base: re-sync ACPI userspace with upstream master
Phase B of the ACPI fork-sync plan (local/docs/ACPI-FORK-SYNC-STRATEGY-2026-06-30.md).
Pairs with the kernel fork-sync commit 4f2a043.
Restores the base fork to match upstream Redox OS base master for the
ACPI userspace:
- Cargo.toml (workspace):
* Add acpi = { git = "...redox-os/acpi.git", branch = "redox-6.x" }
workspace dependency. The jackpot51/acpi GitHub fork was
deprecated in favor of the gitlab.redox-os.org fork that
tracks the redox-6.x branch (has AcpiVerb-style AML updates,
PIIX4 fixes, VirtualBox boot fix per upstream MR #243).
* Switch redox_syscall from crates.io 0.8.1 to a git ref of
gitlab.redox-os.org/redox-os/syscall.git, with [patch.crates-io]
redirecting crates.io consumers to the gitlab fork. The
crates.io 0.8.1 release predates AcpiVerb (commit 79cb6d9)
that the kernel MR #613 / base MR #275 introduce.
- drivers/acpid/Cargo.toml: acpi.workspace = true.
- drivers/amlserde/Cargo.toml: acpi.workspace = true.
- drivers/hwd/Cargo.toml: add redox_syscall.workspace = true
dependency. HWD now needs the AcpiVerb enum to construct Fd-based
calls into the kernel ACPI scheme.
- drivers/amlserde/src/lib.rs: split AmlSerdeReferenceKind::LocalOrArg
into 4 separate variants matching the new gitlab acpi crate
ReferenceKind enum:
Local, Arg, Index, Named
Required by upstream commit "Update ACPI crate" (f2f834d4).
- drivers/acpid/src/main.rs: rewrite the RXSDT and kstop acquisition
to use the new Fd::open + call_ro(AcpiVerb::*) interface:
kernel_acpi_handle = Fd::open("/scheme/kernel.acpi", O_CLOEXEC, 0)
rxsdt = kernel_acpi_handle.call_ro(buf, READ, &[ReadRxsdt])
shutdown_pipe = kernel_acpi_handle.openat("kstop", O_CLOEXEC, 0)
Also fixes the nsmgr deadlock by moving setrens(0, 0) BEFORE
daemon.ready() (upstream commit 9dd6901d).
- drivers/hwd/src/backend/acpi.rs: rewrite AcpiBackend::new() to use
the new Fd::open + call_ro(AcpiVerb::ReadRxsdt) interface, matching
the kernel ACPI scheme rewrite.
