Commit Message

  In a SoC based solution, it would be useful to know the versions of the
various binary firmware blobs the system is running on. On a QCOM based
SoC, this info can be obtained from socinfo debugfs infrastructure. For
this to work, respective subsystem drivers have to export the firmware
version information to an SMEM based version information table.

Having firmware version information at one place will help quickly
figure out the firmware versions of various subsystems on the device
instead of going through builds/logs in an event of a system crash.

Fill WLAN firmware version information in SMEM version table to be
printed as part of socinfo debugfs infrastructure on a Qualcomm based
SoC.

This change is applicable only for WCN399X targets.

Example:
cat /sys/kernel/debug/qcom_socinfo/cnss/name
QC_IMAGE_VERSION_STRING=WLAN.HL.3.2.2.c10-00754-QCAHLSWMTPL-1

Reported-by: kernel test robot <lkp@intel.com>

Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.2.2.c10-00754-QCAHLSWMTPL-1

Changes from v2:
 - Removed blank line between trailers
 - Changed memcpy to strscpy
 - Removed version_string_size
 - Added new condition fw_build_id against max length

Why is this restricted to WCN399X? Is it not the case that it only
relates to the SNOC/QMI-based implementation? Perhaps that's the same
thing, but if so I think the comment could be improved.

I don't think that kernel test robot reported the lack of this feature.

This isn't the ATH10K SMEM_IMAGE_VERSION_TABLE, it's the one and only
SMEM_IMAGE_VERSION_TABLE. As that is defined in socinfo.c, you can
use the same define here.

I don't think "smem" or "ptr" adds any value in this variable name.
"table" should be sufficient.

This is the "smem_item_size".

Why not just "offset"?

#define SMEM_IMAGE_VERSION_ENTRY_SIZE 128

Instead of writing 128 here and abusing MAX_BUILD_ID_LEN below.

You found a IMAGE_VERSION_TABLE, but it's smaller than expected. That
sounds like an ath10k_err() to me.

Is this really a concern, if the string is too long strscpy() below will
truncate it.

MAX_BUILD_ID_LEN is the length of fw_build_id, which is 128.

But the memory you're writing to is defined as:

struct smem_image_version {
	char name[SMEM_IMAGE_VERSION_NAME_SIZE];
	char variant[SMEM_IMAGE_VERSION_VARIANT_SIZE];
	char pad;
	char oem[SMEM_IMAGE_VERSION_OEM_SIZE];
};

With SMEM_IMAGE_VERSION_NAME_SIZE being 75.

qmi->fw_build_id is only valid if resp->fw_build_id_valid is set...

Is there a reason why you used "depends on"? Other QCOM dependencies
used "select", so I'm wondering if QCOM_SMEM should also use select?

Please also use ath10k list for ath10k patches, not ath11k.

Sure Kalle. As suggested will change it to select.
