Dedac.rst145 - CPU caches (L1 and L2)
155 For example, a cache could be composed of L1, L2 and L3 levels of cache.
156 Each CPU core would have its own L1 cache, while sharing L2 and maybe L3

176 the L1 and L2 directories would be "edac_device_block's"
/Linux-v5.15/Documentation/locking/
Dlockdep-design.rst22 dependency can be understood as lock order, where L1 -> L2 suggests that
23 a task is attempting to acquire L2 while holding L1. From lockdep's
24 perspective, the two locks (L1 and L2) are not necessarily related; that
145 <L1> -> <L2>
146 <L2> -> <L1>
521 L1 -> L2
523 , which means lockdep has seen L1 held before L2 held in the same context at runtime.
524 And in deadlock detection, we care whether we could get blocked on L2 with L1 held,
525 IOW, whether there is a locker L3 that L1 blocks L3 and L2 gets blocked by L3. So
526 we only care about 1) what L1 blocks and 2) what blocks L2. As a result, we can combine

105 | 3.2 R := R + N*L2, L2 := extended-precision(-log2/64 - L1).
106 | Notes: a) The way L1 and L2 are chosen ensures L1+L2 approximate
108 | b) N*L1 is exact because N is no longer than 22 bits and
109 | L1 is no longer than 24 bits.
110 | c) The calculation X+N*L1 is also exact due to cancellation.
