30 hoursGCE: ARM64 Support: Add hw.pci.honor_msi_blacklist=0.William Carrel
This is required for MSI support on GCE ARM64 instances which is prerequisite to gve(4) not panicking at boot, and nvme(4) also has a real sad time without interrupts. Tested on a variety of c4a VMs. This is meant to be a temporary hack; long term fix would be to check for the hypervisor and quirk gve(4) device with PCI_QUIRK_ENABLE_MSI_VM.

When lkpi_80211_txq_tx_one() calls into the crypto offloading parts to possibly make space in the headroom, the beginning of our frame moves. We have to reset hdr after that call as otherwise later classifications based on the hdr->frame_control will fail or cause wrong classificaiton of packets. This makes sure frames will either be directly sent using (*mo_tx)() or use the correct tid for the correct queue. This helps to get rtwx8 packets flowing after BA was negotiated.

For consistency rename the "scheduled_txqs" tailq to "txq_scheduled" and add a lock per txq ("txq_scheduled_lock[]"). We use the "_bh" locking as this called from the device driver. This fixes panics due to concurrent access to the tailq, especially in between "first" and "remove" on the out-direction and between "insert" and "elem_init" on the in-direction. This was easily reproducible just running iperf3 at basic rates for a few seconds to minutes with multiple chipsets, not only rtw89.

cfg80211_chandef_create() gets passed a pointer to a cfg80211_chan_def. It seems that several users are passing in an uninitialized variable from the stack and expect cfg80211_chandef_create() to initialize it.

3 dayspci: add quirk to disable Function-Level Reset (FLR)Bjoern A. Zeeb
MediaTek mt76 WiFi cards are advertising FLR support but after issuing a FLR the chipset is gone. Add a quirk so we can disable FLR. The current reset code will automatically fall back to a power reset. This makes the card show up under bhyve where before it would just not be discovered at all. That should make wifibox work for it and will help development for a LinuxKPI based mt76 driver as found in framework laptops as no dedicated machine and constant reboots are needed anymore. We will likely need to add more PCI vendor/device IDs once we can test the other device IDs.

The code introduced abs_diff() as migrated from drm to standard linux headers. The LINUXKPI_VERSION check did not allow this to be visible by default in-tree. Make sure the v6.6 check is optional. drm-kmod always defines LINUXKPI_VERSION so this should be fine.

3 daysLinuxKPI: pci: implement [linuxkpi_]pcim_request_all_regions()Bjoern A. Zeeb
Factor out the pci_request_region() implementation into an internal function and make pci_request_region() a simple wrapperaround it. Likewise implement pcim_request_all_regions() as a loop calling pci_request_region() for each entry. In two cases which we returned an error before (bar index is valid but bar is not (no len), and neither IO nor MEM) we now reutrn success (nothing to do for us). Otherwise callers, especially pcim_request_all_regions() would error out for the wrong reasons. This seems to also match the expected behaviour of pci_request_region().

The problem lies in the pci_resource_len() call but not that the BAR length is tmeporary 0 but in that we call lkpi_pci_get_bar() with a true argument which will create the BAR resource for us and report the approriate length back. However, the later call to bus_alloc_resource_any() will then fail given the resource already exists. Restore the previous behaviour and let bus_alloc_resource_any() do the work. Adjust the return values from -ENODEV to -EBUSY to match callers expectations. In linuxkpi_pcim_request_all_regions(), like in linuxkpi_pci_request_regions(), filter out the -EBUSY errors as "not an error" and try the next bar. This also seems to be consistent with the expectations of the callers.

Add a helper function to validate that the bar is within a valid range and sprinkle that check also to other related functions.

A port using linux(kpi) header files but not using skbuffs is hitting the case that it cannot find opt_wlan.h. Give up to the idea that skbuff.h is only used by wireless drivers (or in-tree) and that IEEE80211_DEBUG (via opt_lwan.h) could autmatically compile in debug support. It is likely time to add a LINUXKPI_DEBUG knob in the near future (also for linuxkpi_debug or linuxkpi_debug_rcu). PR: 289268 (cherry picked from commit bc222e96d135687aea4e67ee9b11fb9490f42546)
