Re: [PATCH v12] PCI: Add device-specific reset for Qualcomm devices

Hi Bjorn,

Gentle ping on this patch. It has Mani's Reviewed-by and has
been tested over 100+ VM reset cycles for both WLAN and modem
devices.

This patch adds device-specific reset for Qualcomm PCIe devices
(WCN6855, WCN7850 WLAN and SDX62/SDX65 modems) that lack working
reset methods for VFIO passthrough. The reset uses BAR-space
hardware registers, replicating the sequences from ath11k/ath12k
and MHI drivers. Without this, these devices cannot be reused
after an unclean VM termination.

The approach follows Alex's guidance through the series:
device-specific reset via pci_dev_reset_methods[] (suggested
in v5), and BAR-space hardware reset registers instead of
D3hot power cycling (refined with Mani from v10 onwards).

The quirk_no_bus_reset part was already merged for v7.2, and
this device-specific reset completes the solution.

Is there anything else needed for this to be considered?

Thanks,
Jose Ignacio
