[SPARC64]: Fill holes in hypervisor APIs and fix KTSB registry.
Several interfaces were missing and others misnumbered or improperly documented. Also, make sure to check the return value when registering the kernel TSBs with the hypervisor. This helped to find the 4MB kernel TSB alignment bug fixed in a previous changeset. Signed-off-by: David S. Miller <davem@davemloft.net>

|
||||
* A guest uses this API to set a watchdog timer. Once the gues has set
|
||||
* the timer, it must call the timer service again either to disable or
|
||||
* postpone the expiration. If the timer expires before being reset or
|
||||
* disabled, then the hypervisor take a platform specific action leading
|
||||
* to guest termination within a bounded time period. The platform action
|
||||
* may include recovery actions such as reporting the expiration to a
|
||||
* Service Processor, and/or automatically restarting the gues.
|
||||
*
|
||||
* The 'timeout' parameter is specified in milliseconds, however the
|
||||
* implementated granularity is given by the 'watchdog-resolution'
|
||||
* property in the 'platform' node of the guest's machine description.
|
||||
* The largest allowed timeout value is specified by the
|
||||
* 'watchdog-max-timeout' property of the 'platform' node.
|
||||
*
|
||||
* If the 'timeout' argument is not zero, the watchdog timer is set to
|
||||
* expire after a minimum of 'timeout' milliseconds.
|
||||
*
|
||||
* If the 'timeout' argument is zero, the watchdog timer is disabled.
|
||||
*
|
||||
* If the 'timeout' value exceeds the value of the 'max-watchdog-timeout'
|
||||
* property, the hypervisor leaves the watchdog timer state unchanged,
|
||||
* and returns a status of EINVAL.
|
||||
*
|
||||
* The 'time remaining' return value is valid regardless of whether the
|
||||
* return status is EOK or EINVAL. A non-zero return value indicates the
|
||||
* number of milliseconds that were remaining until the timer was to expire.
|
||||
* If less than one millisecond remains, the return value is '1'. If the
|
||||
* watchdog timer was disabled at the time of the call, the return value is
|
||||
* zero.
|
||||
*
|
||||
* If the hypervisor cannot support the exact timeout value requested, but
|
||||
* can support a larger timeout value, the hypervisor may round the actual
|
||||
* timeout to a value larger than the requested timeout, consequently the
|
||||
* 'time remaining' return value may be larger than the previously requested
|
||||
* timeout value.
|
||||
*
|
||||
* Any guest OS debugger should be aware that the watchdog service may be in
|
||||
* use. Consequently, it is recommended that the watchdog service is
|
||||
* disabled upon debugger entry (e.g. reaching a breakpoint), and then
|
||||
* re-enabled upon returning to normal execution. The API has been designed
|
||||
* with this in mind, and the 'time remaining' result of the disable call may
|
||||
* be used directly as the timeout argument of the re-enable call.

* given channel ID, to be placed at the given real address, and
|
||||
* be of the given num entries. Num entries must be a power of two.
|
||||
* The real address base of the queue must be aligned on the queue
|
||||
* size. Each queue entry is 64-bytes, so for example, a 32 entry
|
||||
* queue must be aligned on a 2048 byte real address boundary.
|
||||
*
|
||||
* The endpoint's transmit queue is un-configured if num entries is zero.
|
||||
*
|
||||
* If a valid receive queue is specified for a local endpoint the LDC is
|
||||
* in the up state for the purpose of transmission to this endpoint.
|
||||
*
|
||||
* The maximum number of entries for each queue for a specific cpu may be
|
||||
* determined from the machine description.
|
||||
*
|
||||
* As receive queue configuration causes a reset of the queue's head and
|
||||
* tail pointers there is no way for a gues to determine how many entries
|
||||
* have been received between a preceeding ldc_get_rx_state() API call
|
||||
* and the completion of the configuration operation. It should be noted
|
||||
* that datagram delivery is not guarenteed via domain channels anyway,
|
||||
* and therefore any higher protocol should be resilient to datagram
|
||||
* loss if necessary. However, to overcome this specific race potential
|
||||
* it is recommended, for example, that a higher level protocol be employed
|
||||
* to ensure either retransmission, or ensure that no datagrams are pending
|
||||
* on the peer endpoint's transmit queue prior to the configuration process.
