sata doesnt work on tegra124-jetson-tk1 on next and master and at least since 5.2 (but 5.1 works).

It looks strange, because (on same device) , I have sata working as
appropriate, but ethernet fails with me.

It might worth to have another report.

Hello

Mine has ethernet works well. But I hit many problem with it and older kernel.
Perhaps the 5.1.21, were I am stuck, does not have it.

Anyway, the tegra of kerneci has the same SATA problem.

Maintainers, any idea on this sata issue ?

I have checked our bootlogs for v5.6-rc7 and don't see the issue with
either the tegra_defconfig or the multi_v7_defconfig. I am wondering if
this could be due a difference in the bootloader version. Currently we
are testing with a v2019.07 u-boot bootloader. Looks like the kernelci
board is using an older u-boot. Obviously it should still work, but
would be good to know if the reason why were are not seeing this is
because of the bootloader.

Another thing to check would be the pll_e clock frequency on a working
build and non-working build to see if there is a difference in the pll
frequency that is causing this.

Cheers
Jon

Hello

My uboot is 2016.01-rc4-00002-g3861d78, so a bit old.
I have a mainline uboot build for this tegra, but still didnt find a clear way to update it.
Did you have a good documentation on how to update it ?
If possible some clear uboot commands to update it via tftp.

Thanks
Regards

Not sure about TFTP, but you can find the standard flashing scripts for
various devices here:

	https://github.com/NVIDIA/tegra-uboot-flasher-scripts

Those work by uploading the image via RCM and then running the commands
to flash it.

I think those scripts will also create the images that they will flash,
so you should be able to download that image via TFTP and then flash it
using the command that the tool would normally use.

Hello

I have upgrade uboot to 2019.07 with it thanks.

But this do not change the SATA behavour:
And with today next, lots of newer warning for the clk appeared.

Hello

I have digged a bit more and with the following "patch" I have now access to sata again
diff --git a/drivers/clk/tegra/clk-pll.c b/drivers/clk/tegra/clk-pll.c
index 0b212cf2e794..b4e2020051d5 100644

        input_rate = clk_hw_get_rate(clk_hw_get_parent(hw));

This patch lead to a probed ahci, and I can see "clk_plle_tegra114_enable pll_e" in messages.

So the bad part of bff1cef5f23afbe49f5ebd766980dc612f5e9d0a is found.
As additional information, my previous kernel has CONFIG_PHY_TEGRA_XUSB=m (since firmware is on rootfs which is on sata)
but with this sata fail the same, having CONFIG_PHY_TEGRA_XUSB=y (and so xusb firmware in kernel) seems "necessary" for having SATA working.

Regards

Hello Labbe,

Looks like indeed this PLLE change should be reverted. I see that the
code disables PLLE before changing its configuration, so apparently the
enable-check shouldn't be needed.

Sounds like PLLE needs to be enabled for SATA, but ahci-tegra driver
doesn't do that.

Could you please try this change:

I'd try to enable all the clocks and voltage regulators that are enabled
by the USB driver. Also won't hurt to check the clock rate
configurations with the enabled / disabled USB, try to replicate the
working configuration.

Looking at clk_plle_tegra114_enable(), there's a bunch of configuration
going on other than just enabling the PLL_E and it's likely that whoever
set up the PLL_E first (probably some bootloader) didn't have the same
requirements as the kernel has (most notably I can imagine that hardware
control of the XUSB and SATA PLLs remains disabled in the bootloader due
to the different way that they are used.

Peter, do you have any more background on what could be going on here or
who might be initializing the PLL_E (and others) in an incompatible way?
An alternative might be to identify who configures the PLL badly and fix
the culprit. But that's a bit of a strong dependency for my taste,
especially given that currenty versions of the bootloaders are broken.
