Red Bear OS

The I2C transfer chain was stubbed end-to-end: - i2cd's transfer path returned 'not implemented yet' for every transfer, and its wire format didn't match the only in-tree consumer (i2c-hidd sends a bare I2cTransferRequest, i2cd expected I2cControlRequest::Transfer). - intel-lpss-i2cd / dw-acpi-i2cd / amd-mp2-i2cd registered an adapter name and parked forever without initializing the controller or executing a transfer. - intel-lpss-i2cd matched only legacy ACPI HIDs, which do not exist on Meteor Lake / Arrow Lake platforms (LPSS I2C binds by PCI ID there, per Linux drivers/mfd/intel-lpss-pci.c). Replace with real implementations: - New shared crate drivers/i2c/designware (dw-i2c): DesignWare I2C master engine ported from Linux 7.1 i2c-designware-master.c and i2c-designware-common.c — IC_CON + SCL timing computed from ic_clk with Linux's exact hcnt/lcnt formulas (bxt_i2c_info 133 MHz for LPSS, 100 MHz for ACPI-designated blocks), SDA hold with RX-hold workaround, polling transfer engine with RESTART/STOP sequencing, TX_ABRT decode (Nack/arbitration-lost/abort/timeout), 7/10-bit addressing, bounded timeouts. Also provides the shared /scheme/<name> transfer endpoint with register-then-ready ordering. - intel-lpss-i2cd: PCI discovery for ARL-H (0x7750/0x7751, 0x7778-0x777b) and MTL-P (0x7e50/0x7e51, 0x7e78-0x7e7b) with 32/64-bit BAR0 decode, ACPI alias resolution via FixedMemory32 == BAR0 across /scheme/acpi/resources, legacy ACPI-HID path kept, i2cd registration with bounded retry, serves /scheme/i2c-lpss. - dw-acpi-i2cd: converted from register-and-park to the shared engine, serves /scheme/dw-acpi-i2c. - i2cd: real transfer routing — adapter resolution by name/alias (exact, normalized, last-component) and forwarding to the provider daemon's /scheme/<provider>/transfer endpoint. - i2c-interface: I2cAdapterInfo gains provider_scheme + aliases (serde-default, wire-compatible). Tests: dw-i2c 3, intel-lpss-i2cd 3; full workspace cargo check clean; base cooks for x86_64-unknown-redox. Refs: local/docs/LG-GRAM-16Z90TP-COMPATIBILITY-PLAN.md Phase 4

# Red Bear OS Phase I: s2idle / Modern Standby support.

# The [patch.crates-io] replaces the upstream gitlab.redox-os.org
|

# redox_syscall (which lacks the new AcpiVerb::EnterS2Idle /
|
|
# ExitS2Idle variants) with the local fork at
|
|
# local/sources/syscall/ (a sibling directory of base/, both
|
|
# under local/sources/). The local fork is the upstream
|
|
# gitlab.redox-os.org/redox-os/syscall @ 79cb6d9 with our
|
|
# Red Bear OS P1 commit (cfa7f0c) on top. The version field
|
|
# stays at upstream 0.8.1 — periodic rebase via
|
|
# 'git fetch upstream && git rebase upstream/master' is the
|
|
# workflow when upstream changes. Hardware-agnostic — works

|
# for any platform with Modern Standby firmware (Dell, HP,

# Lenovo, LG Gram, etc.).
