[Qemu-devel] [PATCH V1 0/7] execute code from mmio area |
Date: |

From: KONRAD Frederic <address@hidden>
This series allows to execute code from mmio areas.
The main goal of this is to be able to run code for example from an SPI device.
The three first patch fixes the way get_page_addr_code fills the TLB.
The fourth patch implements the mmio execution helpers: the device must
implement the request_ptr callback of the MemoryRegion and will be notified when
the guest wants to execute code from it.
The fifth patch introduces mmio_interface device which allows to dynamically
map a host pointer somewhere into the memory.
The sixth patch implements the execution from the SPI memories in the
xilinx_spips model.
Thanks,
Fred
RFC -> V1:
* Use an interface (mmio-interface) to fix any reference leak issue.
KONRAD Frederic (7):
cputlb: cleanup get_page_addr_code to use VICTIM_TLB_HIT
cputlb: move get_page_addr_code
cputlb: fix the way get_page_addr_code fills the tlb
exec: allow to get a pointer for some mmio memory region
qdev: add MemoryRegion property
introduce mmio_interface
xilinx_spips: allow mmio execution
