Hi Bruce,
Would you please help remove the obsolete branch standard/xlnx-soc in
linux-yocto-dev
and apply these patches for v5.10 as below to the new branch
standard/xlnx-soc?
There are 1451 patches in this pull request.
Among them, 1443 patches are picked from
https://github.com/Xilinx/linux-xlnx.git xlnx_rebase_v5.4 (tag
xlnx_rebase_v5.4_2020.2).
and some of them are modified to adapt to the v5.10. And there are 4
new patches.
I took at look at your branch and there are some interesting things.
First of all thanks for your work.
Do you use any script of it because I see you keep references to origin
sha1 which is quite nice?
yes, the script is as below:
---
#!/bin/sh
add_sdk_commit ()
{
for each in `ls *.patch`; do title=`grep -m 1 -n "From " $each`;
echo $title
num=`grep -m 1 -n ^$ $each | awk -F : '{print$1}'`;
commit=`echo $title | cut -c 7-47`;
echo $commit
echo $num
sed "$num a\https://github.com/Xilinx/linux-xlnx.git
xlnx_rebase_v5.4\n" -i $each;
sed "$num a\commit $commit from" -i $each;
done
}
add_sdk_commit
---
Then obviously we need to switch to psgtr mainline driver and add
missing features because that's the only way to go in long run. I tested
yesterday sata and it worked. I expect DP should be also fine and others
needs to be checked. Yesterday I have sent email to Laurent to check
some details about it.
The DP driver can't work in mainline v5.9 and v5.10 now. I tried to make
it work
but failed. I modified the dts (xilinx_dpsub.patch in attachment) to
make the DP driver get through
the initialization but the DP monitor has no signal. I don't know if
this is a DP issue or psgtr phy issue.
So for v5.10 yocto kernel, I gave up using mainline DP driver and
reverted DP/psgtr/dpdma mainline
drivers to use SDK drivers instead.
If the DP driver can work in the near future, I would like switch to
mainline DP/psgtr/dpdma driver.
Xilinx is going to prepare v5.10 rebase tree with fixing these problems.
Is there any developing version based on v5.10 at Xilinx now? Wish for
some reference.
I am just starting to work on that. And checking these stuff one by one
to address them properly ahead.
Got it. Thanks for the info.
Thanks,
Quanyang
Thanks,
Michal
