Kernel Support ===================== We are talking with Ubuntu kernel team about how to better sync up kernel patches between us. The initial plan is: we will have a dedicated engineer -- Chetty, Jay<[EMAIL PROTECTED]> in our team to take all of our Moblin patches and port, support and push them into Ubuntu's new branch of the Ubuntu kernel. Other Moblin kernel members will continue to commit changes to Moblin kernel with notification to Jay. And Jay may need assistance from the whole team when porting the changes to Ubuntu's kernel branch. Hope to finalize the plan during Intel/Ubuntu sprint.
File-system corruption on hard shutdown (https://bugs.launchpad.net/bugs/176178) issue got fixed after fixing the /dev/sda1 ext2 partition mounted as read-write bug. Thanks Michael Frey for his patch. PSB / SLT HW Support ==================== The broken MWAIT/local APIC timer issue got fixed after applied BIOS 66 to Crown-beach boards. Thus the kernel cmdline option nolapic_timer is not necessary any more. And when removed nolapic_timer options, the HT got enabled without 200+ interrupts per second issue. Jacob investigated many "APIC error on xx(xx)" kernel messages during booting issue (see Unclear APIC error msg reported when enable HT in CRB BIOS https://bugs.launchpad.net/bugs/180252) and found: 1. BIOS does not set DTS (Digital thermal sensor) thresholds correctly. 2. BIOS configures LAPIC thermal interrupts to be delivered via SMI. SDIO ==== Feng committed a Marvell 8688 combo-card workaround (a force 100ms delay after power-on) to Moblin kernel. Dabney Thermal patches ====================== No changes this week. USB Client Drivers ================== No changes this week.. PSB Gfx & Video Drivers ======================= Inuka found an issue where PSB Gfx will set default resolution to 1280x1024 when drivers/acpi/video module was not inserted. But still need to rootcause this issue. Inuka has been working with Bryce to try to integrate PSB Gfx Beta3 driver to Hardy. Inuka has fixed the patch applying issue, but the built binary package does not function correctly. Inuka will continue to support on this issue. Power and Performance Testing/Optimization ========================================== Jay completed a complete ACPI verification for Crown-beach board and fixed the issue where procfs did not get correct temperature. Jay also fired a bug "Closing the virtual lid does not turn the display off" (https://bugs.launchpad.net/moblin-kernel/+bug/183013) and need to rootcause it. Jay also successfully built the midbrowser with Intel compiler (ICC) and did a performance comparison between the GCC built midbrowser and found a very good increase in performance (25%+ for browser launching, and 20%+ page loading from QA team) Grub fast boot/resume ================ Martin is working on fixing the issue where fast resume gets hung when HT is enabled. Thanks, Alek
