller> mem 0xfe400000-0xfe400fff irq 43 on ofwbus0
rk_i2s_tdm0: Rockchip I2S/TDM controller initialized
rk_i2s_tdm0: Playback: yes, Capture: no
rk_i2s_tdm1: <Rockchip I2S/TDM Controller> mem 0xfe410000-0xfe410fff irq 44 on ofwbus0
rk_i2s_tdm1: Rockchip I2S/TDM controller initialized
rk_i2s_tdm1: Playback: yes, Capture: yes
rk817c0: <RockChip RK817 Audio Codec> at addr 0x40 irq 81 on iicbus0
rk817c0: Enabling audio route MIC
rk817c0: Disabling audio route SPK
rk817c0: Enabling audio route HP
 
here it is.
tested on orange pi 3b / rk3566
the rk817_codec is somehow hackish because its in the same chip as the pmic so it has the same i2c address
one solution would have been to shove the code in the pmic driver but it looked ugly to me
so if you add option RK817_CODEC to the kernel then rk817 pmic driver will create a iic bus child device for the codec
there is still a problem that they have the same phandle (no separate dts entries) and if both the pmic and the codec want to
OF_device_register_xref crap will happen.
fortunately as of now the pmic does not xref itself. audio dai code needs xref for simple-audio-card,codec

I plan to configure the audio on my radxa zero 3W following this tutorial :


They say :

Note: currently the HDMI audio is not working out-of-box on our official image. You will need to manually install this package to have it working. We will add it to our official image in a later time once we know the package won't negatively affect existing users.

So. Do I need to use your patches if I want to hear sounds using HDMI ?
 
Hello to everyone.

I ported the panfrost driver on FreeBSD 15.0 for my radxa zero 3W board. I mean,I've been able to fix all the errors I found and I compiled correctly the kernel and the modules. Unfortunately,when I tried to boot it,this is what happened :

It is stuck there. My sensation is the problem can be fixed easily. But I need to understand why. What could be the reason,what to try and so on.

Anyway,I want to share the source code of the kernel ,the compiled kernel and the modules,if someone wants to study the code and try on his board :
