Description Barnabás Virágh 2020-02-27 14:36:36 UTC
Created attachment 616188 [details]
sgiseeq driver patch

Netbooting the kernel sys-kernel/mips-sources-4.19.79::gentoo on Indigo2 Impact 10000 machine shows sgiseeq network driver
1.) warning with stack trace from include/linux/dma-mapping.h:516 (in dma_alloc_attrs())
called from drivers/net/ethernet/seeq/sgiseeq.c:742 (in sgiseeq_probe())
2.) The exiting with "Sgiseeq: Page alloc failed, aborting.", -ENOMEM

With the attached patch, the ethernet driver initializes, and works. Can mount NFS root filesystem, and already running for several hours (13+) building a kernel. Though, I don't know if it would interfere with other systems.

Comment 2 Joshua Kinard gentoo-dev 2020-02-28 03:48:40 UTC
This sounds like something that really ought to go upstream.  If you haven't already, I encourage you to join the linux-mips kernel mailing list here:

And you can learn more about submitting patches to the Linux Kernel here:

Although this is a MIPS-specific driver, it touches the networking subsystem, so you'll need to involve the Linux networking subsystem maintainers.  They maintain a FAQ here:

An actual patch submission for this fix will need to go upstream via the netdev mailing list (which you don't have to join to actually submit to), with the linux-mips ML CC'ed.
Comment 3 Barnabás Virágh 2020-02-28 10:24:25 UTC
But for that, first I will have to try it also on vanilla kernel, haven't I?
Thanks for the directions anyway. Can you/someone try out the scenario/dirty patch of mine, to confirm that it not only works for me? Probably on a different machine which also uses the same net driver?
