uClinux-dist patches?

Hello

I need to check what Switchfin patches applies to the Blackfin uClinux-dist after it's downloaded in ./dl.

Are the patches limited to those in ./package/uClinux-dist/vendors/Rowetel/IP04/pre_config and ./build_ip04/blackfin-linux-dist/bfin_patch, or are there other patches elsewhere in the tree?

Thank you.

Re: uClinux-dist patches?

The patches are in package/uClinux-dist/common. Obviously the "notused" files are not used. smile The stuff in package/uClinux-dist/vendors/Rowetel is used to configure uClinux for our devices. It gets copied whole to build_ip04/blackfin-linux-dist/vendors so I guess you could call it a patch.

Re: uClinux-dist patches?

Thanks for the info. So there are actually very few patches applied to the kernel, and most of the patches done by Switchfin are for applications.

Out of curiosity, what are those "*.notused.patch" files: Patches that used to be needed in previous releases of Switchfin but are no longer necessary?

I guess so. I'm not sure why they were renamed and not just deleted. It's not like there won't be a record of them somewhere.

I guess nobody wants to spend time removing old stuff from the source tree. Thank you.

Hi Guys,

Those 'notused' we currently don't apply but there is big chance we will need them.
 
I'll do some test as soon as I can and will clean them.

Thank you.

Re: uClinux-dist patches?

Thanks for the clarification.

Incidently, I'm using "iperf" to stress-test the IP01 revision 0.5 with the standard uClinux-dist kernel, ie. without the dm9000 patch, and it seems to be OK. I guess the patch is required for revision 0.6.

Hi Gilles,

If you happen to test the patched dm9000 driver, please share the results with us.

Cheers

Ok, I'll run iperf overnight to check, and then apply the patch manually to see if it makes a difference.

Re: uClinux-dist patches?

I ran iperf on an IP01 rev 0.5 and uClinux 2010 without the patches to dm9000, and the test runs OK.

I notice that when running "iperf -r" on the client, the server stops running after a while and must be restarted. Since this issue occurs even when I run iperf from a Windows client, it's not specific to running uClinux on the Atcom.
