Note: the support for this entry handling has been merged for next qemu release (2.11) v4: - export paddr_vmcoreinfo_note() to fix fw_cfg.ko build - fix build with !CONFIG_CRASH_CORE - replace the unbounded yield() loop with a usleep_range() loop and a 200ms timeout - do not write vmcoreinfo entry when running the kdump kernel (D. Hatayama) - drop the experimental sysfs write support patch from this series v3: (thanks kbuild) - add "fw_cfg: fix the command line module name" patch - fix build of "fw_cfg: add DMA register" with CONFIG_FW_CFG_SYSFS_CMDLINE=y - fix 'Wshift-count-overflow' v2: - use platform device for dma mapping - add etc/vmcoreinfo patch - some code cleanups Marc-André Lureau (5): fw_cfg: fix the command line module name fw_cfg: add DMA register fw_cfg: do DMA read operation crash: export paddr_vmcoreinfo_note() fw_cfg: write vmcoreinfo details drivers/firmware/qemu_fw_cfg.c | 292 +++++++++++++++++++++++++++++++++++++---- kernel/crash_core.c | 1 + 2 files changed, 264 insertions(+), 29 deletions(-) -- 2.15.0.rc0.40.gaefcc5f6f
