Here is the latest consolidated pull request for the supported linux-yocto
kernels.
- We have a refresh of the 3.14-rt support
- bluetooh configuration changes for common-pc/qemux86
- braswell BSP features and fixes
- Introduction of the 4.1-rc1 -dev kernel (and associated perf fix).
I've built and booted these on my local machines and qemu, and
everything was sane.
The -dev kernel obviously isn't something for deployment yet, but
it builds, and forms the base for follow up config changes, features
and development work. I built and booted core-image-kernel dev with
the 4.1 changes in place.
The autobuilder showed up this for an x32 build :/.
Can one of the intel folks have a look at this ? I won't be able to get
to it until Tuesday at the earliest.
I had a look into this. The issue is that this has been applied:
http://git.yoctoproject.org/cgit.cgi/linux-yocto-3.19/commit/?h=standard/base&id=423e98721e048f6c7b925a75448f6c4ecb2b5b69
but it needs:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ce793486e23e0162a732c605189c8028e0910e86
and the ioapic driver also appears to need:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/?id=ecf5636dcd59cd5508641f995cc4c2bafedbb995
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/?id=62d1141ff34e35de496ba06491c8e854b23b3f3e
which meant I also had to add:
struct resource_win {
struct resource res; /* In master (CPU) address space */
resource_size_t offset; /* Translation offset for bridge */
};
to drivers/acpi/ioapic.c to make it compile which appears to be related to:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a49170b552423a3e85fc4f0d778c707402ee4863
which depends on a number of patches from around that time which change
acpi/resource.c:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/drivers/acpi/resource.c
(from 2015/2/3)
At this point I'm out my depth on how you want to fix this but it does
appear related to the Braswell changes.
To be clear qemux86 and qemux86-64 don't build at all with this series.
I'll see if I can just drop the Braswell parts.
I did reproduce the issue here as well, so with any luck, I can sneak
enough time to have this fixed for Monday after all.
Bruce
Cheers,
