Porting Jetson 3.1 for TX2 to upstream kernel 4.14-rc4

Hi Forum,

Jetson 3.1 is based on Linux kernel 4.4.38 version.

My requirement is to run Linux kernel 4.14-rc4 kernel on Jetson TX2 (4 A-57 cores + 2 Denver cores).

Please let me know, if such a pack based on 4.14-rc4 is already available for TX2 or the recommended procedure (if any) to port TX2 Jetpack to 4.14-rc4 ?

Thanks,
-Aleem

Hi aleem_chisti,

We haven’t planned to migrate Jetson TX2 kernel to 4.14-rc4 yet, hope other developers could share their experience.

Thanks

Hi aleem_chisti.

I’ve done experiments on kernel 4.13.10.

Compile all right. The boot kernel that I have on the ssd disk is an error - I can not find the disk on / dev / sda1.

As it seems, the vanilla kernel does not have support for the sata interface - jetson TX2.
The kernel configuration is missing:
config ARCH_TEGRA_HAS_SATA
bool

config SATA_AHCI_TEGRA
tristate “TEGRA AHCI SATA support”
select ARCH_TEGRA_HAS_SATA
help
This option allows support for TEGRA AHCI Serial ATA.

If unsure, say N.

It is sad. I’m trying to get the patch for this problem. So far without a positive result.

Best regards
