2007-10-24x86: clean up setup.h and the boot codeH. Peter Anvin1-6/+7
Make <asm/setup.h> usable by the boot code. Clean up vestiges of the old command-line protocol from setup.h and head_32.S (it is still supported from the boot loader point of view, since it is converted to the new command-line protocol by the boot code.)

2007-10-24x86: lock bitopsNick Piggin2-2/+83
I missed an obvious one! x86 CPUs are defined not to reorder stores past earlier loads, so there is no hardware memory barrier required to implement a release-consistent store (all stores are, by definition). So ditch the generic lock bitops, and implement optimised versions for x86, which removes the mfence from __clear_bit_unlock (which is already a useful primitive for SLUB).

Commits 58b053e4ce9d2fc3023645c1b96e537c72aa8d9a ("Update arch/ to use sg helpers") 45711f1af6eff1a6d010703b4862e0d2b9afd056 ("[SG] Update drivers to use sg helpers") fa05f1286be25a8ce915c5dd492aea61126b3f33 ("Update net/ to use sg helpers") converted many files to use the scatter gather helpers without ensuring that the necessary headerfile <linux/scatterlist> is included. This happened to work for ia64, powerpc, sparc64 and x86 because they happened to drag in that file via their <asm/dma-mapping.h>. On most of the others this probably broke. Instead of increasing the header file spider web I choose to include <linux/scatterlist.h> directly into the affectes files.

2007-10-23[AVR32] Implement at32_add_device_cf()Haavard Skinnemoen1-0/+11
Implement at32_add_device_cf() which will add a platform_device for the at32_cf driver (not merged yet). Separate out most of the at32_add_device_ide() code and use it to implement at32_add_device_cf() as well. This changes the API in the following ways: * The board code must initialize data->cs to the chipselect ID to use before calling any of these functions. * The board code must use GPIO_PIN_NONE to indicate unused CF pins.

Implement functions for adding platform devices for TWI, MCI, AC97C and ABDAC. They may need to be modified to cope with platform data, etc. when the corresponding drivers are ready to be merged, but such changes are much less likely to conflict than adding support for a whole new type of device.

2007-10-23Lguest support for VirtioRusty Russell1-28/+19
This makes lguest able to use the virtio devices. We change the device descriptor page from a simple array to a variable length "type, config_len, status, config data..." format, and implement virtio_config_ops to read from that config data. We use the virtio ring implementation for an efficient Guest <-> Host virtqueue mechanism, and the new LHCALL_NOTIFY hypercall to kick the host when it changes. We also use LHCALL_NOTIFY on kernel addresses for very very early console output. We could have another hypercall, but this hack works quite well. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2007-10-23Remove old lguest I/O infrrasructure.Rusty Russell2-37/+2
This patch gets rid of the old lguest host I/O infrastructure and replaces it with a single hypercall "LHCALL_NOTIFY" which takes an address. The main change is the removal of io.c: that mainly did inter-guest I/O, which virtio doesn't yet support. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2007-10-23Remove old lguest bus and drivers.Rusty Russell2-77/+0
This gets rid of the lguest bus, drivers and DMA mechanism, to make way for a generic virtio mechanism. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2007-10-23Virtio helper routines for a descriptor ringbuffer implementationRusty Russell1-0/+119
These helper routines supply most of the virtqueue_ops for hypervisors which want to use a ring for virtio. Unlike the previous lguest implementation: 1) The rings are variable sized (2^n-1 elements). 2) They have an unfortunate limit of 65535 bytes per sg element. 3) The page numbers are always 64 bit (PAE anyone?) 4) They no longer place used[] on a separate page, just a separate cacheline. 5) We do a modulo on a variable. We could be tricky if we cared. 6) Interrupts and notifies are suppressed using flags within the rings. Users need only get the ring pages and provide a notify hook (KVM wants the guest to allocate the rings, lguest does it sanely).

2007-10-23Virtio console driverRusty Russell1-0/+12
This is an hvc-based virtio console driver. It's suboptimal becuase hvc expects to have raw access to interrupts and virtio doesn't assume that, so it currently polls. There are two solutions: expose hvc's "kick" interface, or wean off hvc. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
