Working on audio for qcom apq8098 / msm8998
Hello everyone,
I've been trying to get audio working on a qcom apq8098 (cousin of msm8998) board.
Code is mostly based on work from here: https://gitlab.com/msm8998-mainline/linux
This is the diff I have on top of v6.12-rc1 https://paste.debian.net/1331666/

Does anyone see something obvious I might have missed?

Looks like the audio DSP might not be correctly initialized?

Vendor kernel has no hits for hdmiif.

I haven't dug into audio. Not entirely sure how to help here.
0xee000000 is DDR on 8998. LPASS is at 0x17000000
lpass-lpaif could be LPASS_LPA_IF_REG_BASE at LPASS_BASE + 0x00100000 ?

Vendor kernel has no hits for hdmiif.
I don't see anything relevant downstream :(
Do I need to look at the HW block at address 0xee000000 ?
I haven't dug into audio. Not entirely sure how to help here.
0xee000000 is DDR on 8998. LPASS is at 0x17000000
#define LPASS_BASE 0xee000000 #define LPASS_BASE_SIZE 0x00800000 #define LPASS_BASE_PHYS 0x17000000
#define LPASS_LPASS_CC_REG_REG_BASE (LPASS_BASE + 0) #define LPASS_LPA_IF_REG_BASE (LPASS_BASE + 0x00100000)
What's this LPASS_BASE at 0xee000000? Virtual address?

Vendor kernel has no hits for hdmiif.
I don't see anything relevant downstream :(
Do I need to look at the HW block at address 0xee000000 ?
I haven't dug into audio. Not entirely sure how to help here.
0xee000000 is DDR on 8998. LPASS is at 0x17000000
#define LPASS_BASE 0xee000000 #define LPASS_BASE_SIZE 0x00800000 #define LPASS_BASE_PHYS 0x17000000
#define LPASS_LPASS_CC_REG_REG_BASE (LPASS_BASE + 0) #define LPASS_LPA_IF_REG_BASE (LPASS_BASE + 0x00100000)
What's this LPASS_BASE at 0xee000000? Virtual address?
$ git grep 17000000 arch/arm/boot/dts/qcom /* nothing for my vendor kernel DTS */
Hmm, virtual address, but for the LPASS FW? I'm really puzzled.

Hi Marc,
There are two ways you could enable MI2S audio via HDMI, 1. via ADSP, which is what you have in the DT. 2. by passing DSP directly configuring to LPASS MI2S registers.(this needs a speical tz firmware to allow cpu to access LPASS registers)
You need to do only one thing, not the both.
By looking at some of the errors i would suggest you to
1. check if the MI2S pins are correctly configured. 2. if MCLK and BITCLK for these are MI2S are configured correctly with the required clk rate. (Pl take a look at existing examples sdm845/8016...) 3. set the correct mixers to connect FE and BE dai links.(look at existing ucm files for hints)
thanks, Srini

Looks like the audio DSP might not be correctly initialized?

Right now, I'm thinking I might (??) need the code in sound/soc/qcom/lpass-cpu.c to be called.
$ git grep asoc_qcom_lpass_cpu_platform_probe sound/soc/qcom/lpass-apq8016.c: .probe = asoc_qcom_lpass_cpu_platform_probe, sound/soc/qcom/lpass-cpu.c:int asoc_qcom_lpass_cpu_platform_probe(struct platform_device *pdev) sound/soc/qcom/lpass-cpu.c:EXPORT_SYMBOL_GPL(asoc_qcom_lpass_cpu_platform_probe); sound/soc/qcom/lpass-ipq806x.c: .probe = asoc_qcom_lpass_cpu_platform_probe, sound/soc/qcom/lpass-msm8998.c: .probe = asoc_qcom_lpass_cpu_platform_probe, sound/soc/qcom/lpass-sc7180.c: .probe = asoc_qcom_lpass_cpu_platform_probe, sound/soc/qcom/lpass-sc7280.c: .probe = asoc_qcom_lpass_cpu_platform_probe, sound/soc/qcom/lpass.h:int asoc_qcom_lpass_cpu_platform_probe(struct platform_device *pdev);

Vendor kernel has no hits for hdmiif.
I don't see anything relevant downstream :(
Do I need to look at the HW block at address 0xee000000 ?
lpass-lpaif could be LPASS_LPA_IF_REG_BASE at LPASS_BASE + 0x00100000 ?
