/* Sun4v hypervisor interfaces and defines.
|
|
*
|
|
* Hypervisor calls are made via traps to software traps number 0x80
|
|
* and above. Registers %o0 to %o5 serve as argument, status, and
|
|
* return value registers.
|
|
*
|
|
* There are two kinds of these traps. First there are the normal
|
|
* "fast traps" which use software trap 0x80 and encode the function
|
|
* to invoke by number in register %o5. Argument and return value
|
|
* handling is as follows:
|
|
*
|
|
* -----------------------------------------------
|
|
* | %o5 | function number | undefined |
|
|
* | %o0 | argument 0 | return status |
|
|
* | %o1 | argument 1 | return value 1 |
|
|
* | %o2 | argument 2 | return value 2 |
|
|
* | %o3 | argument 3 | return value 3 |
|
|
* | %o4 | argument 4 | return value 4 |
|
|
* -----------------------------------------------
|
|
*
|
|
* The second type are "hyper-fast traps" which encode the function
|
|
* number in the software trap number itself. So these use trap
|
|
* numbers > 0x80. The register usage for hyper-fast traps is as
|
|
* follows:
|
|
*
|
|
* -----------------------------------------------
|
|
* | %o0 | argument 0 | return status |
|
|
* | %o1 | argument 1 | return value 1 |
|
|
* | %o2 | argument 2 | return value 2 |
|
|
* | %o3 | argument 3 | return value 3 |
|
|
* | %o4 | argument 4 | return value 4 |
|
|
* -----------------------------------------------
|
|
*
|
|
* Registers providing explicit arguments to the hypervisor calls
|
|
* are volatile across the call. Upon return their values are
|
|
* undefined unless explicitly specified as containing a particular
|
|
* return value by the specific call. The return status is always
|
|
* returned in register %o0, zero indicates a successful execution of
|
|
* the hypervisor call and other values indicate an error status as
|
|
* defined below. So, for example, if a hyper-fast trap takes
|
|
* arguments 0, 1, and 2, then %o0, %o1, and %o2 are volatile across
|
|
* the call and %o3, %o4, and %o5 would be preserved.
|
|
*
|
|
* If the hypervisor trap is invalid, or the fast trap function number
|
|
* is invalid, HV_EBADTRAP will be returned in %o0. Also, all 64-bits
|
|
* of the argument and return values are significant.

|
|

|
|
* See the terminology descriptions in the device interrupt services
|
|
* section above as those apply here too. Here are terminology
|
|
* definitions specific to these PCI IO services:
|
|
*
|
|
* tsbnum TSB number. Indentifies which io-tsb is used.
|
|
* For this version of the specification, tsbnum
|
|
* must be zero.
|
|
*
|
|
* tsbindex TSB index. Identifies which entry in the TSB
|
|
* is used. The first entry is zero.
|
|
*
|
|
* tsbid A 64-bit aligned data structure which contains
|
|
* a tsbnum and a tsbindex. Bits 63:32 contain the
|
|
* tsbnum and bits 31:00 contain the tsbindex.
|
|
*
|
|
* Use the HV_PCI_TSBID() macro to construct such
|
|
* values.
|
|
*
|
|
* io_attributes IO attributes for IOMMU mappings. One of more
|
|
* of the attritbute bits are stores in a 64-bit
|
|
* value. The values are defined below.
|
|
*
|
|
* r_addr 64-bit real address
|
|
*
|
|
* pci_device PCI device address. A PCI device address identifies
|
|
* a specific device on a specific PCI bus segment.
|
|
* A PCI device address ia a 32-bit unsigned integer
|
|
* with the following format:
|
|
*
|
|
* 00000000.bbbbbbbb.dddddfff.00000000
|
|
*
|
|
* Use the HV_PCI_DEVICE_BUILD() macro to construct
|
|
* such values.
|
|
*
|
|
* pci_config_offset
|
|
* PCI configureation space offset. For conventional
|
|
* PCI a value between 0 and 255. For extended
|
|
* configuration space, a value between 0 and 4095.
|
|
*
|
|
* Note: For PCI configuration space accesses, the offset
|
|
* must be aligned to the access size.
|
|
*
|
|
* error_flag A return value which specifies if the action succeeded
|
|
* or failed. 0 means no error, non-0 means some error
|
|
* occurred while performing the service.
|
|
*
|
|
* io_sync_direction
|
|
* Direction definition for pci_dma_sync(), defined
|
|
* below in HV_PCI_SYNC_*.
|
|
*
|
|
* io_page_list A list of io_page_addresses, an io_page_address is
|
|
* a real address.
|
|
*
|
|
* io_page_list_p A pointer to an io_page_list.
|
|
*
|
|
* "size based byte swap" - Some functions do size based byte swapping
|
|
* which allows sw to access pointers and
|
|
* counters in native form when the processor
|
|
* operates in a different endianness than the
|
|
* IO bus. Size-based byte swapping converts a
|
|
* multi-byte field between big-endian and
|
|
* little-endian format.
