2006-10-14ACPI: acpi_pci_link_set() can allocate with either GFP_ATOMIC or GFP_KERNELJiri Kosina
acpi_pci_link_set() allocates both with interrupts on and with interrupts off (resume-time), so check interrupts and decide on GFP_ATOMIC or GFP_KERNEL at run-time. Signed-off-by: Jiri Kosina <jikos@jikos.cz> Signed-off-by: Len Brown <len.brown@intel.com>
2006-07-10ACPI: acpi_os_allocate() fixesLen Brown
Replace acpi_in_resume with a more general hack to check irqs_disabled() on any kmalloc() from ACPI. While setting (system_state != SYSTEM_RUNNING) on resume seemed more general, Andrew Morton preferred this approach. http://bugzilla.kernel.org/show_bug.cgi?id=3469 Make acpi_os_allocate() into an inline function to allow /proc/slab_allocators to work. Delete some memset() that could fault on allocation failure. Signed-off-by: Len Brown <len.brown@intel.com>

2005-12-12[PATCH] ACPI: fix sleeping whilst atomic warnings on resumeDave Jones
This has been broken for months. On resume, we call acpi_pci_link_set() with interrupts off, so we get a warning when we try to do a kmalloc of non atomic memory. The actual allocation is just 2 long's (plus extra byte for some reason I can't fathom), so a simple conversion to GFP_ATOMIC is probably the safest way to fix this. The error looks like this.. Debug: sleeping function called from invalid context at mm/slab.c:2486 in_atomic():0, irqs_disabled():1 [<c0143f6c>] kmem_cache_alloc+0x40/0x56 [<c0206a2e>] acpi_pci_link_set+0x3f/0x17f [<c0206f96>] irqrouter_resume+0x1e/0x3c [<c0239bca>] __sysdev_resume+0x11/0x6b [<c0239e88>] sysdev_resume+0x34/0x52 [<c023de21>] device_power_up+0x5/0xa Signed-off-by: Dave Jones <davej@redhat.com> Cc: "Brown, Len" <len.brown@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-12-10[ACPI] ACPICA 20050930Bob Moore
Completed a major overhaul of the Resource Manager code - specifically, optimizations in the area of the AML/internal resource conversion code. The code has been optimized to simplify and eliminate duplicated code, CPU stack use has been decreased by optimizing function parameters and local variables, and naming conventions across the manager have been standardized for clarity and ease of maintenance (this includes function, parameter, variable, and struct/typedef names.) All Resource Manager dispatch and information tables have been moved to a single location for clarity and ease of maintenance. One new file was created, named "rsinfo.c". The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to guarantee that the argument is not evaluated twice, making them less prone to macro side-effects. However, since there exists the possibility of additional stack use if a particular compiler cannot optimize them (such as in the debug generation case), the original macros are optionally available. Note that some invocations of the return_VALUE macro may now cause size mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to eliminate these. (From Randy Dunlap) Implemented a new mechanism to enable debug tracing for individual control methods. A new external interface, acpi_debug_trace(), is provided to enable this mechanism. The intent is to allow the host OS to easily enable and disable tracing for problematic control methods. This interface can be easily exposed to a user or debugger interface if desired. See the file psxface.c for details. acpi_ut_callocate() will now return a valid pointer if a length of zero is specified - a length of one is used and a warning is issued. This matches the behavior of acpi_ut_allocate(). Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2005-08-01Revert ACPI interrupt resume changesLinus Torvalds
If there are devices that use interrupts over a suspend event, ACPI must restore the PCI interrupt links on resume. Anything else breaks any device that hasn't been converted to the new (dubious) PM rules. Drivers that need the irq free/re-aquire sequence can be done one by one independently of this one.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
