2.6.24 Kernel Support ===================== Alek continues to port the patches from 2.6.22 to 2.6.24. He is using/referencing the work previously done by Amit.
PSB / SLT HW Support ==================== Jacob still owes me a patch to work around the MWAIT/local APIC timer issue. We decided to go with the plan to mark the MWAIT instruction broken in the kernel taking out the CPU_FEATURE_MWAIT after cpuid is read for the effected processor. SDIO ==== Feng has released a kernel patch on moblin.org containing Marvell's GPL release of the 8688 WLAN + BT drivers. In the process we've removed the older & outdated MSS SDIO kernel patch from moblin.org. Pierre Ossman's SDIO stack is the only choice for SDIO support on moblin. Dabney Thermal patches ====================== No changes this week. USB Client Drivers ================== Alek continues to add support for the USB Client solution that was described previously. I don't have an update on his status this week. PSB Gfx & Video Drivers ======================= Inuka has been investigating a bug with the PSB Gfx Beta3 RC driver where powertop is reporting that X is generating 120+ interrupts/second when the system is idle. This prevents the CPU from going into a lower power C state and blows battery life. The issue is believed to be in the implementation/design on the interface between closed & open pieces of the driver. After the holidays we'll be talking directly with the 3rd party developer to get this corrected. Power and Performance Testing/Optimization ========================================== Jay has numbers that compares performance between the mobile browser compiled with gcc and browser compiled with Intel C/C++ compiler. As expected there are some significant improvement, for example browser startup appears to be about 25% faster with the version compiled with the Intel compiler. Before we get too excited, we need spend some time scrubbing the data and make sure the numbers we've collected are accurate. +=+=+ Rob Rhoads mailto:[EMAIL PROTECTED] Moblin.org Kernel and Driver Team Lead Open Source Technology Center Office: 503-712-6675 Software Solutions Group mobile: 971-533-2451 Intel Corporation Hillsboro, Oregon USA -- Ubuntu-mobile mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-mobile
