The fact is\nthat the author of IRQ compression patch was unable\nto confirm the actual existence of such a system.\n\nAs a result, all i386 kernels with IOAPIC support\npay the following:\n\n1. confusion\n\nIRQ compression re-names the traditional IOAPIC\npin numbers (aka ACPI GSI\u0027s) into sequential IRQ #s:\n\nACPI: PCI Interrupt 0000:00:1c.0[A] -\u003e GSI 20 (level, low) -\u003e IRQ 16\nACPI: PCI Interrupt 0000:00:1c.1[B] -\u003e GSI 21 (level, low) -\u003e IRQ 17\nACPI: PCI Interrupt 0000:00:1c.2[C] -\u003e GSI 22 (level, low) -\u003e IRQ 18\nACPI: PCI Interrupt 0000:00:1c.3[D] -\u003e GSI 23 (level, low) -\u003e IRQ 19\nACPI: PCI Interrupt 0000:00:1c.4[A] -\u003e GSI 20 (level, low) -\u003e IRQ 16\n\nThis makes /proc/interrupts look different\ndepending on system configuration and device probe order.\nIt is also different than the x86_64 kernel running\non the exact same system. As a result, programmers\nget confused when comparing systems.\n\n2. complexity\n\nThe IRQ code in Linux is already overly complex,\nand IRQ compression makes it worse. There have\nalready been two bug workarounds related to IRQ\ncompression -- the IRQ0 timer workaround and\nthe VIA PCI IRQ workaround.\n\n3. size\n\nAll i386 kernels with IOAPIC support contain an int[4096] --\na 4 page array to contain the renamed IRQs.\n\nSo while the irq compression code on i386 should really\nbe deleted -- even before merging the x86_64 irq-overhaul,\nthis patch simply disables it on all high volume systems\nto avoid problems #1 and #2 on most all i386 systems.\n\nA large system with pin numbers \u003e\u003d64 will still have compression\nto conserve limited IRQ numbers for sparse IOAPICS. However,\nthe vast majority of the planet, those with only pin numbers \u003c 64\nwill use an identity GSI -\u003e IRQ mapping.\n\nSigned-off-by: Len Brown \u003clen.brown@intel.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nAcked-by: \"Eric W.

Since we have cmpxchg8b\nto execute a 8 byte cmpxchg atomically on pentium and +, it makes sense\nto provide a flavor of cmpxchg and cmpxchg_local using this instruction.\n\nAlso, for 32 bits architectures lacking the 64 bits atomic cmpxchg, it\nmakes sense _not_ to define cmpxchg64 while cmpxchg could still be\navailable.\n\nMoreover, the fallback for cmpxchg8b on i386 for 386 and 486 is a\n\nHowever, cmpxchg64_local will be emulated by disabling interrupts on all\narchitectures where it is not supported atomically.\n\nTherefore, we *could* turn cmpxchg64_local into a cmpxchg_local, but it\nwould make the 386/486 fallbacks ugly, make its design different from\ncmpxchg/cmpxchg64 (which really depends on atomic operations and cannot\nbe emulated) and require the __cmpxchg_local to be expressed as a macro\nrather than an inline function so the parameters would not be fixed to\nunsigned long long in every case.\n\nSo I think cmpxchg64_local makes sense there, but I am open to\nsuggestions.\n\nQ:\nAre there any callers?\n\nA:\nI am actually using it in LTTng in my timestamping code.

The thread_struct fields are 0\nwhen do_arch_prctl decided to use a GDT slot instead of MSR_FS_BASE,\nwhich it does for a value under 1\u003c\u003c32.\n\nThis changes ptrace access to fs_base and gs_base to work like\nPTRACE_ARCH_PRCTL does. That is, it reads the base address that\nuser-mode memory access using the fs/gs instruction prefixes will\nuse, regardless of how it\u0027s being implemented in the kernel. The\nMSR vs GDT is an implementation detail that is pretty much hidden\nfrom userland in the actual using, and there is no reason that\nptrace should give the internal implementation picture rather than\nthe user-mode semantic picture. In the case of setting the value,\nthis can implicitly change the fsindex/gsindex value (also\nseparately in user_regs_struct), which is what happens when the\nthread calls arch_prctl itself. In a PTRACE_SETREGS, the fs_base\nchange will come after the fsindex change due to the order of the\nstruct, and so a change the debugger made to fs_base will have the\neffect intended, another part of the user_regs_struct will now\ndiffer when read back from what the debugger wrote.\n\nThis makes PTRACE_ARCH_PRCTL obsolete.

The new images use a linker\nscript sharing the layout parts from vdso-layout.lds.S with the 64-bit\nvDSO. A new vdso32-syms.lds is generated in the style of vdso-syms.lds.\n\nSigned-off-by: Roland McGrath \u003croland@redhat.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "0c2f51a7d2546f65e4198cccd6a56e2a8b857677", "tree": "6b2b39b317f4799faf64328353ba796ae8827ac5", "parents": [ "108b545137b03ec1d6a5765017d57f86056bf57c" ], "author": { "name": "Roland McGrath", "email": "roland@redhat.com", "time": "Wed Jan 30 13:30:42 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 30 13:30:42 2008 +0100" }, "message": "x86 vDSO: arch/x86/vdso/vdso32\n\nThis moves the i386 vDSO sources into arch/x86/vdso/vdso32/, a\nnew directory.
