From 1a3cc1209b4ca541e3b8f4fd360704e071e1e7bc Mon Sep 17 00:00:00 2001 From: Frederic Barrat Date: Tue, 11 Mar 2025 11:53:52 +1000 Subject: ppc/xive2: Support crowd-matching when looking for target XIVE crowd sizes are encoded into a 2-bit field as follows: 0: 0b00 2: 0b01 4: 0b10 16: 0b11 A crowd size of 8 is not supported. If an END is defined with the 'crowd' bit set, then a target can be running on different blocks. It means that some bits from the block VP are masked when looking for a match. It is similar to groups, but on the block instead of the VP index. Most of the changes are due to passing the extra argument 'crowd' all the way to the function checking for matches.
