[PATCH] powerpc/pseries: Move CMO code from plapr_wrappers.h to platforms/pseries

Currently there's some CMO (Cooperative Memory Overcommit) code, in plpar_wrappers.h. Some of it is #ifdef CONFIG_PSERIES and some of it isn't. The end result being if a file includes plpar_wrappers.h it won't build with CONFIG_PSERIES=n. Fix it by moving the CMO code into platforms/pseries. The

[powerpc v4 3/3] Enable storage keys for radix - user mode execution

ISA 3 defines new encoded access authority that allows instruction access prevention in privileged mode and allows normal access to problem state. This patch just enables IAMR (Instruction Authority Mask Register), enabling AMR would require more work. I've tested this with a buggy driver and a

[powerpc v4 2/3] Detect instruction fetch denied and report

ISA 3 allows for prevention of instruction fetch and execution of user mode pages. If such an error occurs, SRR1 bit 35 reports the error. We catch and report the error in do_page_fault() Signed-off-by: Balbir Singh --- arch/powerpc/mm/fault.c | 4 1 file changed, 4

[powerpc v4 1/3] Setup AMOR in HV mode

AMOR should be setup in HV mode, we set it up once and let the generic kernel handle IAMR. This patch is used to enable storage keys in a following patch as defined in ISA 3 Reported-by: Aneesh Kumar K.V Signed-off-by: Balbir Singh ---

[powerpc v4 0/3] Enable IAMR storage keys for radix

The first patch sets up AMOR in hypervisor mode. AMOR needs to be setup before IAMR (details of AMOR/IAMR in each patch). The second patch enables detection of exceptions generated due to instruction fetch violations caused and OOPSs' the task. The third patch enables IAMR for both hypervisor and

[PATCH] Rename early_init_mmu to early_init_mmu_primary

It helps clarify that the action taken is just for the primary CPU and more action might be required for in the secondaries in early_init_mmu_secondary. This patch does not introduce a functional change Signed-off-by: Balbir Singh ---

[PATCH V4 2/2] powerpc/kvm: Update kvmppc_set_arch_compat() for ISA v3.00

The function kvmppc_set_arch_compat() is used to determine the value of the processor compatibility register (PCR) for a guest running in a given compatibility mode. There is currently no support for v3.00 of the ISA. Add support for v3.00 of the ISA which adds an ISA v2.07 compatilibity mode to

[PATCH V4 1/2] powerpc: Define new ISA v3.00 logical PVR value and PCR register value

ISA 3.00 adds the logical PVR value 0x0f05, so add a definition for this. Define PCR_ARCH_207 to reflect ISA 2.07 compatibility mode in the processor compatibility register (PCR). The next patch changes the algorithm used to determine the required PCR value in the function

[PATCH V4 0/2] powerpc: add support for ISA v2.07 compat level

Version v3.00 of the ISA added a new compat level to the processor compatibility register (PCR), an ISA v2.07 compatibility mode. Upstream QEMU already supports this so it may as well go into the kernel now. Change Log: V1 -> V2: - Reworked logic to set and mask the PCR, no functional change

[PATCH 0/3] soc: avoid module usage in non-modular code

This series of commits is a part of a larger project to ensure people don't reference modular support functions in non-modular code. Overall there was roughly 5k lines of dead code in the kernel due to this. So far we've fixed several areas, like tty, x86, net, gpio ... and we continue to work
