Qualcomm QCA6390 PCIe family

An ath11k PCIe device with an MHI/QMI-backed initialization path. A visible PCI function may still be waiting for target firmware or board data.

Overview & identity

17cb:1101 is QCA6390_DEVICE_ID in the PCI table. Probe also reads the SoC hardware version before selecting the reviewed hardware path.

Curated identifiers
pci 17cb:1101

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

ath11k_pci is the candidate transport. The source maps QCA6390 hw2.0 to its own firmware directory; inspect initialization progress rather than treating enumeration as successful boot.

  • ath11k_pci — kernel driver/module candidate

Firmware

Host-loaded firmware required

The checked firmware directory or filename is family/revision specific. The complete requested files and board data must be read from the running system.

Checked examples or filename branches, not a complete installation list:

  • ath11k/QCA6390/hw2.0/*

Inspect firmware packaging on your distribution

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 selected PCI function

lspci -nnk -s BDF

Replace BDF with the address from your report. Compare Kernel driver in use with Kernel modules; only the former records binding. This ordinary query normally needs no root privileges.

Read firmware metadata

modinfo -F firmware MODULE

Replace MODULE with ath11k_pci or the actual candidate module in your report. Metadata lists declared filenames; it does not prove a file was loaded. This query needs no root privileges.

Read existing Wi-Fi association

iw dev INTERFACE link

Replace INTERFACE with the wireless interface from iw dev. Association and rate are observations, not a throughput or firmware test. This query normally needs no root privileges.

Limitations & related issues

The pair does not certify a laptop integration, working resume or usable regulatory channels. Firmware availability and radio state need host evidence.

These guides are linked for relevant observations, not as known defects of every device in this family.
