I added USB-C software support just in case, but without any PD protocol support.
FUSE also added.
Debs are republished with same names.

The PD/QC protocol IC doesn’t talk to the processor. It only talks to the power adapter.
Didn’t workout for me with a fresh install of Ubuntu 20.04, error on the last command.
could you advise on the removal command.
dpkg --remove …?
Thank you.
Looking forward to it being compatible.
Updated to Linux 5.8.17.
Patches rebased against new kernel:
Are you gonna be updating the patches for 5.9?
No. It’s too much work to rebase for every series, and nothing about 5.9 is particularly earth-shattering for the Rock Pi X’s components/Silvermont.
ZSTD compression?
can this kernel support GPIOs and SPI port? where is the .config file?
.config
is in the deb, just run ar -x blahblah.deb
and then tar -xf data.tar.xz
.
Try it, I enabled everything that made sense for this board.
cat boot/config-5.8.17 | grep 'GPIO\|SPI' | grep -v '^#'
CONFIG_INLINE_SPIN_UNLOCK_IRQ=y
CONFIG_MUTEX_SPIN_ON_OWNER=y
CONFIG_RWSEM_SPIN_ON_OWNER=y
CONFIG_LOCK_SPIN_ON_OWNER=y
CONFIG_ARCH_USE_QUEUED_SPINLOCKS=y
CONFIG_QUEUED_SPINLOCKS=y
CONFIG_REGMAP_SPI=m
CONFIG_KEYBOARD_GPIO=m
CONFIG_SERIAL_MCTRL_GPIO=m
CONFIG_SPI=y
CONFIG_SPI_MASTER=y
CONFIG_SPI_PXA2XX=m
CONFIG_SPI_PXA2XX_PCI=m
CONFIG_SPI_DYNAMIC=y
CONFIG_GPIOLIB=y
CONFIG_GPIOLIB_FASTPATH_LIMIT=512
CONFIG_GPIO_ACPI=y
CONFIG_GPIOLIB_IRQCHIP=y
CONFIG_GPIO_SYSFS=y
CONFIG_SND_SPI=y
CONFIG_SND_SOC_I2C_AND_SPI=m
CONFIG_RTC_I2C_AND_SPI=y
CONFIG_INTEL_INT0002_VGPIO=m
So perhaps maybe for 5.10?
Also it seems you didn’t update the patches, as I keep getting failed builds during the patch phase…
The patches in my build tree match what are posted. It must be a problem with your build process as these apply cleanly to the 5.8.17 sources.

Found some cycles this weekend, decided to rebase everything onto 5.9(.8) this weekend and got it booted… doing some testing prior to releasing.
Andi Kleen may have stopped supporting the FLTO patches (as Clang LTO is supported instead for 5.10rc presumably?) and I don’t know how long I can keep them going as it’s very detailed kernel work.
There was a tricky little optimization that broke the LTO builds hopping from 5.8 to 5.9 that I had to figure out that would have ordinarily been a part of those patches.
Kernel 5.9.8 binary and patches posted.
New patch set lto-tjs.patch is my patches on top of Andi Kleen’s LTO patches. It was needed because they now do pointer comparison for some optimization, and the LTO was reordering the functions during the link step that broke the pointer comparison optimization.
Big sigh of relief - managed to front-port the patches to 5.10(-rc4) tonight, which turned out to be even harder than 5.9. 5.10 is designated to be an LTS kernel, so even if future version become too hard to continue to support for GCC LTO, we can ride the LTS wave out on the Rock Pi X for awhile!
Same thing, will test some and wait for 5.10 release before publishing binaries.
Fantastic! Thanks a lot!
Maybe put your patches in a Github repo?
Thanks @tjcs90 for your efforts! Does the kernel you built contain lvm / device mapper modules?
I tried to boot my fresh Debian 10 installation with it, but it failed to an “Incompatible libdevmapper 1.02.155” error, which might be because I installed my system on top of LVM.
If that’s the case would you mind including LVM / device mapper (dm) support in your next build?
Any chance you’ll make an upgrade to 5.12?
Hate to necro a thread but I dont suppose anyone still hase the .config for this kernel? The domain no longer resolves.
