Subject: [PATCH v8 0/2] Add debugfs node to expose G-state and pcie link state residency
Date: Sat, 28 Jun 2025 00:30:39 +0530 [thread overview]
Message-ID: <20250627190041.238015-1-soham.purkait@intel.com> (raw)
This patch exposes G-state and pcie link state residency counter
values through debugfs. The debugfs node "dgfx_pkg_residencies" exposes
G-states counters (G2, G6, G8, G10, ModS) and "dgfx_pcie_link_residencies"
exposes PCIe link states(L0, L1, L1.2) residency counters.
Example:
$ cat /sys/kernel/debug/dri/<bdf>/dgfx_pkg_residencies
Package G2 : 42853454
Package G6 : 26564
Package G8 : 705212205
Package G10 : 0
Package ModS : 396016642
$ cat /sys/kernel/debug/dri/<bdf>/dgfx_pcie_link_residencies
PCIE LINK L0 RESIDENCY : 12336019
PCIE LINK L1 RESIDENCY : 2326635578
PCIE LINK L1.2 RESIDENCY : 2326632312
