May be a dumb question but can I just change the ring size in the peripheral?

Somewhat similar to this #12

The text was updated successfully, but these errors were encountered:

Hi,

The ring size is SoC specific; I'm not sure if the SoC you are using has been tested by us.
Either way, for adjusting, I would suggest to change the according SoC definition, located in https://github.com/FirmWire/FirmWire/blob/main/firmwire/vendor/mtk/soc/__init__.py

The variables to adjust should be SHM_QUEUE_NUM and SHM_LAYOUT; Our definition for the MT6765 seems to follow that layout.

If you have a new SoC and it works after adding a definition, we'd happily look forward to a pull request :)

@mariusmue
How do I determine what goes in SHM_LAYOUT?
I was able to get rid of the error by appending zeroes and increasing SHM_QUEUE_NUM to 17 since the value that is used to index the ringbuffer is 16 but now readPacket() returns None which causes an error.

Here is the firmware: https://drive.google.com/file/d/1sxwNvbu79noHNy4NtQSprBglU8EajYjP/view?usp=sharing

I tried enabling debug for the peripheral but I don't know what to do?
Attached gdb did not work either when I use "-s" then started gdb and then "target remote :1234"

You need to check the corresponding Linux kernel source.

For the MT6765, you can look at https://github.com/xiaomi-mt6765/android_kernel_xiaomi_mt6765/blob/lineage-17.1/drivers/misc/mediatek/eccci/hif/ccci_hif_ccif.c - but the only other values there seem to be equivalent to our MT6768 config. Did you try just copying that one directly? (Or do you have kernel source matching your firmware?)

thanks for your response.
the kernel version is

MT6765 
4.9.190+
QKQ1
Oct 1, 2020 patch level

When I try this the error is ERROR] firmwire.hw.peripheral.PCCIF_Periph.PCCIF0_MD: PCCIF ring no too large (value: 16, is only: 8) so I had changed it the one with 16 instead but then I get
ERROR] firmwire.hw.peripheral.PCCIF_Periph.PCCIF0_MD: PCCIF ring no too large (value: 16, is only: 16)

I tried appending a 0 to each and changing SHM_QUEUE_NUM from 16 to 17 but then ring.readPacket() receives None irmwire/vendor/mtk/hw/PCCIFPeripheral.py line 495.

Also in the binary amms_pccif_read_from_buffer goes to secpccif_read_sram - is the ring buffer the emulator using in the sram?
