From 443e802bab16916f9a51a34f2213f4dee6e8762c Mon Sep 17 00:00:00 2001 From: Hendrik Brueckner Date: Thu, 12 Dec 2013 17:54:57 +0100 Subject: [PATCH] s390/cpum_sf: Detect KVM guest samples The host-program-parameter (hpp) value of basic sample-data-entries designates a SIE control block that is set by the LPP instruction in sie64a(). Non-zero values indicate guest samples, a value of zero indicates a host sample. For perf samples, host and guest samples are distinguished using particular PERF_MISC_* flags. The perf layer calls perf_misc_flags() to set the flags based on the pt_regs content. For each sample-data-entry, the cpum_sf PMU creates a pt_regs structure with the sample-data information. An additional flag structure is added to easily distinguish between host and guest samples. Signed-off-by: Hendrik Brueckner Signed-off-by: Martin Schwidefsky --- Reading git-format-patch failed
