[Question] How To Log QEMU Memory Access

by 周春华

Dear linus.walleij, I am sorry to trouble you. Would you mind give a hand? I got a job that should log the RAM memory access in the QEMU. First, I should find out the code line in QEMU to trap all RAM memory access. After some efforts, I have some conclusions: 1. I have found the function dealing with the translation from the virtual address to physical address in the guest of QEMU, such as [target-arm/helper.c:get_phys_addr], and the page fault handler function [target-arm/helper.c:cpu_arm_handle_mmu_fault]. However, we have not found out the routine of accessing physical address from MMU TLB entry. 2. We have understood the relation of the guest physical address and host virtual address, and found the function [exec.c:qemu_get_ram_ptr] translating the guest physical address to host virtual address. I am pressed for time. Would you mind to help me to check it? If you know the location of the code lines or related messages, please tell me. Thank you for your kindness. The QEMU I used getting from [* http://lists.linaro.org/pipermail/linaro-announce/2012-February/000095.html* ]. Thanks, Jerry Zhou

ARM port of google-talkplugin

by Matt Waddel

Hi, Does anybody know if google-talkplugin has been ported to ARM? This package is required to run Google Hangouts and there are proprietary libraries in the plugin that appear to be compiled for x86 only. I found some old references that these libraries might eventually be ported to ARM and was just wondering if anybody had heard of this work being done. TIA, Matt

[PATCH 1/3] cpuidle: use the driver's state_count as default

by Daniel Lezcano

If the state_count is not initialized for the device use the driver's state count as the default. That will prevent to add it manually in the cpuidle driver initialization routine and will save us from duplicate line of code.
