06:16.03CapnKernelThe files in target/device/Atmel/*/*_defconfig are very old, haven't been updated in a while.  How do they get updated?  Who can do it?  And how?
06:36.02HcEI could always commit the files from my branch
06:36.16HcEthe ngw100-extended is a bit unmaintained IMHO
06:36.23HcEperhaps remove it?

07:30.47CapnKernelThe ngw100-extended is the newest one!!!
07:30.47CapnKernel<PROTECTED>
07:31.35CapnKernelIt seems the defconfig files are mostly atmel chips.
07:31.43CapnKerneland will have a lot of similarity.
07:32.49CapnKernelwonders if it would be possible to generate the defconfigs from some kind of master file, maybe with some sort of preprocessing. Then that one master file can be kept up to date.
07:33.32CapnKernelAlso, what's in the master file can be checked against what you get out of the Config.in system, to alert to any needed changes.  For example, a variable which is not set in the defconfig.
07:35.19CapnKernelmake defconfig gives the default output of the Config.in rules, but I can't see a way to override the architecture to get a default dump.
07:35.32CapnKerneldefconfig gives an x86 dump
07:39.15CapnKernelWould like to get an ARM dump...

19:50.49like2wiselandley : hi
19:53.21landleylike2wise: hello.
20:07.15landleySo what is avr32 use for, anyway?
20:13.17prpplaguelandley: avr32 is atmel's attempt at the 32bit SoC market
20:13.56prpplaguelandley: right now its mostly used in industrial stuff, and there is a inexpensive dev board, the ngw100, that has networking
20:15.03landleyHas anybody made noises about getting qemu to fake it?
20:17.14prpplaguenothing i've heard about
20:53.29HcEqemu support is on the list of TODOs
20:53.45HcEit is needed for submitting toolchain stuff upstream
20:56.30prpplaguepoints to HcE he is the maintainer of the avr32 , iirc
20:57.45prpplaguelandley: HcE knows more about the avr32 stuff
21:02.45landleywaves at HcE.
21:03.06landleyI have a project that aims to cross compile a self-hosting development environment for every target qemu supports.
21:03.14landleyI'm currently getting m68k working, and then I need to go unbreak powerpc.
21:03.21landley(Worked on the 2.6.25 kernel, doesn't now.  Sigh.)
21:03.58landleyIt turns out the internal compiler error in m68k goes away if you yank "-Os", so that's unblocked.
21:04.00HcEnot done that much with qemu except use it
21:04.07landleyI'm mostly a user of qemu myself.
21:04.14landleyA couple of small patches, but nothing deep.
21:04.22HcEwell, you should compile the kernel with -O2
21:04.31HcEsome GCC's does it wrong with -Os
21:05.02landleyThat said, I subscribed to the device tree mailing list with the intention of learning enough about device trees in hope of teaching qemu to parse a device tree to synthesize the corresponding board layout.
21:05.35landleyThe linux kernel is using device trees for several architectures now, so it would be nice if qemu could read those data files to provide the same hardware interface on the other end.
21:05.55landleyHcE: the internal compiler error was building uClibc, which provides -Os by default unless you patch it not to.

21:17.14HcEah, oki
21:17.18HcEfix your compiler then ;)
21:17.48HcEwe plan to add device tree support to AVR32 soon™
21:28.23landleyI might upgrade to gcc 4.3, depends how long it takes me to get over my aversion to gplv3.
21:28.31landley4.1 I found a workaround for already.
21:29.32landleyAnd 4.2.2 has the exact same bug as 4.1.2.
