We don\u0027t use\n it.\n- task switch, but we don\u0027t use tss.\n- icebp/int01 trap. This instruction (0xf1) is undocumented and\n generates an int 1 exception. Unlike single step through TF\n flag, it doesn\u0027t set the single step origin of the exception\n in dr6.\n\nicebp then used to be reported in userspace using trap signals\nbut this have been incidentally broken with the new breakpoint\ncode. Reenable this. Since this is the only debug event that\ndoesn\u0027t set anything in dr6, this is all we have to check.\n\nThis fixes a regression in Wine where World Of Warcraft got broken\nas it uses this for software protection checks purposes.

If you had pinned events, e.g., watchdog, and were\nover-committing the PMU, you would get bogus counts. The bug was\nshowing up on Intel CPU because events would move around more\noften that on AMD. But the problem also existed on AMD, though\nharder to expose.\n\nThe issues were:\n\n - group_sched_in() was missing a cancel_txn() in the error path\n\n - cpuc-\u003en_added was not properly maintained, leading to missing\n actions in hw_perf_enable(), i.e., n_running being 0. You cannot\n update n_added until you know the transaction has succeeded. In\n case of failed transaction n_added was not adjusted back.\n\n - in case of failed transactions, event_sched_out() was called\n and eventually invoked x86_disable_event() to touch the HW reg.\n But with transactions, on X86, event_sched_in() does not touch\n HW registers, it simply collects events into a list. Thus, you\n could end up calling x86_disable_event() on a counter which\n did not correspond to the current event when idx !\u003d -1.\n\nThe patch modifies the generic and X86 code to avoid all those problems.\n\nFirst, we keep track of the number of events added last. In case the\ntransaction fails, we substract them from n_added. This approach is\nnecessary (as opposed to delaying updates to n_added) because not all\nevent updates use the transaction API, e.g., single events.\n\nSecond, we encapsulate the event_sched_in() and event_sched_out() in\ngroup_sched_in() inside the transaction. That makes the operations\nsymmetrical and you can also detect that you are inside a transaction\nand skip the HW reg access by checking cpuc-\u003egroup_flag.\n\nWith this patch, you can now overcommit the PMU even with pinned\nsystem-wide events present and still get valid counts.\n\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\nSigned-off-by: Peter Zijlstra
