systemd: re-enable timedated (was -Dtimedated=false). Drop the
post-install safe_remove that nuked /usr/bin/timedatectl so users
can finally run timedatectl set-timezone from the shell. Two
upstream-equivalent patches accompany the build: 0600 redirects
the timedated write target to /var/run/localtime (writable on our
read-only rootfs), 0601 makes the timezone reader follow indirect
symlinks (matches the /etc -> /storage layout).
udevil: pull the cleaned udevil.conf (UFS gate moved from
allowed_devices to forbidden_devices, /dev/sd* whitelisted as
removable). The udev rule now bails on anything that is not
usb-storage. Internal mmc devices were never matched by the prior
KERNEL=="sd*|sr*" filter anyway, but this makes the intent
explicit and stops misclassified eSATA-like devices.
input_sense: grep -line-buffered before the parse loop so only
EV_KEY / EV_SW / error-reading lines reach the case statement.
evtest output is mostly EV_ABS noise we threw away anyway; this
cuts the CPU spent on the dispatch hot path on every controller.

retroarch: bump to commit bdba046f (v1.22.2 + fixes) and rebase the
two local patches (0010-paths, 0011-cheevos-sounds) so they apply
cleanly against the new tree.
setsettings.sh: configure_hotkeys now detects the InputPlumber-emulated
DualSense pad first, then falls back to js0 / joypad. Without this,
retroarch took the raw event device and the hotkey binding never
matched what InputPlumber actually exposed to userspace.
drastic-sa: pull the new libdrastouch (sharp-shimmerless + quilez
pixel shaders, SDL2 hook) and the matching start_drastic.sh, which
now reads the shader setting and exports DSHOOK_SHADER. Drops the
dead S922X libmali block we never executed on RK3326.
hypseus-singe: rewrite of start_hypseus.sh fixes broken controls
(autoconfig.cfg lookup was matching too loosely) and adds the
set_kill on exit so the quit hotkey actually terminates the
emulator instead of leaving it parented to ES.
ppsspp-sa: add 005-hide-unsupported-ui-items.patch to drop the
"www.ppsspp.org" link and the "Buy PPSSPP Gold" button from the
main screen. Handheld UX cleanup, no behavioral change.

mali-bifrost (RK3326): replace patch 003 with the clean RK3576-style
version. Drops the dead BSP-style probe-defer dance, balances the
regulator refcount during probe (mirrors the clock prepare/enable),
and removes the regulator_is_enabled guard that was silently skipping
the disable on suspend. Frees the kernel log of the "missed warnings"
sunshineinabox flagged.
iwd (network): ControlPortOverNL80211=true so 802.1X EAPOL frames go
through nl80211 instead of the legacy raw socket. Some clones with
modern wifi firmware fail association otherwise.
linux 6.12-LTS: add 0020-usb-gadget-u_ether-guard-NULL-gadget upstream
fix. Without it, querying ethtool on the surviving NCM interface
during gadget detach dereferences a NULL dev->gadget pointer and
panics. Affects anyone who flips USB gadget mode at runtime.

The ROCKNIX fork includes all 3 patches we maintained separately:
- 000-dark-theme.patch
- 001-default-paths.patch
- 002-build-fix.patch
Switching to the fork removes the maintenance burden of patch rebasing.
Adapted from ROCKNIX dd10d27a84 to projects/ArchR/ path.
DEBUG_FS provides instrumentation needed by TODO items 1 and 6:
- /sys/kernel/debug/dri/*/name — GPU performance counters
- /sys/kernel/debug/cma/* — per-region CMA page accounting
- /sys/kernel/debug/block/* — I/O scheduler stats (BLK_DEBUG_FS)
- Detailed thermal zone introspection
Trade-off acknowledged: small runtime overhead from debugfs mount,
but the instrumentation granularity is essential while we're actively
benchmarking and tuning. Switch to DEBUG_FS=n or DISALLOW_MOUNT
for release-final builds once FASE 1-2 benchmarks are complete.

Flycast-SA:
- Restore -Ofast sed (was incorrectly replaced with CMAKE_BUILD_TYPE=Release)
- -Ofast = -O3 + -ffast-math is INTENTIONAL for Flycast: the Dreamcast SH4
FPU doesn't use strict IEEE 754, and the hardware itself flushes denormals
- Validated by JELOS/AmberELEC/ROCKNIX upstream for years without issues
- On weak Cortex-A35, the extra optimization from -ffast-math is meaningful
Sysctl:
- vm.dirty_writeback_centisecs: 500→1500 (match ROCKNIX, reduce I/O wakeups
during gaming — read-heavy workload needs fewer writeback checks)
- vm.vfs_cache_pressure: 50→100 (restore kernel default — during gameplay
the same few files are reread (ROM, save, shader cache), so a large
inode/dentry cache provides no benefit on 1GB RAM. 50 is a desktop tuning
that favors metadata cache for build/compile workloads, not gaming.
Note: 200+ is what aggressively reclaims metadata; 100 is the neutral
kernel default, not an override.)

FRAME_POINTER:
- ARM64 Kconfig unconditionally selects FRAME_POINTER (arch/arm64/Kconfig:136)
- Cannot be disabled regardless of defconfig value
- Overhead <1-2% on ARM64 (x29 designated as FP by ABI, STP saves FP+LR
in single store queue slot)
- Restored to y to match kernel reality
ZRAM compression lzo-rle (reverted from zstd):
- zstd is 3-4x slower than lzo-rle on in-order Cortex-A35
- Estimated: lzo-rle ~350 MB/s vs zstd ~100 MB/s compress on A35
- Each 4KB page swap: 11us (lzo-rle) vs 40us (zstd)
- Under memory pressure during gaming, zstd causes frame stutters
- ROCKNIX deliberately uses lzo-rle on ALL in-order cores (A35/A53/A55)
and only enables zstd on out-of-order big cores (A73/A76)
- The extra ~500MB virtual capacity from zstd's ratio is not worth the
latency penalty for latency-sensitive gaming workloads

Kernel:
- BRIDGE_NETFILTER=n (was still =m after BRIDGE was disabled)
- BLK_DEBUG_FS=n (depends on DEBUG_FS which is off, explicit disable)
Flycast:
- Replace sed -Ofast hack with proper CMAKE_BUILD_TYPE=Release
(CMake Release mode applies -O3 with proper LTO support)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- ZRAM compression: lzo-rle → zstd (better 1:3 ratio vs 1:2.5, saves
~50MB more RAM on 512MB ZRAM at cost of slightly more CPU)
- Add zswap.enabled=0 to kernel cmdline (zswap intercepts before ZRAM,
preventing efficient compressed swap)
