2021-10-07ASoC: SOF: debug: Print out the fw_state along with the DSP dumpPeter Ujfalusi
The fw state can be an important information along with the DSP dump. Print it out before the dump.

The new SOF_DBG_DUMP_OPTIONAL flag can be used to mark a DSP dump that should only be printed when the SOF_DBG_PRINT_ALL_DUMPS sof_core_debug flag is set, otherwise it should be ignored and not printed.

Do not print the dump more than once to keep the kernel log cleaner in case of a firmware failure. When the DSP is rebooted due to suspend or runtime_suspend reset the flags to re-enable the dump prints. Add also a debug flag to print all dumps to get more coverage if needed.

2019-08-01ASoC: SOF: no need to check return value of debugfs_create functionsGreg Kroah-Hartman
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Also, if a debugfs call fails, userspace is notified with an error in the log, so no need to log the error again. Because we no longer need to check the return value, there's no need to save the dentry returned by debugfs. Just use the dentry in the file pointer if we really need to figure out the "name" of the file being opened.

Add debugFS files that can be used to expose DSP memories and and peripherals to userspace to assist with firmware debugging. Since we cannot rely on debugFS, errors are logged but don't stop execution. When a resource cannot be read in D3, it is optionally cached on suspend. Copying memories from IO will increase the suspend latency, this should only used in engineering builds w/ debug options. This part will have to be enhanced when support for D0ix states is provided, currently only D0 and D3 are supported.
