powerpc/mm: Fixup wrong LPCR_VRMASD value

2017-05-14T12:08:20Z

commit 4ab2537c4204b976e4ca350bbdc193b4649cad28 upstream. In commit a4b349540a26af ("powerpc/mm: Cleanup LPCR defines") we updated LPCR_VRMASD wrongly as below. -#define LPCR_VRMASD (0x1ful << (63-16)) +#define LPCR_VRMASD_SH 47 +#define LPCR_VRMASD (ASM_CONST(1) << LPCR_VRMASD_SH) We initialize the VRMA bits in LPCR to 0x00 in kvm. Hence using a different mask value as above while updating lpcr should not have any impact. This patch updates it to the correct value.

powerpc/powernv: Fix CPU hotplug to handle waking on HVI

2017-02-09T04:19:57Z

The IPIs come in as HVI not EE, so we need to test the appropriate SRR1 bits. The encoding is such that it won't have false positives on P7 and P8 so we can just test it like that. We also need to handle the icp-opal variant of the flush.

powerpc/powernv: Define and set POWER9 HFSCR doorbell bit

2016-11-23T00:18:22Z

Define and set the POWER9 HFSCR doorbell bit so that guests can use msgsndp. ISA 3.0 calls this MSGP, so name it accordingly in the code. Signed-off-by: Michael Neuling Signed-off-by: Michael Ellerman

powerpc/reg: Add definition for LPCR_PECE_HVEE

2016-11-22T23:32:12Z

ISA 3.0 defines a new PECE (Power-saving mode Exit Cause Enable) field in the LPCR (Logical Partitioning Control Register), called LPCR_PECE_HVEE (Hypervisor Virtualization Exit Enable). KVM code will need to know about this bit, so add a definition for it. Signed-off-by: Michael Ellerman

powerpc/64: Define new ISA v3.00 logical PVR value and PCR register value

2016-11-22T23:32:12Z

ISA 3.00 adds the logical PVR value 0x0f000005, so add a definition for this. Define PCR_ARCH_207 to reflect ISA 2.07 compatibility mode in the processor compatibility register (PCR). [paulus@ozlabs.org - moved dummy PCR_ARCH_300 value into next patch] Signed-off-by: Suraj Jitindar Singh Signed-off-by: Paul Mackerras Signed-off-by: Michael Ellerman

powerpc/64: Add some more SPRs and SPR bits for POWER9

2016-11-21T23:19:31Z

These definitions will be needed by KVM. Signed-off-by: Paul Mackerras Signed-off-by: Michael Ellerman

powerpc: Revert Load Monitor Register Support

2016-11-14T09:05:57Z

Load monitored is no longer supported on POWER9 so let's remove the code. This reverts commit bd3ea317fddf ("powerpc: Load Monitor Register Support"). Signed-off-by: Michael Neuling Signed-off-by: Michael Ellerman
