2017-04-20	KVM: PPC: Book3S: Add MMIO emulation for FP and VSX instructions	Bin Lu	1	-0/+5
	This patch provides the MMIO load/store emulation for instructions of 'double & vector unsigned char & vector signed char & vector unsigned short & vector signed short & vector unsigned int & vector signed int & vector double '. The instructions that this adds emulation for are: - ldx, ldux, lwax, - lfs, lfsx, lfsu, lfsux, lfd, lfdx, lfdu, lfdux, - stfs, stfsx, stfsu, stfsux, stfd, stfdx, stfdu, stfdux, stfiwx, - lxsdx, lxsspx, lxsiwax, lxsiwzx, lxvd2x, lxvw4x, lxvdsx, - stxsdx, stxsspx, stxsiwx, stxvd2x, stxvw4x [paulus@ozlabs.org - some cleanups, fixes and rework, make it compile for Book E, fix build when PR KVM is built in] Signed-off-by: Bin Lu <lblulb@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@ozlabs.org>
2015-10-15	KVM: PPC: e500: Emulate TMCFG0 TMRN register	Tudor Laurentiu	1	-0/+5
	Emulate TMCFG0 TMRN register exposing one HW thread per vcpu. Signed-off-by: Mihai Caraman <mihai.caraman@freescale.com> [Laurentiu.Tudor@freescale.com: rebased on latest kernel, use define instead of hardcoded value, moved code in own function] Signed-off-by: Laurentiu Tudor <Laurentiu.Tudor@freescale.com> Acked-by: Scott Wood <scotttwood@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2014-05-30	KVM: PPC: BOOK3S: Remove open coded make_dsisr in alignment handler	Aneesh Kumar K.V	1	-0/+34
	Use make_dsisr instead of open coding it. This also have the added benefit of handling alignment interrupt on additional instructions. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-10-17	KVM: PPC: E500: exit to user space on "ehpriv 1" instruction	Bharat Bhushan	1	-0/+4
	"ehpriv 1" instruction is used for setting software breakpoints by user space. This patch adds support to exit to user space with "run->debug" have relevant information. As this is the first point we are using run->debug, also defined the run->debug structure. Signed-off-by: Bharat Bhushan <bharat.bhushan@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2008-12-31	ppc: Create disassemble.h to extract instruction fields	Hollis Blanchard	1	-0/+80
	This is used in a couple places in KVM, but isn't KVM-specific. However, this patch doesn't modify other in-kernel emulation code: - xmon uses a direct copy of ppc_opc.c from binutils - emulate_instruction() doesn't need it because it can use a series of mask tests.
