20120327 Meeting Agenda


ARM Status

P/omap4: since a critical bug (lp963512 – “Latest kernel updates broke video on omap4″) was affecting 3.2.0-1410.13, for beta2 the kernel was reverted to a previous working version (3.2.0-1409.12). AFAIK the regression came with latest rebase on master (3.2.1[0-2]) while the TI BSP was unchanged – so it’s either a bad interaction between upstream/TI BSP or it’s a brand new bug we got from upstream.
lp956693 (“Broken perf with Ubuntu-3.2.0-1408.11 at Pandaboard”): one of the patch from Linaro tried to enable perf hw support but it wasn’t ready for prime, reverting it gave us perf ba
ck in a working shape.
lp666267(“Cross compiled headers package breaks DKMS compilation”): two patches that address this issue were resurrected from O and ported to P, scripts/* are correctly cross compiled no
w.

following the release on Thurs. Note that Kernel Freeze is next Thurs
Apr 5. I intend to upload our final kernel no later than Tues Apr 3.
