eec37961a56aa4f3fe1c33ffd48eec7d1bb0c009 - powerpc64/ftrace: Move ftrace sequence out of line

Wed, 30 Oct 2024 08:08:45 +0100

powerpc64/ftrace: Move ftrace sequence out of lineFunction profile sequence on powerpc includes two instructions at thebeginning of each function: mflr r0 bl ftrace_callerThe call to ftrace_caller() gets nop'ed out during kernel boot and ispatched in when ftrace is enabled.Given the sequence, we cannot return from ftrace_caller with 'blr' as weneed to keep LR and r0 intact. This results in link stack (returnaddress predictor) imbalance when ftrace is enabled. To address that, wewould like to use a three instruction sequence: mflr r0 bl ftrace_caller mtlr r0Further more, to support DYNAMIC_FTRACE_WITH_CALL_OPS, we need toreserve two instruction slots before the function. This results in atotal of five instruction slots to be reserved for ftrace use on eachfunction that is traced.Move the function profile sequence out-of-line to minimize its impact.To do this, we reserve a single nop at function entry using-fpatchable-function-entry=1 and add a pass on vmlinux.o to determinethe total number of functions that can be traced. This is then used togenerate a .S file reserving the appropriate amount of space for use asftrace stubs, which is built and linked into vmlinux.On bootup, the stub space is split into separate stubs per function andpopulated with the proper instruction sequence. A pointer to theassociated stub is maintained in dyn_arch_ftrace.For modules, space for ftrace stubs is reserved from the generic modulestub space.This is restricted to and enabled by default only on 64-bit powerpc,though there are some changes to accommodate 32-bit powerpc. This isdone so that 32-bit powerpc could choose to opt into this based onfurther tests and benchmarks.As an example, after this patch, kernel functions will have a single nopat function entry:: addis r2,r12,467 addi r2,r2,-16028 nop mfocrf r11,8 ...When ftrace is enabled, the nop is converted to an unconditional branchto the stub associated with that function:: addis r2,r12,467 addi r2,r2,-16028 b ftrace_ool_stub_text_end+0x11b28 mfocrf r11,8 ...The associated stub:: mflr r0 bl ftrace_caller mtlr r0 b kernel_clone+0xc ...This change showed an improvement of ~10% in null_syscall benchmark on aPower 10 system with ftrace enabled.Signed-off-by: Naveen N Rao Signed-off-by: Hari Bathini Signed-off-by: Michael Ellerman Link: https://patch.msgid.link/20241030070850.1361304-13-hbathini@linux.ibm.com List of files: /linux/arch/powerpc/Kbuild
