* pcmcia: merge ds_internal.h into cs_internal.hDominik Brodowski2008-08-255-32/+40
| | | | | | Merge ds_internal.c into cs_internal.h. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: cleanup cs_internal.hDominik Brodowski2008-08-251-64/+90
| | | | | | Small cleanup to cs_internal.h. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: cs_internal.h is internalDominik Brodowski2008-08-255-5/+0
| | | | | | | cs_internal.h is meant for definitions internal to the PCMCIA core modules. It must not be included by PCMCIA socket drivers or by PCMCIA device drivers. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: use dev_printk for cs_error()Dominik Brodowski2008-08-232-33/+30
| | | | | | | | Use dev_printk() in cs_error()-based error reporting. While this function-turned-macro will hopefully go away soon, using dev_printk simplifies the code much. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: remove CS_ error codes alltogetherDominik Brodowski2008-08-232-33/+3
| | | | | | | | | | | Remoe the CS_ error codes. Drivers are expected to use default error definitions (errno.h etc.). Only one CS_ error code -- CS_IN_USE -- is used internally by the (deprecated) pcmcia-cs userspace package. Therefore, keep this one around so that it still compiles.

* pcmcia: deprecate CS_BAD_TUPLEDominik Brodowski2008-08-235-56/+99
| | | | | | | CS_BAD_TUPLE was used to denote a bad tuple being passed to the parse function. Therefore, replace it with -EINVAL and a verbose message. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: deprecate CS_BAD_ARGSDominik Brodowski2008-08-234-11/+12
| | | | | | | CS_BAD_ARGS mean a badly written driver or invalid userspace ioctl access, so translate that to -EINVAL. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: deprecate CS_BAD_BASE, CS_BAD_IRQ, CS_BAD_OFFSET and CS_BAD_SIZEDominik Brodowski2008-08-234-19/+22
| | | | | | | These four error values mostly mean a badly written driver, so ds_dbg() output and -EINVAL seems to be enough. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: deprecate CS_BAD_ATTRIBUTE, CS_BAD_TYPE and CS_BAD_PAGEDominik Brodowski2008-08-235-30/+37
| | | | | | | | | | | CS_BAD_TYPE was only used in cs.c and already properly annotated by error messages. CS_BAD_ATTRIBUTE and CS_BAD_PAGE mean a badly written driver, so ds_dbg() output and -EINVAL seems to be enough.

* pcmcia: deprecate CS_NO_MORE_ITEMSDominik Brodowski2008-08-237-11/+11
| | | | | | | | | | | | CS_NO_MORE_ITEMS is returned by the CIS tuple reading and parsing code if the end of a tuple chain is reached. As at least one PCMCIA driver relies on matching this return value, replace it with -ENOSPC which is now uniquely used for this purpose within the in-kernel pcmcia subsystem.

| | | | | | | | If a resource is already in use, mark it with -EBUSY. Same for cards already asleep. (includes a fix for a bug found by Larry Finger -- thanks!) Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: deprecate CS_CONFIGURATION_LOCKEDDominik Brodowski2008-08-233-8/+8
| | | | | | | This error code meant that trying to change the configuration after the initialization phase is forbidden. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: deprecate CS_BAD_HANDLEDominik Brodowski2008-08-234-12/+11
| | | | | | | | CS_BAD_HANDLE means that something went badly wrong: no parameter was passed, or the paramater passed wasn't the correct one. Therefore, replace it with -EINVAL. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: deprecate CS_GENERAL_FAILUREDominik Brodowski2008-08-233-4/+3
| | | | | | It's only used by pcmcia_core when socket-related queries time out. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: deprecate CS_NO_CARDDominik Brodowski2008-08-236-21/+21
| | | | | | It means that no card can be detected in the socket, so return -ENODEV Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: deprecate CS_BAD_VCC and CS_BAD_VPPDominik Brodowski2008-08-233-13/+23
| | | | | | | They were either used to report that changing voltage is not allowed, or that changing voltage failed. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: deprecate CS_UNSUPPORTED_*Dominik Brodowski2008-08-236-13/+14
| | | | | | | CS_UNSUPPORTED_MODE and CS_UNSUPPORTED_FUNCTION were mostly used to denote trying to use PCMCIA functions on CardBus cards. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: deprecate CS_OUT_OF_RESOURCEDominik Brodowski2008-08-235-33/+50

* pcmcia: deprecate unused CS_ error codesDominik Brodowski2008-08-232-20/+10
| | | | | | | Deprecate unused CS_ error codes by replacing their definitions with generic error messages, and removing them from the error_t lookup table. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: deprecate CS_SUCCESSDominik Brodowski2008-08-2335-212/+233
| | | | | | | | | Instead of using own error or success codes, the PCMCIA code should rely on the generic return values. Therefore, replace all occurrences of CS_SUCCESS with 0. CC: netdev@vger.kernel.org Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | lguest uses a Waker process to break it out of the kernel (ie. actually running the guest) when file descriptor needs attention. Changing this from a process to a thread somewhat simplifies things: it can directly access the fd_set of things to watch. More importantly, it means that the Waker can see Guest memory correctly, so /dev/vring file descriptors will work as anticipated (the alternative is to actually mmap MAP_SHARED, but you can't do that with /dev/zero).

| | | | | | | | | | | | | | | | | | | | | | | | Since the correct timeout value varies, use a heuristic which adjusts the timeout depending on how many packets we've seen.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | virtio_ring has the ability to suppress notifications. This prevents a guest exit for every packet, but we need to set a timer on packet receipt to re-check if there were any remaining packets.
