pseries: Remove unnecessary locking from PAPR hash table hcalls
In the paravirtualized environment provided by PAPR, there is a standardlocking scheme so that hypercalls updating the hash page table fromdifferent guest threads don't corrupt the haah table state. We implement...
pseries: Small cleanup to H_CEDE implementation
The H_CEDE hypercall implementation for the pseries machine doesn't triggerquite the right path in the main cpu exec loop. We should set exit_requestto pop up one extra level and recheck state, and we should set the...
Remove unused CONFIG_TCG_PASS_AREG0 and dead code
Now that CONFIG_TCG_PASS_AREG0 is enabled for all targets,remove dead code and support for !CONFIG_TCG_PASS_AREG0 case.
Remove dyngen-exec.h and all references to it. Although included byhw/spapr_hcall.c, it does not seem to use it....
spapr: Add "memop" hypercall
This adds a qemu-specific hypervisor call to the pseries machinewhich allows to do what amounts to memmove, memcpy and xor overregions of physical memory such as the framebuffer.
This is the simplest way to get usable framebuffer speed from...
pseries: Fix use of global CPU state
Commit ed120055c7f9b26b5707d3ceabbe5a3f06aaf937 (Implement PAPR VPAfunctions for pSeries shared processor partitions) introduced thederegister_dtl() function and typo "emv" as name of its argument.This went unnoticed because the code in that function can access the...
ppc hw/: Don't use CPUState
Scripted conversion: for file in hw/ppc*.[hc] hw/mpc8544_guts.c hw/spapr*.[hc] hw/virtex_ml507.c hw/xics.c; do sed -i "s/CPUState/CPUPPCState/g" $file done

qom: Unify type registration
Replace device_init() with generalized type_init().
While at it, unify naming convention: type_init([$prefix_]register_types)Also, type_init() is a function, so add preceding blank line wherenecessary and don't put a semicolon after the closing brace....
pseries: Add real mode debugging hcalls
PAPR systems support several hypercalls intended for use in real modedebugging tools. These implement reads and writes to arbitrary guestphysical addresses. This is useful for real mode software because itallows access to IO addresses and memory outside the RMA without going...
pseries: Implement hcall-bulk hypervisor interface
This patch adds support for the H_REMOVE_BULK hypercall on the pseriesmachine. Strictly speaking this isn't necessarym since the kernel willonly attempt to use this if hcall-bulk is advertised in the device tree,...
pseries: More complete WIMG validation in H_ENTER code
Currently our implementation of the H_ENTER hypercall, which inserts amapping in the hash page table assumes that only ordinary memory is evermapped, and only permits mapping attribute bits accordingly (WIMG==0010)....
exec.h cleanup
Move softmmu_exec.h include directives from target-*/exec.h totarget-*/op_helper.c. Move also various other stuff only used inop_helper.c there.
Define global env in dyngen-exec.h.
For i386, move wrappers for segment and FPU helpers from user-exec.c...

Remove exec-all.h include directives
Most exec-all.h include directives are now useless, remove them.

pSeries: Clean up write-only variables
A few pieces of the pSeries emulation code have variables which are setbut never used, which causes warnings on gcc 4.6. This patch removesthese instances.

Fix off-by-one error in sizing pSeries hcall table
The pSeries machine uses two tables to look up guest hcalls for emulation.One of these is exactly one entry too small to hold all the hcalls it needsto, leading to memory corruption.
This patch fixes the bug, and while we're at it, make both tables 'static'...
Implement PAPR VPA functions for pSeries shared processor partitions
Shared-processor partitions are those where a CPU is time-sliced betweenpartitions, rather than being permanently dedicated to a singlepartition. qemu emulated partitions, since they are just scheduled with...
Implement hcall based RTAS for pSeries machines
On pSeries machines, operating systems can instantiate "RTAS" (Run-TimeAbstraction Services), a runtime component of the firmware which implementsa number of low-level, infrequently used operations. On logical partitions...
Implement assorted pSeries hcalls and RTAS methods
This patch adds several small utility hypercalls and RTAS methods tothe pSeries platform emulation. Specifically:
This just prints a character to the console, it's occasionally used...
Start implementing pSeries logical partition machine
This patch adds a "pseries" machine to qemu. This aims to emulate alogical partition on an IBM pSeries machine, compliant to the"PowerPC Architecture Platform Requirements" (PAPR) document.
This initial version is quite limited, it implements a basic machine...
Virtual hash page table handling on pSeries machine
On pSeries logical partitions, excepting the old POWER4-style full systempartitions, the guest does not have direct access to the hardware pagetable. Instead, the pagetable exists in hypervisor memory, and the guest...
