All the ia64 pvops code is now dead code since both xen and kvm support have been ripped out [0] [1]. Just that no one had troubled to rip this stuff out. The only useful remaining pieces were the old pvops docs but that was recently also generalized and moved out from ia64 [2]. This has been run time tested on an ia64 Madison system. [0]003f7de625"KVM: ia64: remove" since v3.19-rc1 [1]d52eefb47d"ia64/xen: Remove Xen support for ia64" since v3.14-rc1 [2] "virtual: Documentation: simplify and generalize paravirt_ops.txt" Signed-off-by: Luis R.

/*
|
|
* We get here for syscalls that don't have a lightweight
|
|
* handler. For those, we need to bubble down into the kernel
|
|
* and that requires setting up a minimal pt_regs structure,
|
|
* and initializing the CPU state more or less as if an
|
|
* interruption had occurred. To make syscall-restarts work,
|
|
* we setup pt_regs such that cr_iip points to the second
|
|
* instruction in syscall_via_break. Decrementing the IP
|
|
* hence will restart the syscall via break and not
|
|
* decrementing IP will return us to the caller, as usual.
|
|
* Note that we preserve the value of psr.pp rather than
|
|
* initializing it from dcr.pp. This makes it possible to
|
|
* distinguish fsyscall execution from other privileged
|
|
* execution.
|
|
*
|
|
* On entry:
|
|
* - normal fsyscall handler register usage, except
|
|
* that we also have:
|
|
* - r18: address of syscall entry point
|
|
* - r21: ar.fpsr
|
|
* - r26: ar.pfs
|
|
* - r27: ar.rsc
|
|
* - r29: psr
|
|
*
|
|
* We used to clear some PSR bits here but that requires slow
|
|
* serialization. Fortuntely, that isn't really necessary.
|
|
* The rationale is as follows: we used to clear bits
|
|
* ~PSR_PRESERVED_BITS in PSR.L. Since
|
|
* PSR_PRESERVED_BITS==PSR.{UP,MFL,MFH,PK,DT,PP,SP,RT,IC}, we
|
|
* ended up clearing PSR.{BE,AC,I,DFL,DFH,DI,DB,SI,TB}.
|
|
* However,
|
|
*
|
|
* PSR.BE : already is turned off in __kernel_syscall_via_epc()
|
|
* PSR.AC : don't care (kernel normally turns PSR.AC on)
|
|
* PSR.I : already turned off by the time fsys_bubble_down gets
|
|
* invoked
|
|
* PSR.DFL: always 0 (kernel never turns it on)
|
|
* PSR.DFH: don't care --- kernel never touches f32-f127 on its own
|
|
* initiative
|
|
* PSR.DI : always 0 (kernel never turns it on)
|
|
* PSR.SI : always 0 (kernel never turns it on)
|
|
* PSR.DB : don't care --- kernel never enables kernel-level
|
|
* breakpoints
|
|
* PSR.TB : must be 0 already; if it wasn't zero on entry to
|
|
* __kernel_syscall_via_epc, the branch to fsys_bubble_down
|
|
* will trigger a taken branch; the taken-trap-handler then
|
|
* converts the syscall into a break-based system-call.
|
|
*/
|
|
/*
|
|
* Reading psr.l gives us only bits 0-31, psr.it, and psr.mc.
|
|
* The rest we have to synthesize.
