This patch adds a .notify() method. The presence of .notify() causes Linux/ACPI to manage event handlers and notify handlers on our behalf, so we don't have to install and remove them ourselves. Note that events from fixed hardware buttons now show up as a special notify event, so to preserve user-space backward compatibility, we convert that back to ACPI_BUTTON_NOTIFY_STATUS.

This patch adds support for ACPI device driver .notify() methods. If such a method is present, Linux/ACPI installs a handler for device notifications (but not for system notifications such as Bus Check, Device Check, etc). When a device notification occurs, Linux/ACPI passes it on to the driver's .notify() method. In most cases, this removes the need for drivers to install their own handlers for device-specific notifications. For fixed hardware devices like some power and sleep buttons, there's no notification value because there's no control method to execute a Notify opcode. When a fixed hardware device generates an event, we handle it the same as a regular device notification, except we send a ACPI_FIXED_HARDWARE_EVENT value. This is outside the normal 0x0-0xff range used by Notify opcodes. Several drivers install their own handlers for system Bus Check and Device Check notifications so they can support hot-plug. This patch doesn't affect that usage. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Reviewed-by: Alex Chiang <achiang@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>

Linus Torvalds authored
Instead of always splitting the file offset into 32-bit 'high' and 'low' parts, just split them into the largest natural word-size - which in C terms is 'unsigned long'. This allows 64-bit architectures to avoid the unnecessary 32-bit shifting and masking for native format (while the compat interfaces will obviously always have to do it). This also changes the order of 'high' and 'low' to be "low first". Why? Because when we have it like this, the 64-bit system calls now don't use the "pos_high" argument at all, and it makes more sense for the native system call to simply match the user-mode prototype. This results in a much more natural calling convention, and allows the compiler to generate much more straightforward code. On x86-64, we now generate testq %rcx, %rcx # pos_l js .L122 #, movq %rcx, -48(%rbp) # pos_l, pos from the C source loff_t pos = pos_from_hilo(pos_h, pos_l); ... if (pos < 0) return -EINVAL; and the 'pos_h' register isn't even touched. It used to generate code like mov %r8d, %r8d # pos_low, pos_low salq $32, %rcx #, tmp71 movq %r8, %rax # pos_low, pos.386 orq %rcx, %rax # tmp71, pos.386 js .L122 #, movq %rax, -48(%rbp) # pos.386, pos which isn't _that_ horrible, but it does show how the natural word size is just a more sensible interface (same arguments will hold in the user level glibc wrapper function, of course, so the kernel side is just half of the equation!) Note: in all cases the user code wrapper can again be the same. You can just do #define HALF_BITS (sizeof(unsigned long)*4) __syscall(PWRITEV, fd, iov, count, offset, (offset >> HALF_BITS) >> HALF_BITS); or something like that. That way the user mode wrapper will also be nicely passing in a zero (it won't actually have to do the shifts, the compiler will understand what is going on) for the last argument. And that is a good idea, even if nobody will necessarily ever care: if we ever do move to a 128-bit lloff_t, this particular system call might be left alone. Of course, that will be the least of our worries if we really ever need to care, so this may not be worth really caring about.

The battery driver tends to take quite some time to initialize (100ms-300ms is quite typical). This patch initializes the batter driver asynchronously, so that other things in the kernel can initialize in parallel to this 300 msec. As part of this, the battery driver had to move to the back of the ACPI init order (hence the Makefile change). Without this move, the next ACPI driver would just block on the ACPI/devicee layer semaphores until the battery driver was done anyway, not gaining any boot time.
