It can't go away between reserve and unreserve, and I think it also can't be evicted then. Havn't checked how ttm implements that. cheers, Gerd

Call reservation_object_* directly instead of using ttm_bo_{reserve,unreserve}. v4: check for EINTR only. v3: check for EINTR too.

On which versions of FreeBSD is it now possible to un-reserve ports? ( I've been waiting for this since forever ... have spent countless days - $$$ - trying to install workarounds, only to junk them later. I've even been paid a consulting gig to develop this, and declined to deploy it on my own servers :-/ ) iang

...t has particular uses and should be considered unavailable at all times. If it is unavailable at all times, why not make such a reserved register unallocatable? Thanks! Registers are partitioned into three disjoint sets: 1. Allocatable registers. 2. Reserved registers. 3. The rest: Unallocatable, unreserved registers. The set of reserved registers is not known to TableGen, and it can vary for different sub-targets, and even different functions. The reserved registers for a function are computed by the TRI::getReservedRegs(MF) hook. A register is allocatable if it belongs to at least one allocatabl...

Hi, I'm writing to ask the differences between a "reserved" register and an "unallocable" register. In X86 backend, for example, the stack pointer register and instruction pointer are reserved but allocatable. In the Doxygen document of function llvm::TargetRegisterInfo::getReservedRegs, it says that a reserved register is one that *has particular uses and should be
