Hi,
This series brings DMA operations support to the fw_cfg kernel module
and provide "etc/vmcoreinfo" support.
At the current iteration of "[Qemu-devel] [PATCH v6 0/7] KASLR kernel
dump support" patch series, a "etc/vmcoreinfo" entry is added with
qemu -device vmcoreinfo, where the guest during boot or later, can
write the addr/size location of a ELF note to be appended in the qemu
dump.
v2:
- use platform device for dma mapping
- add etc/vmcoreinfo patch
- some code cleanups
Marc-André Lureau (4):
fw_cfg: add DMA register
fw_cfg: do DMA read operation
fw_cfg: write vmcoreinfo details
RFC: fw_cfg: add DMA write operation in sysfs
