Debugging DT on IGEP board

by Deepak Saxena

Hi all, We're trying to close out on a few 11.05 items and two that stand out are completing DT support on IGEP and u8500 boards. The code is in place in the linaro-2.6.38 kernel but we need someone with HW to debug why it's not working. I'm working on sorting out the u8500 testing, but does anyone in the kernel team or landing team have the HW on hand and able to coordinate with Grant on debugging on the IGEP? ~Deepak

Use of GCC __attribute__(("FIQ")) in Linux kernel?

by Chung-Lin Tang

Hi kernel folks, there's an upstream GCC PR about banked registers not being properly utilized in FIQ routines, specified by GCC attibutes, see here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48429 I was just wondering, is this GCC __attribute__(("FIQ")) feature used in the Linux kernel as well, or are the entry paths in Linux already done in assembler? Thanks, Chung-Lin

*** Kernel meetings schedule changes ***

by Deepak Saxena

Hi all, I have a couple of schedule changes for tomorrow to announce: 1. The kernel wg + landing team discussion has been moved from 5pm to 2pm in the TAS room. Scott B. synced up with me and Nicolas is leaving at 4pm and it is critical that he be involved in this discussion hence the move. 2. The kernel working group team meeting that was scheduled for 2pm tomorrow obviously not happening at the same time and will be reschedule for a different time and send out and update. Thanks, ~Deepak
