that.\n\nAn arch may implement passing of a variable that is unique to the\nfunction and can be saved on entering a function and can be tested\nwhen exiting the function. Usually the frame pointer can be used for\nthis purpose.\n\nThis patch also implements this for x86. Where it passes in the stack\nframe of the parent function, and will test that frame on exit.\n\nThere was a case in x86_32 with optimize for size (-Os) where, for a\nfew functions, gcc would align the stack frame and place a copy of the\nreturn address into it. The function graph tracer modified the copy and\nnot the actual return address. On return from the funtion, it did not go\nto the tracer hook, but returned to the parent. This broke the function\ngraph tracer, because the return of the parent (where gcc did not do\nthis funky manipulation) returned to the location that the child function\nwas suppose to. This caused strange kernel crashes.\n\nThis test detected the problem and pointed out where the issue was.\n\nThis modifies the parameters of one of the functions that the arch\nspecific code calls, so it includes changes to arch code to accommodate\nthe new prototype.\n\nNote, I notice that the parsic arch implements its own push_return_trace.\nThis is now a generic function and the ftrace_push_return_trace should be\nused instead.

I\u0027m not entirely certain of why, I susepct they often contained\ngarbage on x86 but it\u0027s hard to tell. This causes the current generic\ncode to always call pci_assign_resource() when trying to access the said\nROM from sysfs, which will try to re-assign some new address regardless\nof what the ROM BAR was already set to at boot time. This can be a\nproblem on hypervisor platforms like pSeries where we aren\u0027t supposed\nto move PCI devices around (and in fact probably can\u0027t).\n\nSecond, our code that generates the PCI tree from the OF device-tree\n(instead of doing config space probing) which we mostly use on pseries\nat the moment, didn\u0027t set the (new) flag IORESOURCE_SIZEALIGN on any\nresource. That means that any attempt at re-assigning such a resource\nwith pci_assign_resource() would fail due to resource_alignment()\nreturning 0.\n\nThis fixes this by doing these two things:\n\n - The code that calculates resource flags based on the OF device-node\nis improved to set IORESOURCE_SIZEALIGN on any valid BAR, and while at\nit also set IORESOURCE_READONLY for ROMs since we were lacking that too\n\n - We now allocate ROM resources as part of the resource tree. However\nto limit the chances of nasty conflicts due to busted firmwares, we\nonly do it on the second pass of our two-passes allocation scheme,\nso that all valid and enabled BARs get precedence.\n\nThis brings pSeries back the ability to access PCI ROMs via sysfs (and\nthus initialize various video cards from X etc...).\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "b173f03d7c48d3346541f26e0b29690dbadca279", "tree": "9eec335a778a6bb715feb4fd0b000fa091d02b0f", "parents": [ "951c4df5b7703137bf4eee002d98d083fbc890cc" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu May 14 18:34:06 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri May 15 16:43:42 2009 +1000" }, "message": "powerpc/pseries: Really fix the oprofile CPU type on pseries\n\nMy previous pach for fixing the oprofile CPU type got somewhat mismerged\n(by my fault) when it collided with another related patch.

(Run state is the state when a hardware RUN bit is 1;\nthe idle task clears RUN while waiting for work to do and sets it when\nthere is work to do.)\n\nThese counters can\u0027t be written to by the kernel, can\u0027t generate\ninterrupts, and don\u0027t obey the freeze conditions. That means we can\nonly use them for per-task counters (where we know we\u0027ll always be in\nrun state; we can\u0027t put a per-task counter on an idle task), and only\nif we don\u0027t want interrupts and we do want to count in all processor\nmodes.\n\nObviously some counters can\u0027t go on a limited hardware counter, but there\nare also situations where we can only put a counter on a limited hardware\ncounter - if there are already counters on that exclude some processor\nmodes and we want to put on a per-task cycle or instruction counter that\ndoesn\u0027t exclude any processor mode, it could go on if it can use a\nlimited hardware counter.\n\nTo keep track of these constraints, this adds a flags argument to the\nprocessor-specific get_alternatives() functions, with three bits defined:\none to say that we can accept alternative event codes that go on limited\ncounters, one to say we only want alternatives on limited counters, and\none to say that this is a per-task counter and therefore events that are\ngated by run state are equivalent to those that aren\u0027t (e.g. a \"cycles\"\nevent is equivalent to a \"cycles in run state\" event). These flags\nare computed for each counter and stored in the counter-\u003ehw.counter_base\nfield (slightly wonky name for what it does, but it was an existing\nunused field).\n\nSince the limited counters don\u0027t freeze when we freeze the other counters,\nwe need some special handling to avoid getting skew between things counted\non the limited counters and those counted on normal counters. To minimize\nthis skew, if we are using any limited counters, we read PMC5 and PMC6\nimmediately after setting and clearing the freeze bit. This is done in\na single asm in the new write_mmcr0() function.\n\nThe code here is specific to PMC5 and PMC6 being the limited hardware\ncounters. Being more general (e.g. having a bitmap of limited hardware\ncounter numbers) would have meant more complex code to read the limited\ncounters when freezing and unfreezing the normal counters, with\nconditional branches, which would have increased the skew. Since it\nisn\u0027t necessary for the code to be more general at this stage, it isn\u0027t.\n\nThis also extends the back-ends for POWER5+ and POWER6 to be able to\nhandle up to 6 counters rather than the 4 they previously handled.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Robert Richter \u003crobert.richter@amd.com\u003e\nLKML-Reference: \u003c18936.19035.163066.892208@cargo.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "4aeb0b4239bb3b67ed402cb9cef3e000c892cadf", "tree": "0a025a30fa5de3b40ab1ea156a3f86ee2d000839", "parents": [ "527e26af3741a2168986d8b82653ffe173891324" ], "author": { "name": "Robert Richter", "email": "robert.richter@amd.com", "time": "Wed Apr 29 12:47:03 2009 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Apr 29 14:51:03 2009 +0200" }, "message": "perfcounters: rename struct hw_perf_counter_ops into struct pmu\n\nThis patch renames struct hw_perf_counter_ops into struct pmu.
