PSB C0 HW Support ================= No change from last week. We're still waiting for C0 HW.
SDIO ==== We've updated and re-sync'd our SDIO patches with Pierre Ossman's latest code. These patches have been committed to our moblin kernel git tree but not yet released into the gaston repository. Dabney Thermal patches ====================== The Alpha release of the Dabney Thermal patches have been applied to the Moblin kernel. We're waiting on a special BIOS and FW to test. USB Client Drivers ================== We've applied the USB Client C0 release kernel patches to the Moblin kernel git tree but not yet released a new set of kernel packages to the gaston repository. There are a number of issues with this version of the USB Client driver and since we don't have C0 HW we're only able to test on B0/B1. Known Issues: + We had to load the iusbc module with force_fullspeed=1 parameter to force UDC to USB 1.1 mode. + Need to have an unload/reload cycle to make USBC work both for Mass Storage and RNDIS feature and both for Windows XP host and Linux host. + RNDIS issue: On a Windows host, the Windows rndis device driver doesn't recognize the MID device, error response is "Windows could not recognize the USB device ..." + RNDIS cause kernel panic issue: If you plug in CB to Windows XP and then plug it to Linux host or vice-versa, RNDIS will cause CB to hang, the keyboard LED blinking indicates a kernel panic. PSB Gfx & Video Drivers ======================= No code changes this week. We're working with the PSB Gfx driver team in an attempt to get them to move to the Xorg 1.4 base and the 2.6.24 kernel's drm.ko. This is to fix the issue with libexa and drm.ko. This is a must for a move to Hardy. When I have something to report I'll let the team know more. The Beta1 release of the 3D drivers were privately integrated on moblin.org, but were found to be very unstable. We're waiting on the Beta3 release before we do anything more. Power and Performance Testing/Optimization ========================================== Reported the issue with psb.ko generating 140+ interrupts/second when the system is idle to PSB Gfx driver team and they thought it was caused by vsync interrupt. They've added an option to disable vsync interrupt, but it will cause tearing when dragging a window. They need to find out what's the D state during CPU idle and only disable vsync interrupt when that D state is entered. Still waiting on C0 HW to investigate the high number of external interrupts with the local APIC timer. +=+=+ Rob Rhoads mailto:[EMAIL PROTECTED] Software Architect 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
