Subject: [PATCH -perfbook] future/htm: Remove ref to Tabel 17.3 in QQ
Date: Fri, 2 Jul 2021 10:52:21 +0900 [thread overview]
Message-ID: <27d3f40f-e51f-7f92-1bfa-e64149a55b37@gmail.com> (raw)
Table 17.3 is not available in EBook-size builds.
For compatibility, remove reference to the combined table in Quick
Quiz added in commit 279c38a988f9 ("future/htm: Add some HTM
hardware-reliability anecdotes").
Fixes: 279c38a988f9 ("future/htm: Add some HTM hardware-reliability anecdotes")

Hi Paul,
Current master fails to build "eb".
I think reference to Table 17.3 is not essential to the Quick Quiz
and just removed it.
If you think otherwise, it can be made conditional by \IfEbookSize{}{}.
Thanks, Akira
PS: As for hardware implementation of transactional memory,
Power ISA v3.1 deprecated it [1].
It might be worth mentioning it in the Answer to the QQ.
In the post specter world, it looks like almost impossible for hardware
designers to come up with a secure implementation of HTM...

state that hardware is only starting to become available.
But hasn't HTM hardware support been widely available
for almost a full decade?
