2009-06-12virtio_pci: optional MSI-X supportMichael S. Tsirkin
This implements optional MSI-X support in virtio_pci. MSI-X is used whenever the host supports at least 2 MSI-X vectors: 1 for configuration changes and 1 for virtqueues. Per-virtqueue vectors are allocated if enough vectors available. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (+ whitespace, style)
2009-06-12virtio_pci: split up vp_interruptMichael S. Tsirkin
This reorganizes virtio-pci code in vp_interrupt slightly, so that it's easier to add per-vq MSI support on top. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-06-12virtio: find_vqs/del_vqs virtio operationsMichael S. Tsirkin
This replaces find_vq/del_vq with find_vqs/del_vqs virtio operations, and updates all drivers. This is needed for MSI support, because MSI needs to know the total number of vectors upfront. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (+ lguest/9p compile fixes)
2009-06-12virtio: add names to virtqueue struct, mapping from devices to queues.Rusty Russell
Add a linked list of all virtqueues for a virtio device: this helps for debugging and is also needed for upcoming interface change. Also, add a "name" field for clearer debug messages. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-06-12virtio: meet virtio spec by finalizing features before using deviceRusty Russell
Virtio devices are supposed to negotiate features before they start using the device, but the current code doesn't do this. This is because the driver's probe() function invariably has to add buffers to a virtqueue, or probe the disk (virtio_blk). This currently doesn't matter since no existing backend is strict about the feature negotiation. But it's possible to imagine a future feature which completely changes how a device operates: in this case, we'd need to acknowledge it before using the device.

2009-06-12perf_counter: Add forward/backward attribute ABI compatibilityPeter Zijlstra
Provide for means of extending the perf_counter_attr in a 'natural' way. We allow growing the structure by appending fields at the end by specifying the full structure size inside it. When a new kernel sees a smaller (old) structure, it will 0 pad the tail. When an old kernel sees a larger (new) structure, it will verify the tail consists of 0s, otherwise fail. If we fail due to a size-mismatch, we return -E2BIG and write the kernel's native attribe size back into the provided structure. Furthermore, add some attribute verification, so that we'll fail counter creation when unknown bits are present (PERF_SAMPLE, PERF_FORMAT, or in the __reserved fields). (This ABI detail is introduced while keeping the existing syscall ABI.)

2009-06-12perf record: Explicity program a default counterPeter Zijlstra
Up until now record has worked on the assumption that type=0, config=0 was a suitable configuration - which it is.

2009-06-12module: cleanup FIXME comments about trimming exception table entries.Rusty Russell
Everyone cut and paste this comment from my original one. We now do it generically, so cut the comments. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Amerigo Wang <amwang@redhat.com>
2009-06-12module: trim exception table on init free.Rusty Russell
It's theoretically possible that there are exception table entries which point into the (freed) init text of modules. These could cause future problems if other modules get loaded into that memory and cause an exception as we'd see the wrong fixup. The only case I know of is kvm-intel.ko (when CONFIG_CC_OPTIMIZE_FOR_SIZE=n). Amerigo fixed this long-standing FIXME in the x86 version, but this patch is more general. This implements trim_init_extable(); most archs are simple since they use the standard lib/extable.c sort code. Alpha and IA64 use relative addresses in their fixups, so thier trimming is a slight variation. Sparc32 is unique; it doesn't seem to define ARCH_HAS_SORT_EXTABLE, yet it defines its own sort_extable() which overrides the one in lib. It doesn't sort, so we have to mark deleted entries instead of actually trimming them.

2009-06-12uvesafb: improve parameter handling.Rusty Russell
1) Now module_param(..., invbool, ...) requires a bool, and similarly module_param(..., bool, ...) allows it, change pmi_setpal to a bool. 2) #define param_get_scroll to NULL, since it can never be called (perm argument to module_param_named is 0). 3) Return -EINVAL from param_set_scroll if the value is bad, so it's reported. Note that I don't think the old fb_get_options() is required for new drivers: the parameters automatically work as uvesafb.XXX=... anyway.

2009-06-12module_param: allow 'bool' module_params to be bool, not just int.Rusty Russell
Impact: API cleanup For historical reasons, 'bool' parameters must be an int, not a bool. But there are around 600 users, so a conversion seems like useless churn. So we use __same_type() to distinguish, and handle both cases. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-06-12module_param: add __same_type convenience wrapper for ↵Rusty Russell
__builtin_types_compatible_p Impact: new API __builtin_types_compatible_p() is a little awkward to use: it takes two types rather than types or variables, and it's just damn long. (typeof(type) == type, so this works on types as well as vars). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-06-12module_param: split perm field into flags and permRusty Russell
Impact: cleanup Rather than hack KPARAM_KMALLOCED into the perm field, separate it out. Since the perm field was 32 bits and only needs 16, we don't add bloat. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-06-12module_param: invbool should take a 'bool', not an 'int'Rusty Russell
It takes an 'int' for historical reasons, and there are only two users: simply switch it over to bool. The other user (uvesafb.c) will get a (harmless-on-x86) warning until the next patch is applied.

The sparseirq changes (d7e51e66) played poorly with the Blackfin irqchip implementation as we're still using the old hardirq method.

2009-06-12Blackfin: push access_ok() L1 attribute downMike Frysinger
There is no need for the L1 attribute to be on the prototype of the access_ok() function as all consumers of the function do not care where it lives -- they'll always use pcrel calls to get to it.

2009-06-12Blackfin: override default uClinux MTD addr/sizeMike Frysinger
Due to a processor anomaly (05000263 to be exact), most Blackfin parts cannot keep the embedded filesystem image directly after the kernel in RAM.
