Re: Status of 2.5.X kernels on PPC Linux, anyone working with NPTL?

Hi David,

Thanks for responding.

	There still is a question of what the final version of thread
support will look like in Glibc.  TLS support has not been added to
PowerPC GCC yet.  GPR 13 is reserved for the thread ID.  I do not know
whether that also can be used as the TLS base pointer.

Is IBM's NGPT the alternative being considered or just changes in how
NPTL is being implemented?

I did not realize that two registers were needed (a thread id register
and a tls base pointer).
Are you and Geoff the people that will make the decision of which
registers will be allocated and when?

Thanks,

Kevin
