This patch series introduces two new features, enhances existing
functionalities, and adds NVL support to the intel_pmc_core driver.
The first two patches add new attributes to improve Package C-state
debugging. The third and fourth patches refine current functionality
for better support. The fifth patch enables the intel_pmc_core driver
retrieves PMC information only for available PMCs. Finally, the last
patch adds support for Nova Lake platforms.
Xi Pardee (6):
platform/x86/intel/pmc: Enable PkgC LTR blocking counter
platform/x86/intel/pmc: Enable Pkgc blocking residency counter
platform/x86/intel/pmc: Use PCI DID for PMC SSRAM device discovery
platform/x86/intel/pmc: Add support for variable DMU offsets
platform/x86/intel/pmc: Retrieve PMC info only for available PMCs
platform/x86/intel/pmc: Add Nova Lake support to intel_pmc_core driver

Enable the Package C-state LTR blocking counter in the PMT telemetry
region. This counter records how many times any Package C-state entry
is blocked for the specified reasons.

Enable the Package C-state blocking counter in the PMT telemetry
region. This counter reports the number of 10 µs intervals during
which a Package C-state 10.2/3 entry was blocked for the specified
reasons.

Update the PMC SSRAM discovery process to identify the device using its
PCI Device ID rather than relying on a fixed PCI bus location. The
enumeration of integrated devices on the PCI bus is no longer guaranteed
to be consistent across CPUs.
On earlier platforms, the IOE and PCH SSRAM devices were hidden from the
BIOS, and the SOC SSRAM device is associated to telemetry regions from all
available SSRAM devices. Starting with Nova Lake, the IOE and PCH SSRAM
devices register their telemetry regions independently, meaning each
telemetry region is now linked to its corresponding SSRAM device. A new
ssram_hidden attribute has been added to the pmc_dev_info structure to
reflect this distinction.

Add support for handling different DMU Die C6 offsets across platforms.
The previous implementation assumed a uniform DMU Die C6 offset for all
platforms, which is no longer valid.

Update the Intel PMC Core driver to fetch PMC information only for
available PMCs. Previously, the driver attempted to retrieve PMC info
even when the corresponding PMC was not present.
This change aligns with recent updates to the Intel SSRAM Telemetry
driver. Starting with NVL, the SSRAM Telemetry driver is probed for
each individual SSRAM device. The prior implementation could not
differentiate between an unavailable PMC and one that had not yet
completed information retrieval. To resolve this, the PMC Core driver
now skips obtaining PMC info for unavailable PMCs.

Fits easily to one line. Though, I'm not sure if offset variable improves
things, more like it makes this more complex than it need to be. To me it
would look more straightforward to do just:
ret = pmt_telem_read32(pmcdev->pc_ep,
pmcdev->pkgc_ltr_blocker_offset + i,
...);

Use __free(pci_dev_put) instead of complicating the code flow.
Please remember to place the variable declaration at the place of
assignment (no = NULL; assignments with __free()). You may want to do the
__free() conversion in own patch preceeding this.

I wonder if it would be create a common helper as this looks practically
the same as pmc_core_pkgc_ltr_blocker_show() added in the previous patch?

Please don't use = NULL; pattern with __free() because it's dangerous in
some cases, please see the long comment in cleanup.h for details why.
Place the declaration where you do the assignment.

I'd elaborate this as some of the SSRAM devices are hidden in this case.
IMO, the "Flag to indicate whether" is pretty pointless, the C type
information pretty much indicates it's a flag.

This seems a bit dangerous approach if somebody forgets to add that
PMC_IDX_MAX. It would be better to do it with sizeof() for safety).

Isn't this same as:

ret = pmc_core_pmc_add(pmcdev, pmc_list[i]);

Perhaps split to three lines as this starts to grow a bit long.

It would be nice to progress towards consistent capitalization of hex
letters. This patch isn't even consistent within itself. My preference is
lowercase as it avoids the LONG CAPS BLOCK effect that is pretty imposing.
