enable silead driver modules in kernel config

I pushed changes to your repo to rename the commit. Now you need to show testing/evidence of the changes working.

in libreelec build overlay and produced img is missing file for systemd sensors for rotation https://github.com/systemd/systemd/blob/main/hwdb.d/60-sensor.hwdb , in this file is adaptation from various sensors in devices to proper screen rotation

[chewitt]

I pushed a commit with a minimal version of the file to our systemd package. Please make the same change to your own LE image build and validate that it works?

[stpf99]

sorry files exists and "Bush tablet" is listed in /usr/lib/udev/hwdb.d/60-sensor.hwdb :
cat /etc/udev/hwdb.d/README
Hardware Database Files

The hwdb files are read from the files located in the system hwdb directory
/usr/lib/udev/hwdb.d and the user runtime directory /storage/.config/hwdb.d
All hwdb files are collectively sorted and processed in lexical order, regardless of
the directories in which they live. However, files with identical filenames
replace each other. /usr/lib/udev/hwdb.d/* takes precedence over /storage/.config/hwdb.d/*

[chewitt]

However, files with identical filenames replace each other. /usr/lib/udev/hwdb.d/* takes precedence over /storage/.config/hwdb.d/*

The reverse is true, the files in /storage/.config/hwdb.d/* override the embedded location. I'll drop the systemd change.

firmware loaded but this init error is in kernel log

[chewitt]

I've no idea about the hardware, sorry. I'm blocking the PR until you figure out what's needed (to prevent accidental merge).

this was succesed by corrupted fw file ,i replaced fw file and touchscreen works , and pointing is accurate in estouchy and estuary in portrait mode, but rotation not work and it is probably because kodi is always in fullscreen, how to resolve this, maybe somewhere is conf for screen orientation..

edit: i will try switch from GBM to Xorg my build

input for touchscreen is initiated:
LibreELEC:~ # dmesg |grep silead

this two patches also may in X11 / legacy build producing some breaks for kodi screen rotation (https://github.com/LibreELEC/LibreELEC.tv/tree/master/projects/Generic/devices/x11/patches/kodi)

this acpi patch may block if applied obtaining some values for systemd hwdb mechanism from ACPI tables (https://github.com/LibreELEC/LibreELEC.tv/blob/c1cab83d883d18e6bf110367693b85ab91fb4038/projects/Generic/devices/x11/patches/linux/linux-revert-acpi-bus-get-device-5-18.patch )

this fbdev patch if applied may break kodi windowed mode in x11 (https://github.com/LibreELEC/LibreELEC.tv/blob/c1cab83d883d18e6bf110367693b85ab91fb4038/projects/Generic/devices/x11/patches/linux/linux-revert-fbdev--Make-registered-fb---private-to-fbmem-6-1.patch),

i think in gbm images proper static screen orientation /no dynamic rotation could be set by for example
video=DSI-1:800x1280@60,rotate=90(/180/270),panel_orintation=left_side_up (/right_side_up/upside_down/normal)
in arguments in boot cmd line

/can't on my dev test this because i have "i915 0000:00:02.0: [drm] ERROR [CONNECTOR:114:DSI-1] Failed to get the SoC PWM chip"

for fix that some kernel modules needs be included
https://cateee.net/lkddb/web-lkddb/I2C_DESIGNWARE_PCI.html =y/m
https://cateee.net/lkddb/web-lkddb/INTEL_SOC_PMIC.html =m/y
https://cateee.net/lkddb/web-lkddb/PWM_CRC.html =m/y
... related cherry trail PWM = m

also drm_i915 as module must be selected /this resulting also more stable wifi connecting
"
BYT/CHT: pwm vs i915 driver initialization order when i915 is builtin

To reflect that:

This is a generic BYT/CHT issue, not Surface 3 specific

This only is a problem when the i915 driver is builtin"
https://gitlab.freedesktop.org/drm/intel/-/issues/26

in wayland in may img currently autostart kodi is broken somwhere

for gbm Generic build i have question how to set proper screen rotation, if gbm is trought fb (framebufer) where to setup rotation ?

https://www.x.org/archive/X11R6.8.0/doc/fbdev.4.html

"Option "Rotate" "string"
Enable rotation of the display. The supported values are "CW" (clockwise, 90 degrees), "UD" (upside down, 180 degrees) and "CCW" (counter clockwise, 270 degrees). Implies use of the shadow framebuffer layer. Default: off. "

this my grub cmd boot entry , but in kodi gui i have reversed resolution :800x1280

`LibreELEC2:~ # cat /flash/EFI/BOOT/grub.cfg
set timeout="0"
set default="LibreELEC"

menuentry "LibreELEC" {
search --set -f /KERNEL
linux /KERNEL boot=UUID=6C30-C3D6 disk=UUID=a1c24cd1-cc24-40db-a02c-f6f48f11bc09 gfxmode=1280x800x60 gfxpayload_linux=keep video=DSI-1:1280x800M@60,rotate=90 quiet
}
`
i prepared patch / no tested yet /later i report if gbm img starting in landscape mode

Bush_windows_tablet_drm_panel_orientation_quirks.patch
https://gist.github.com/stpf99/d2e403cd38c68a1eb8daeced32b84723

above patch also in 2nd version for "rightside_up" nothing changes in libreelec test build / on other linux systems kerenels not tested

time to produce wayland test build
