+  It's patched to register its notifier without a port name when the board
+  has one CEC port: amdgpu registers its HDMI notifier nameless, and the
+  kernel only pairs that with a named lookup ("Port C") when the CEC driver
+  registered first, which never happens since amdgpu loads from the

+- Power-off fix (`poweroff`, `lib/fremont-poweroff.sh`, a default sub-option
+  of `machine`): recent kernels (7.2 and the 6.x/7.0/7.1 updates with the
+  backport) keep the firmware's S4/S5 wake bit on GPIO
+  pin 18, so the Steam Machine boots again right after powering off
+  (Valve's kernel clears it at probe, not for upstream). The DKMS module
+  `steamify-fremont-poweroff` (`patches/steamify-fremont-poweroff.c`) clears
+  it in a power-off-prepare handler, built for each kernel. It made the kernel pin
+  unnecessary: `kpin` is only available while on (`kpin_available`), and
+  `detect_components` unticks it, so a normal run removes an existing pin.
+  `hdmi` (it needed the pin) is retired the same way: `hdmi_status` is on
+  while anything of it is left (saved displays, hotplug unit, EDID files,
+  old kernel parameter), `hdmi_available` only then, it's always unticked,
+  and `hdmi_disable` removes all of it. CachyOS's
+  `linux-cachyos` is clang-built, `-bore` GCC-built: let DKMS pick the
+  compiler, never pass `LLVM=1`. Test shutdown on the real machine for every

+- `3c8ca65` **fix(ui): Never write the sudo password to a file; Update label on the progress screen**
+  - The app gave `sudo` the password through a short-lived file; the helper
+    now reads it from a named pipe the app feeds from memory each time sudo
+    asks. The progress screen showed "undefined" for an update.
+- `11a91ef` **feat: Update badge on components that get a newer version**
+  - The menu (terminal and app) shows "(update)" / an Update badge after
+    the name of a component a normal run will update.
+- `163f790` **feat: Feature versions are Steamify versions; Steam Machine support is 2.2.0**
+  - Each component records the Steamify version of what it set up; when a
+    release changes a component, installs with an older version are ticked
+    and updated by a normal run ("update" in the plan and the app's
+    review). A setup from before counts as 2.1.0, so Steam Machine support
+    (2.2.0) is updated on machines set up with 2.1.0. New default
+    sub-options (like the power-off fix) are ticked where their parent is on.
+- `e121b06` **fix: Remove whatever is left of HDMI refresh boost, pin or no pin**
+  - HDMI refresh boost needed the pinned kernel and is retired (newer
+    kernels do HDMI 2.1 themselves): whatever is left of it (saved
+    displays, also ones not connected, its hotplug script, the old kernel
+    parameter) is unticked and removed by the next run.
+- `19ca966` **docs: Drop the kernel pin and HDMI refresh boost descriptions**
+- `56fb908` **docs: Power-off fix texts cover every affected kernel, not just 7.2**
+- `6df19eb` **feat: Power-off fix as its own sub-option, drop the kernel pin, feature versions**
+  - The power-off fix is a sub-option of Steam Machine support, ticked
+    along with it (opt-out). The kernel pin is no longer offered: an
+    existing pin is shown unticked, so the next run removes it and brings
+    back CachyOS's current kernel.
+- `7694c97` **feat: Power-off fix for the Steam Machine; the kernel pin is optional**
+  - With recent kernels (newer 6.x, 7.0 and 7.1 updates, 7.2 and probably
+    later ones) the Steam Machine started again right after shutting down:
+    they keep the wake bit the firmware sets on GPIO pin 18, which Valve's
+    own kernel clears in a patch that won't reach CachyOS. A small module,
+    built with DKMS for each installed kernel, clears it right before
+    power-off. Tested with CachyOS 7.2.8: stays off, and without the module
+    it rebooted.
+  - Module sources and patches live in `patches/` instead of inside the
+    shell code; the single-file build and the app package include them. The
+    Steam Machine CEC driver change is now
+    `patches/cros-ec-cec-single-port.patch`.
+
+## 2.1.0 - 2026-09-26
+
+- **feat(ui): Manage button for HDMI refresh boost**
+  - The item's switch is a button: Set up… while no display is saved,
+    Manage after that. Manage lists the saved displays (connected or not),
+    removes one with its Remove button, and sets up the connected display
+    when it has no saved rates yet.
+- **4cc87aa feat: HDMI refresh boost per display, with a Saved displays screen**
+- **36d0a9d feat: HDMI refresh boost only for the display it was set up for**
+  - The EDID override was on the kernel command line, so any display on that
+    HDMI port got the first display's timings. Rates are now saved per
+    display and loaded at boot and at every hotplug for the display that's
+    connected (its ID read over DDC); a display without saved rates, or
+    unplugging, puts the port back on the display's own EDID. No initramfs
+    or boot loader change any more. An existing setup is moved over when
+    re-applied (`a`).
+  - The item shows on only while the connected display is boosted, so a new
+    display can be set up by ticking it; unticking removes only that one.
+
+## 2.0.3 - 2026-09-26
+
+- **fix: HDMI-CEC on the Steam Machine**
+  - Mainline's `cros_ec_cec` driver doesn't know the Steam Machine, so there
+    was no `/dev/cec0`. HDMI-CEC now builds Valve's version of the driver
+    with DKMS (`steamify-cros-ec-cec`) for every installed kernel, with a fix
+    so it finds amdgpu's HDMI port even though amdgpu loads first. An
+    existing HDMI-CEC install is ticked in the menu to add it.

+  - States that the project isn't affiliated with Valve or CachyOS, and that

+  - "Steamify CachyOS" on the desktop and in the launcher starts the newest

-## Kernel pin (Steam Machine)
+## Power-off fix (Steam Machine)

-With CachyOS kernels newer than 7.1.6 a Steam Machine reboots instead of
-shutting down. The **Pin the kernel** sub-option (ticked along with Steam
-Machine support) installs `linux-cachyos` and `linux-cachyos-headers`
-7.1.6-1 and adds them to `IgnorePkg` in `/etc/pacman.conf`, so updates skip
-them. DKMS builds the LED driver for it; restart to boot it.
+With recent kernels a Steam Machine starts again right after powering off:
+the newer 6.x, 7.0 and 7.1 updates and 7.2 (and probably every kernel after
+it). Linux stopped clearing the S4/S5 wake bits at probe
+(`pinctrl-amd: Don't clear S4 wake bits at probe`, in 7.2 and backported to
+stable kernels), and the firmware leaves
+that bit set on GPIO pin 18 (`_SB.PCI0.GPP6`). Valve's own kernel
+(`linux-neptune-72`) clears it at probe on Fremont, in a patch marked not
+for upstream ("until the firmware is fixed"), so CachyOS and mainline won't
+get it.

-The packages (and their signatures, which pacman checks) are kept in
-`/var/cache/steamify/kernel`, so re-applying needs no download. Missing
-files are taken from pacman's cache, else downloaded from this repo's
-`kernel-7.1.6-1` release, then `archive.cachyos.org`, then
-`mirror.cachyos.org` (which only has the current kernel). Every file must
-match the SHA-256 in the script and have a valid CachyOS signature; a bad
-one is deleted, so the next run downloads it again. Set `PINNED_KERNEL_URL`
-to a directory URL with the files to try another source first, or drop them
-into the kernel directory yourself.
+The **Power-off fix** sub-option of Steam Machine support (ticked along with
+it, can be unticked) builds a small module with DKMS for every installed
+kernel, `steamify-fremont-poweroff` (source in
+[`patches/steamify-fremont-poweroff.c`](patches/steamify-fremont-poweroff.c)).
+It only loads on Fremont (DMI board name) and touches one register: right
+before power-off (a `SYS_OFF_MODE_POWER_OFF_PREPARE` handler, after the
+drivers have shut down) it clears that pin's S4/S5 wake bit. On a kernel
+that already clears it, it does nothing. It logs the pin's state at load:
+`dmesg | grep 'GPIO 18'`; `/sys/kernel/debug/gpio` shows the S4/S5 column.
+Tested on a Steam Machine with `linux-cachyos-bore` 7.2.8: it stayed off
+three times in a row, and rebooted right away with the module unloaded.

-Unticking it removes the pin and runs `sudo pacman -Syu`, which brings the
-kernel back to CachyOS's current version; the files stay for next time.
+Where Steam Machine support was set up before 2.2.0, the menu ticks the
+power-off fix as a new default sub-option (see feature versions below), so a
+normal run adds it.

-## HDMI refresh boost (Steam Machine)
+## Feature versions (updates)

-With the pinned kernel (7.1.6), HDMI displays often stay at 60 Hz. Two
-reasons:
+Each component has a feature version (`FEATURE_VERSION` in `lib/menu.sh`):
+the Steamify version in which what it sets up last changed (2.1.0 for
+everything that hasn't changed since). After a component is turned on
+successfully, that version is recorded in `~/.local/state/cachyos-gamescope-boot/features.state`
+(turning it off records `off`). Whether a component is on is always checked
+on the system itself; the version only decides about updates:

- Monitors list their fast modes in an extra EDID block, announced by the
-  HDMI Forum EEODB data block. 7.1.6 only reads the first extension block,
-  so it never sees them. Newer kernels do.
- Their fastest modes need HDMI 2.1 (FRL). 7.1.6's amdgpu only does HDMI
-  2.0 (TMDS, at most 600 MHz), but a mode with the display's own shortest
-  blanking at a slightly lower rate often fits.
+- **On, recorded version older** than the current one: ticked and
+  re-applied by a normal run; the plan (and the app's review) says
+  "update". A setup from before versions were recorded counts as 2.1.0,
+  so on a machine set up with 2.1.0, Steam Machine support (2.2.0) is
+  updated.
+- **A new default sub-option** (not in `NO_PRESELECT`) whose parent is on
+  and that was never turned on or off: ticked, so a normal run adds it.
+  Turning it off once records `off`, so it isn't ticked again.

-The menu item (only on a Steam Machine with the pinned kernel, never
-ticked by default, run from the desktop in Konsole):
-
-1. Takes the desktop resolution from KDE (`kscreen-doctor -j`) and reads the
-   display's complete EDID over DDC (`i2ctransfer`, segment pointer 0x30).
-   A live EDID left by an earlier test is cleared first.
-2. Calculates the highest rate that fits: the display's TMDS limit (HDMI
-   Forum VSDB, capped at amdgpu's 600 MHz), its shortest blanking at that
-   resolution and its maximum refresh (range limits, VRR maximum). Steps:
-   that rate rounded down to ten, and the hundred below it as a safe option.
-   Rates the display already lists, or that aren't faster than what works
-   now, are left out.
-3. Builds the EDID: all of the display's blocks, the block count and EEODB
-   fixed, plus a DisplayID block with the steps.
-4. Loads it live (debugfs `edid_override`, `trigger_hotplug`) and switches
-   to each step, lowest first. Each one needs a "y" within 15 s
-   (`WIZARD_HDMI_CONFIRM_SECONDS` for tests); anything else switches back
-   and stops.
-5. Makes it permanent with only the confirmed steps:
-   `/usr/lib/firmware/edid/steamify-<connector>.bin`, in the initramfs via
-   `/etc/mkinitcpio.conf.d/90-steamify-edid.conf` (amdgpu loads from there),
-   and `drm.edid_firmware=<connector>:edid/steamify-<connector>.bin` on the
-   kernel command line: `/etc/default/limine` (`limine-mkinitcpio`),
-   `/etc/sdboot-manage.conf` or `/etc/default/grub`.
-
-The display's manufacturer, model and serial are stored; re-applying with
-another display connected tests that one instead. Turning it off removes
-the files and the parameter and rebuilds. Untick it before removing the
-kernel pin: newer kernels read the EDID themselves and can do HDMI 2.1.
+Set a component's entry to the new `VERSION` whenever what its

theupriser	6df19eba3e	feat: Power-off fix as its own sub-option, drop the kernel pin, feature versions The power-off fix becomes an opt-out sub-option of Steam Machine support. The kernel pin is no longer offered: an existing pin (and HDMI refresh boost, which needs it) is unticked so a normal run removes it. Components record a feature version on each successful run; installs with an older version are ticked and updated, and new default sub-options are ticked where their parent is on.	2026-09-27 12:20:56 +02:00
theupriser	7694c97d68	feat: Power-off fix for the Steam Machine; the kernel pin is optional Kernels >= 7.2 keep the firmware's S4/S5 wake bit on GPIO pin 18, so the Steam Machine starts again right after powering off. Steam Machine support now builds a DKMS module (patches/steamify-fremont-poweroff.c) that clears it before power-off, for every kernel. The kernel pin is no longer ticked by default. Module sources and patches move to patches/, embedded by the single-file build.	2026-09-27 12:13:23 +02:00

theupriser	929ecfb349	feat(ui): Manage button for HDMI refresh boost The item's switch becomes a Set up / Manage button. Manage lists the saved displays, removes one with its Remove button, and sets up the connected display when it has no saved rates.	2026-09-26 16:48:21 +02:00
theupriser	4cc87aaea6	feat: HDMI refresh boost per display, with a Saved displays screen Rates are saved per display (EDID ID) and loaded by the hotplug script for whichever display is connected. The item is on only while the connected display is boosted; unticking removes just that one. The app lists the saved displays and removes any of them (hdmi-forget).	2026-09-26 16:13:45 +02:00
theupriser	36d0a9d780	feat: HDMI refresh boost only for the display it was set up for The EDID override moves off the kernel command line to a hotplug script (boot unit + udev rule) that loads it only while the display it was tested on is connected, identified over DDC; other displays get their own EDID.	2026-09-26 16:04:02 +02:00

theupriser	2b3f1de75a	feat: The Steamify shortcut opens the app Steamify CachyOS on the desktop and in the launcher starts the newest app (in Konsole the first time, while PySide6 still has to be installed); the terminal menu is Steamify Terminal in the launcher. A shortcut from before 2.0.1 is ticked in the menu, so a normal run replaces it. steamify-app.sh leaves the shortcut's launcher entry (same id) alone.	2026-09-25 21:32:24 +02:00
