Booting a snapshot of Linus' tree this morning I saw a few (new?) kernel unaligned access warnings:
ACPI: Subsystem revision 20060127 ACPI: Interpreter enabled ACPI: Using IOSAPIC for interrupt routing ACPI: PCI Root Bridge [PCI0] (0000:00) kernel unaligned access to 0xe00000407ec5a204, ip=0xa0000001003af8c0 kernel unaligned access to 0xe00000407ec5a23c, ip=0xa0000001003af8c0 kernel unaligned access to 0xe00000407ec5a28c, ip=0xa0000001003af8c0 kernel unaligned access to 0xe00000407ec5a1fc, ip=0xa0000001003ae6c1 kernel unaligned access to 0xe00000407ec5a204, ip=0xa0000001003ae6d1 ACPI: PCI Interrupt Routing Table [\_SB_.SBA0.PCI0._PRT] ACPI: PCI Root Bridge [PCI1] (0000:20) The first three at ip=0xa0000001003af8c0 are in acpi_rs_get_resource_source() while zeroing a 64-bit value: a0000001003af8c0: dc 00 00 46 98 11 [MFB] (p06) st8 [r35]=r0 Which looks from the assembly code like we are doing a: resource_source->string_ptr = 0; but I don't see anything quite like that in the C source (but there may be macros & inlining happening). The other two, ip=0xa0000001003ae6c1 and ip=0xa0000001003ae6d1 are in acpi_resource_to_address64() close together in this little block: a0000001003ae6c6: 50 02 58 30 20 00 ld8 r37=[r22] a0000001003ae6cc: 00 00 00 20 nop.b 0x0;; a0000001003ae6d0: 19 00 94 1e 98 11 [MMB] st8 [r15]=r37 a0000001003ae6d6: 70 02 40 30 20 00 ld8 r39=[r16] These loads are dereferencing the acpi_resource structure that was passed as the first argument (offsets 40 and 48 bytes). -Tony - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
