91 |
++ * Our handling of compat tasks (PERF_SAMPLE_REGS_ABI_32) is weird, but |
92 |
++ * we're stuck with it for ABI compatability reasons. |
93 |
++ * |
94 |
++ * For a 32-bit consumer inspecting a 32-bit task, then it will look at |
95 |
++ * the first 16 registers (see arch/arm/include/uapi/asm/perf_regs.h). |
96 |
++ * These correspond directly to a prefix of the registers saved in our |
97 |
++ * 'struct pt_regs', with the exception of the PC, so we copy that down |
98 |
++ * (x15 corresponds to SP_hyp in the architecture). |
99 |
++ * |
100 |
++ * So far, so good. |
101 |
++ * |
102 |
++ * The oddity arises when a 64-bit consumer looks at a 32-bit task and |
103 |
++ * asks for registers beyond PERF_REG_ARM_MAX. In this case, we return |
104 |
++ * SP_usr, LR_usr and PC in the positions where the AArch64 SP, LR and |
105 |
++ * PC registers would normally live. The initial idea was to allow a |
106 |
++ * 64-bit unwinder to unwind a 32-bit task and, although it's not clear |
107 |
++ * how well that works in practice, somebody might be relying on it. |
108 |
++ * |
109 |
++ * At the time we make a sample, we don't know whether the consumer is |
110 |
++ * 32-bit or 64-bit, so we have to cater for both possibilities. |
