"Based on the previous work of Arnaud Patard[1] and Yajin[2], just
finished a basic 2.6.37 support(pci, irq, reset, video) for Gdium and
pushed it into our master branch[3]"
That is great news! I have been struggling with Yajin's tree (2.6.32, I
think) which seemed to have an affinity for IO warnings and lock-ups. Also
the Mandriva-managed 2.6.29.6 sources fail to compile because they are
prepared for a different binutils patchset, besides those sources are very
old anyway. I am used to customizing the kernel for my desktop and
fileserver, so without this opportunity I felt a bit restricted - which
just will not not do for a Loongson system ;)
"The pm support(mainly "suspend to RAM") from
arch/mips/lemote/lm2f/*pm* (stl2_suspend2.patch, this may be hard too
but should be easy for basic pm support, the Hibernation should be
usable currently.)"
Actually, I have yet to experiment with hibernation / standby on the Gdium.
I feel that with Gentoo, it already boots and halts sufficiently quick
without this support. But I definitely welcome the effort, and I will
experiment with suspend-to-disk now that I know it is available.
Thank you all, Wu Zhangjin, Zhou Yajin, Zhang Le, Arnaud Patard, Philippe
Vachon and others for continuing development on the Loongson systems,
especially the non-Lemote one ;)
