- HWPM driver requires to know if an IP is available for performance measurements. The ideal way is for IP driver registration with HWPM driver. This way IP driver can share required power management and register access function pointers. - For IPs that do not have registration mechanism implemented, a workaround to set an IP enabled is implemented in the HWPM driver. - In the recent releases, MSS channel, PVA and DLA IPs are the only PORs for production builds. Currently, this is acheived using the combination of minimal build and force enable flags. - However, this implementation limits the number of enabled IPs on TOT to only minimal expected ones. - This patch modifies the force enable IP logic implementation to make force enable and minimal IP flag definition more clear. - CONFIG_T234_HWPM_ALLOW_FORCE_ENABLE should be used to purposely enable IPs that do not have registration mechanism implemented. This flag is used for POR or non-POR IPs. Ideally, all IPs should implement HWPM registration and force enable flag should not be required. - CONFIG_TEGRA_HWPM_MINIMAL_IP_ENABLE should be used to implement logic for POR IPs. In other words, if CONFIG_TEGRA_HWPM_MINIMAL_IP_ENABLE is not defined, non-POR IPs should be included in the builds. This patch sets MINIMAL IP config only for external non-safety builds. - Fix include t234_perfmon_device_index.h error in t234_mss_mcf.c file. - Add missing device index for PVA perfmon C0.

# One of the HWPM components is a perfmux. Perfmux registers belong to the
|
|
# IP domain. There are 2 ways of accessing perfmux registers
|
|
# - option 1: implement HWPM <-> IP interface. IP drivers register with HWPM
|
|
# driver and share required function pointers
|
|
# - option 2: map perfmux register address in HWPM driver
|
|
# Option 1 is the preferred solution. However, IP drivers have yet to
|
|
# implement the interface. Such IPs can be force enabled from HWPM driver
|
|
# perspective (option 2). Marking an IP available forcefully requires the user

# to unpowergate the IP before running any HWPM experiments.
