>What about the other architectures? S390 could make use of one of the access registers. We do not use access registers for user programs at the moment (and probably never will). Its normal use is for concurrent access to multiple address spaces. We only use these registers in the kernel to copy between user and kernel address space. Access register 0 is unused anywhere so we could just use this one. We can't address data directly with this register but we can load it to a normal register in one cycle. I will take a look at the pthread implementation and give it a try. blue skies, Martin Linux/390 Design & Development, IBM Deutschland Entwicklung GmbH Schönaicherstr. 220, D-71032 Böblingen, Telefon: 49 - (0)7031 - 16-2247 E-Mail: schwidefsky@de.ibm.com
