- try_mem now returns Result (matching caller expectations)
- try_map_bar: non-panicking BAR mapping on PciFunctionHandle
- try_pci_allocate_interrupt_vector: non-panicking IRQ allocation
- virtio-core: reverted .ok_or() back to .map_err() for Result type
Added try_mem() returning Option<(usize, usize)> for non-panicking
memory BAR access. Fixed virtio-core/probe.rs to use .ok_or() instead
of .map_err() to match the Option return type.
Per local/docs/PATCH-PRESERVATION-AUDIT-2026-07-12.md the base
fork was carrying only 38 of 100 patches in local/patches/base/.
The other 62 patches' content was silently missing from the fork
working tree, even though their .patch files were preserved.
This commit re-applies 41 patches that genuinely still apply
cleanly + 17 hunks that partially applied. Recovery covers:
- D-Bus initfs service wiring (P4-initfs-dbus-services)
- USB service wiring (P4-initfs-usb-drm-services)
- netcfg/dhcp/dhcpv6 driver fixes
- acpid shutdown/PM/quirk fixes
- inputd/ps2d hard-fail logging
- pcid driver interface refinements (server cmd channel)
- virtio-core for VirtualBox support
- ixgbed/rtl8139/rtl8168 net drivers
- ahcid NCQ + per-function interrupt coalescing
- logd persistent logging
- bootstrap procmgr race-condition fixes
- cargo version pin to +rb0.3.0 (synchronized release branch)
58 files changed, +1444/-318 lines.
Untracked mnt/ tree and *.orig / *.rej files cleaned up after
patch application (leftover from absolute-path patch headers).
This way PCI drivers don't need to use the privileged physmap interface,
but only need access to a pcid handle. This is not yet enough for
running drivers as unprivileged processes. Interrupts also need
privileges and we need IOMMU support in the kernel.
