Explanation
Issue
#365requires distinct GPU temperature and usage values in ROG Control Center. The implementation enumerates display GPUs and builds per-device readings, with runtime-power filtering and BDF-based NVIDIA lookup. The reviewed test file only coversGpuTelemetrydefaults andGfxPowerconversions. It has no regression tests for PCI enumeration, firmware-GPU selection, per-device telemetry mapping, inactive-card filtering, or the UI reading list.

Do not assume that nvidia is always the dGPU, look at the ProArt P16 (H7607, RTX Spark)
Same for intel, asus has laptops wth intel arc dGPU

is determined by explicit GPU fan telemetry availability during the polling
loop, not GPU count or ASUS control-path checks in setup_system. Ensure valid

nvidia_active calculation and its conditional release_nvml call. After
collecting readings from the device probes, call release_nvml unconditionally so
handles opened during any probe are released before the next poll; keep the
existing readings construction unchanged.
- Line 620: Update the GPU model-name lookup around gpu_model_name to cache
results by stable device identity rather than only by path, while preserving the
existing AMD and udev lookup behavior. Invalidate cached entries when a device
is removed or its identity changes so replacements are re-resolved, and avoid a
permanent path-only cache.

returning from the enumeration function, using each entry’s dev_path and the
existing pci_bdf helper as the ordering key. Keep device discovery and
per-device telemetry unchanged, and perform the sort immediately before

fix(rog-platform): do not probe a GPU that is not runtime-active
I don't think the condition you are adding here would change anything from current behavior
feat(rog-platform): enumerate display GPUs and read each card by name
This commit does more than it claims. Split it
fix(rog-control-center): watch the firmware GPU for status notifications
This commit only ever renames all instances of "dgpu" to "gpu"?
I assume you already know this but I prohibit heavy use of AI here. I feel you may be overusing it more than I'd like here.
In addition to that, I want you to do a sanity-check that you are able to recreate GPU wake up by telemetry on current main and that ur first commit really does resolve that issue. If so, we can merge that one commit and leave out refactors for after. Perhaps I will clean up everything in the new UI and would also like to have less conflicts with the existing home page there
By this I mean we can get the fix into main and consider refactor and improvement on new ui |
You were right about the first commit. Main already skips the probe when the dGPU is not active, so that change did nothing. I dropped it. I also could not reproduce a telemetry wake on this G614PR. In my laptop Runtime D3 is off and the NVIDIA card has not suspended since boot because Xwayland is holding its DRM node. I split the rest into two commits: one enumerates display GPUs from PCI sysfs and marks the firmware card, the other adds a name and telemetry for each card. The notify commit was a rename. is_dgpu() now means that firmware card, so notify.rs is unchanged. I left the System page and the translations out, so this does not collide with the new UI. |

The udev scan called every NVIDIA card a dGPU and every Intel card an iGPU. That is wrong for Intel Arc and for a laptop whose only GPU is NVIDIA. Scan display-class PCI devices instead, and mark the one card that ASUS dgpu_disable applies to. Temperature and usage still go through the existing iGPU/dGPU pair. A device that is not runtime-active is not probed. Signed-off-by: Marco Scardovi <scardracs@disroot.org>
Issue OpenGamingCollective#365 needs a temperature and a usage for every card, including Intel Arc and an NVIDIA that is the only GPU. The System page still reads the old iGPU/dGPU pair; this adds the per-card list for the new UI. Signed-off-by: Marco Scardovi <scardracs@disroot.org>

Description
Hybrid laptops (issue #365, GA503R: 680M + RTX 3080 Max-Q) reported the wrong GPU temperature and usage, and after 6.5.0 the discrete GPU looked fine while the other stayed N/A. Classifying NVIDIA as always discrete and Intel as always integrated is wrong: NVIDIA can be the only GPU (RTX Spark / GB10) and Intel can be discrete (Arc).
Display-class devices are enumerated from
/sys/bus/pci/devicesand reported by name. Telemetry does not label them iGPU or dGPU. Probes skip a card that is not runtime-Active, and skip the firmware-controlled GPU whendgpu_disableis set, including when MUX leaves that GPU as boot VGA. A lone GPU is not firmware-controlled. NVIDIA next to another vendor is the ASUS firmware GPU; same-vendor pairs use the non-boot-VGA device.NVML is only a fallback for an Active NVIDIA device that has no hwmon/DRM reading (proprietary, open-rm, and DKMS share libnvidia-ml). The handle is kept for the process lifetime: opening and dropping it on every poll blocks runtime suspend on the NVIDIA open kernel module. A failed init is not cached.
ROG Control Center lists each GPU by name. Suspended and Disabled replace the temperature and usage numbers. Tray notifications and the GPU mode page still follow
dgpu_disable/gpu_mux_mode.Fixes #365
