MIPS Magnum: fix memory-mapped i8042
Current implementation of memory-mapped i8042 controller is atmimplemented with an interface shift (it_shift) parameter, like most allmemory-mapped devices in Qemu.However, this isn't suitable for MIPS Magnum, where i8042 controller is at...
KVM: Coalesced MMIO support
MMIO exits are more expensive in KVM or Xen than in QEMU because theyinvolve, at least, privilege transitions. However, MMIO writeoperations can be effectively batched if those writes do not have sideeffects.
Good examples of this include VGA pixel operations when in a planar...

SH4: SCI improvement
This patch simply implement one register of SH4's SCI := Serial Communication Interface.
R2D evaluation board uses SCI for SPI connection. So, Linux kernel for R2D withdefault configuration causes a QEMU assertion failure when it initializes SPI driver....

SH4: Eliminate P4 to A7 mangling (Takashi YOSHII).
Main purpose of this is to delete *physical = address & 0x1fffffff;at target-sh4/helper.c:449, using new mmio rule introduced by #5849This masking is a nice trick to realize P4/A7 duality of SH registers....
SH: improve the way sh7750 registers io memory (Takashi YOSHII).
Fixes to be needed for commit #5849 "Change MMIO callbacks..." hw/sh7750.c: - Divide region of CPU control registers to avoid overlapping to peripheral modules. - Delete unused var "icr", which had moved to hw/sh_intc.c....
