§
unimplemented_physical_address(paddr) Return TRUE if the presented physical address is unimplemented on this processor
model; FALSE otherwise. This function is model specific.
unimplemented_virtual_address(vaddr,
vm) Return TRUE if the presented virtual address is unimplemented on this processor
model; FALSE otherwise. If vm is 1, one additional bit of virtual address is treated as
unimplemented. This function is model specific.
vm_all_probes() Returns TRUE if the processor is configured to virtualize all probe instructions when
PSR.vm is 1. See
Section 11.7.4.2.8, “Probe Instruction Virtualization” on
page 2:344 for details.
vm_disabled() Returns TRUE if the processor implements the PSR.vm bit and virtual machine
features are disabled. See
Section 3.4, “Processor Virtualization” on page 2:44 in
SDM and “PAL_PROC_GET_FEATURES – Get Processor Dependent Features
(17)” on page 2:446 in SDM for details.
vm_select_probes() Returns TRUE if the processor is configured to virtualize selected probe instructions
when PSR.vm is 1. See
Section 11.7.4.2.8, “Probe Instruction Virtualization” on
page 2:344 for details.
vmsw_disabled() Returns TRUE if the processor implements the PSR.vm bit and the
vmsw
instruction
is disabled. See Section 3.4, “Processor Virtualization” on page 2:44 in SDM and
“PAL_PROC_GET_FEATURES – Get Processor Dependent Features (17)” on
page 2:446 in SDM
for details.
zero_ext(value, pos) Returns a 64 bit unsigned number with bits
pos
-1 through 0 taken from
value
and
zeroes in bit positions
pos
through 63. If
pos
is greater than or equal to 64,
value
is
returned.
