- Update HWPM driver to add HAL layer. This will allow support for multiple chips. - Add below data structure hierarchy for HWPM driver HWPM driver structure -> chip info struct -> ip info array -> perfmux/perfmon info array NOTE: To make commit message more legible, using "aperture" instead of "perfmux and/or perfmon" - Chip info structure contains - Array of IP info - HAL function pointers - IP info structure contains IP specific info - Number of instances - Number of apertures per instance - Aperture ranges, strides, static info array - Aperture dynamic arrays - Aperture info structure contains - Hw index - Physical address info - MMIO address info - Add separate IP info files - Create separate files that include logic for allowlist, memory buffer, resources, ip, regops to make functions more legible. - Move probe, ioctl and io functions to os/linux path. - Add fn, info, register and verbose debug log levels to controls debug messages - add debugfs node to update dbg_mask - Correct MGBE perfmux base address Jira THWPM-41 Change-Id: I8ffdaa657789e2a187cbb98502d0359bb57f9c54 Signed-off-by: Vedashree Vidwans <vvidwans@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nvidia/+/2651377 Reviewed-by: svc_kernel_abi <svc_kernel_abi@nvidia.com> Reviewed-by: Seema Khowala <seemaj@nvidia.com> GVS: Gerrit_Virtual_Submit
