Similar to the LI32() optimization, if the value can be represented in 32-bits, use LI32(). Also handle loading a few specific forms of immediate values in an optimum manner. While at it, remove the semicolon at the end of the macro! Cc: Matt Evans Cc: Michael Ellerman

[RFC PATCH 1/6] ppc: bpf/jit: Fix/enhance 32-bit Load Immediate implementation

The existing LI32() macro can sometimes result in a sign-extended 32-bit load that does not clear the top 32-bits properly. As an example, loading 0x7fff results in the register containing 0x7fff. While this does not impact classic BPF JIT implementation (since that only uses the

[RFC PATCH 3/6] ppc: bpf/jit: Introduce rotate immediate instructions

Since we will be using the rotate immediate instructions for extended BPF JIT, let's introduce macros for the same. And since the shift immediate operations use the rotate immediate instructions, let's redo those macros to use the newly introduced instructions. Cc: Matt Evans

[RFC PATCH 5/6] ppc: bpf/jit: Isolate classic BPF JIT specifics into a separate header

Break out classic BPF JIT specifics into a separate header in preparation for eBPF JIT implementation. Note that ppc32 will still need the classic BPF JIT. Cc: Matt Evans Cc: Michael Ellerman Cc: Paul Mackerras Cc: Alexei Starovoitov

[PATCH] KVM: PPC:enable mmio_sign_extend in kvmppc_handle_load()

The logic of 'kvmppc_handle_loads' is same as 'kvmppc_handle_load', but with sign extension. It sets mmio_sign_extend to 1, then calls 'kvmppc_handle_load', but in 'kvmppc_handle_load', the mmio_sign_extend flag is reset to 0, so the data does not actually get sign-extended. This patch fixes the

[RFC PATCH 0/6] eBPF JIT for PPC64

Implement extended BPF JIT for ppc64. We retain the classic BPF JIT for ppc32 and move ppc64 BE/LE to use the new JIT. Classic BPF filters will be converted to extended BPF (see convert_filter()) and JIT'ed with the new compiler. Most of the existing macros are retained and fixed/enhanced where
