In other words, the noerror behaviour would apply to\n the next system call where we had to reschedule or deliver a signal,\n which is not necessarily the current system call.\n\n* 32-bit wasn\u0027t doing the call to ptrace_notify in the syscall exit\n path when the _TIF_SINGLESTEP bit was set.\n\n* _TIF_RESTOREALL was in both _TIF_USER_WORK_MASK and\n _TIF_PERSYSCALL_MASK, which is odd since _TIF_RESTOREALL is only set\n by system calls. I took it out of _TIF_USER_WORK_MASK.\n\n* On 64-bit, _TIF_RESTOREALL wasn\u0027t causing the non-volatile registers\n to be restored (unless perhaps a signal was delivered or the syscall\n was traced or single-stepped). Thus the non-volatile registers\n weren\u0027t restored on exit from a signal handler. We probably got\n away with it mostly because signal handlers written in C wouldn\u0027t\n alter the non-volatile registers.\n\n* On 32-bit I simplified the code and made it more like 64-bit by\n making the syscall exit path jump to ret_from_except to handle\n preemption and signal delivery.\n\n* 32-bit was calling do_signal unnecessarily when _TIF_RESTOREALL was\n set - but I think because of that 32-bit was actually restoring the\n non-volatile registers on exit from a signal handler.\n\n* I changed the order of enabling interrupts and saving the\n non-volatile registers before calling do_syscall_trace_leave; now we\n enable interrupts first.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "141aa59b5347a4a021e37cfbc2258df9af9392f8", "tree": "75c16e758b2f8e5439cd7425ac4c8edc4c61f5fa", "parents": [ "aa5cb02143123289bd37c30c0ad60339f8da0bad" ], "author": { "name": "David Gibson", "email": "david@gibson.dropbear.id.au", "time": "Fri Mar 03 16:24:06 2006 +1100" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Fri Mar 03 22:00:52 2006 +1100" }, "message": "[PATCH] powerpc: Fix incorrect pud_ERROR() message\n\nThe powerpc pud_ERROR() function misleadingly prints a message\nindicating a pmd error.

To solve this:\n\n- I\u0027ve added a \u0027domain distance\u0027 function, which is used to cache\n measurement results. Each distance is only measured once. This means\n that e.g. on NUMA distances of 0, 1 and 2 might be measured, on HT\n distances 0 and 1, and on SMP distance 0 is measured. The code walks\n the domain tree to determine the distance, so it automatically follows\n whatever hierarchy an architecture sets up. This cuts down on the boot\n time significantly and removes the O(N^2) limit. The only assumption\n is that migration costs can be expressed as a function of domain\n distance - this covers the overwhelming majority of existing systems,\n and is a good guess even for more assymetric systems.\n\n [ People hacking systems that have assymetries that break this\n assumption (e.g. different CPU speeds) should experiment a bit with\n the cpu_distance() function. Adding a -\u003emigration_distance factor to\n the domain structure would be one possible solution - but lets first\n see the problem systems, if they exist at all. Lets not overdesign. ]\n\nAnother problem was that only a single cache-size was used for measuring\nthe cost of migration, and most architectures didnt set that variable\nup. Furthermore, a single cache-size does not fit NUMA hierarchies with\nL3 caches and does not fit HT setups, where different CPUs will often\nhave different \u0027effective cache sizes\u0027. To solve this problem:\n\n- Instead of relying on a single cache-size provided by the platform and\n sticking to it, the code now auto-detects the \u0027effective migration\n cost\u0027 between two measured CPUs, via iterating through a wide range of\n cachesizes. The code searches for the maximum migration cost, which\n occurs when the working set of the test-workload falls just below the\n \u0027effective cache size\u0027. I.e. real-life optimized search is done for\n the maximum migration cost, between two real CPUs.\n\n This, amongst other things, has the positive effect hat if e.g. two\n CPUs share a L2/L3 cache, a different (and accurate) migration cost\n will be found than between two CPUs on the same system that dont share\n any caches.\n\n(The reliable measurement of migration costs is tricky - see the source\nfor details.)\n\nFurthermore i\u0027ve added various boot-time options to override/tune\nmigration behavior.\n\nFirstly, there\u0027s a blanket override for autodetection:\n\n\tmigration_cost\u003d1000,2000,3000\n\nwill override the depth 0/1/2 values with 1msec/2msec/3msec values.\n\nSecondly, there\u0027s a global factor that can be used to increase (or\ndecrease) the autodetected values:\n\n\tmigration_factor\u003d120\n\nwill increase the autodetected values by 20%. This option is useful to\ntune things in a workload-dependent way - e.g. if a workload is\ncache-insensitive then CPU utilization can be maximized by specifying\nmigration_factor\u003d0.\n\nI\u0027ve tested the autodetection code quite extensively on x86, on 3\nP3/Xeon/2MB, and the autodetected values look pretty good:\n\nDual Celeron (128K L2 cache):\n\n ---------------------\n migration cost matrix (max_cache_size: 131072, cpu: 467 MHz):\n ---------------------\n [00] [01]\n [00]: - 1.7(1)\n [01]: 1.7(1) -\n ---------------------\n cacheflush times [2]: 0.0 (0) 1.7 (1784008)\n ---------------------\n\nHere the slow memory subsystem dominates system performance, and even\nthough caches are small, the migration cost is 1.7 msecs.\n\nDual HT P4 (512K L2 cache):\n\n ---------------------\n migration cost matrix (max_cache_size: 524288, cpu: 2379 MHz):\n ---------------------\n [00] [01] [02] [03]\n [00]: - 0.4(1) 0.0(0) 0.4(1)\n [01]: 0.4(1) - 0.4(1) 0.0(0)\n [02]: 0.0(0) 0.4(1) - 0.4(1)\n [03]: 0.4(1) 0.0(0) 0.4(1) -\n ---------------------\n cacheflush times [2]: 0.0 (33900) 0.4 (448514)\n ---------------------\n\nHere it can be seen that there is no migration cost between two HT\nsiblings (CPU#0/2 and CPU#1/3 are separate physical CPUs).

It will take\nan FP unavailable exception, which will write the current FPU state\nto the thread_struct, overwriting the values which sigreturn has\nstored. Note that this can only happen on UP since we don\u0027t implement\nlazy CPU state on SMP.\n\nThe fix is to flush the lazy CPU state before updating the\nthread_struct.
