Overview & identity
The 1002:1636 entry carries CHIP_RENOIR and AMD_IS_APU. It is an integrated-graphics family match, not a precise CPU model or laptop identity. The APU flag explains why a discrete-card assumption about local video memory is inappropriate without reading the system configuration.

pci 1002:1636
A numeric match establishes a candidate family within the reviewed evidence. Marketing names, board variants, subsystem conditions and successful operation remain separate questions.
Driver & binding
amdgpu is the table-backed candidate and the graphics source declares renoir firmware. On a system with another GPU, keep the render and display roles distinct: the APU may drive a panel while an application renders elsewhere. A firmware request from a different PCI address should not be assigned to Renoir just because amdgpu is shared.

Firmware
Host-loaded firmware required
The reviewed amdgpu engine declares the listed images. They are examples for this family, not a complete package manifest. Use the exact firmware request from the running kernel to identify a missing file; a file merely existing on disk does not establish successful loading.
Checked examples or filename branches, not a complete installation list:
amdgpu/renoir_pfp.binamdgpu/renoir_mec.bin
Read-only diagnostics
Run one displayed command at a time. Replace uppercase placeholders with the affected device, interface or module from your own output. Commands are never executed here. Read-only output can still contain private identifiers.
Read the numeric PCI identity and binding
lspci -nnk -s BDFReplace BDF with the address of the Renoir integrated graphics display function. No sudo is normally required for this summary. The numeric vendor/device pair is the evidence for identity; “Kernel driver in use” is evidence of the current binding. A “Kernel modules” list is only a list of candidates.
Confirm the owner of this PCI function
readlink /sys/bus/pci/devices/BDF/driverUse the full domain:bus:slot.function address in BDF, for example the form shown by lspci -D. This read-only symlink normally needs no elevated privileges. Its last component names the bound driver. An absent link can also mean an unbound, removed or guest-assigned function; it does not prove that no Linux driver exists.
Read initialization and failure context
journalctl -k -b --no-pagerRead the first amdgpu initialization or engine-failure messages, including the requested firmware filename and any recovery that follows. This reads the current boot only. Correlate the PCI address and timestamps before connecting a message to this GPU. Journal access depends on local group permissions; a permission error is not a hardware result.
Limitations & related issues
Neither the ID nor an AMD_IS_APU flag predicts battery life, memory reservation or suspend reliability. Firmware loading, application selection and a failed suspend callback require different evidence; no reproduced notebook-specific fix is asserted.
