Fwd: Re: [Differential] D43399: VCHIQ HDMI AUDIO 64 bits BCM2835, BCM2711 Raspberry Pi 4B; correct minor compile errors. bcm2835_audio.c

For VCHIQ HDMI and analog Audio. Do not use patch D43399. use just the 3 Marcos Devesas Campos patch files. Patch in this order, D36431, D37878, D37879. Compile kernel for Freebsd at /usr/src
time make -j4 buildkernel KERNCONF=GENERIC-VCHIQ -DNO_CLEAN

time make installkernel KERNCONF=GENERIC-VCHIQ

Specific detailed instructions on the January 19, 2024 ghostbsd-arm64.blogspot.com post and reviews.freebsd.org/D43399 post

Enjoy sound on your Rasberry pi 4B,3B,400 today. Will have an Ghost14*Jan22_*.img.xz for GhostBSD-Arm64 up at http://ghostbsdarm64.hopto.org/packages/ that plays HDMI audio sound on VCHIQ hardware on Broadcom chip.

There is shell script file to 1.) download Freebsd-14.0-RELEASE*RPI.img.xz or 2.) Ghostbsd-Arm64 img.xz file.

3.) download a URL you paste there

Decompress file.img.xz into file.img

dd write file into usb flash drive /dev/da1

http://ghostbsdarm64.hopto.org/packages/write_freebsd_img_dd_to_da1.sh

Glad to share with you "the sound of music" playing on your RasPi vchiq hardware.

JSM do these 3 patches work on Raspberry Pi 5 hardware. Thanks for your effort to make microSD card hardware operational on RasPi 5.

ps. Experienced errors writing to 128GB Kingston USB flash drive connected to USB blue 3.0 sockets.

fsck -y /dev/da1p3

reports fixing inode errors

fsck -y /dev/da1p3 again shows same inode errors

So be careful and check. Mark Millard thanks for heads up with USB 3.0 errors.

Do not need patch file at D43399, when using those 3 patch files.

D36431, D37878, D37879 patch files from Marcos

I successfully compiled the kernel and verified that sound can be produced through the 3.5mm headphone jack. However, it appears that sound is still not being produced through HDMI? In my device, only one PCM device (3.5mm) is visible.

Created a blogpost specifically about applying a patch code from 

D36431, D37878 and D37879 review.freebsd.org



https://ghostbsd-arm64.blogspot.com/2024/01/hdmi-audio-sound-patches-into-ghostbsd.html



I also posted here too: To keep same info from my blogpost available 

in reviews.freebsd.org

You can look, I mentioned you. Maybe I should remove your email 

address, Yan-Hao Yang? I am asking your permission. I will remove on 

you say so. Maybe I go remove now. Fred

Now to patch the code and test the patch.

Yes, I have sound coming out the HDMI Audio speakers on the Samsung TV. 

Look at the blog post up above. Thanks for your interest and spurring 

me on to try again make the HDMI sound work. Yan-Hao Wang.

No I did not make any changes.



I also incorporated most of that blog post changes into your Fxx 

image.png post at

https://reviews.freebsd.org/F75131370



So people reading this can try patching the kernel software and hearing 

sound from the Raspberry Pi 4B VCHIQ hardware on the HDMI Audio output
