add hierarchical bitmap data type and test cases HBitmaps provides an array of bits. The bits are stored as usual in an array of unsigned longs, but HBitmap is also optimized to provide fast iteration over set bits; going from one bit to the next is O(logB n) worst case, with B = sizeof(long) * CHAR_BIT: the result is low enough that the number of levels is in fact fixed. In order to do this, it stacks multiple bitmaps with progressively coarser granularity; in all levels except the last, bit N is set iff the N-th unsigned long is nonzero in the immediately next level. When iteration completes on the last level it can examine the 2nd-last level to quickly skip entire words, and even do so recursively to skip blocks of 64 words or powers thereof (32 on 32-bit machines). Given an index in the bitmap, it can be split in group of bits like this (for the 64-bit case): bits 0-57 => word in the last bitmap | bits 58-63 => bit in the word bits 0-51 => word in the 2nd-last bitmap | bits 52-57 => bit in the word bits 0-45 => word in the 3rd-last bitmap | bits 46-51 => bit in the word So it is easy to move up simply by shifting the index right by log2(BITS_PER_LONG) bits. To move down, you shift the index left similarly, and add the word index within the group. Iteration uses ffs (find first set bit) to find the next word to examine; this operation can be done in constant time in most current architectures. Setting or clearing a range of m bits on all levels, the work to perform is O(m + m/W + m/W^2 + ...), which is O(m) like on a regular bitmap. When iterating on a bitmap, each bit (on any level) is only visited once. Hence, The total cost of visiting a bitmap with m bits in it is the number of bits that are set in all bitmaps. Unless the bitmap is extremely sparse, this is also O(m + m/W + m/W^2 + ...), so the amortized cost of advancing from one bit to the next is usually constant.

keyval: New keyval_parse() keyval_parse() parses KEY=VALUE,... into a QDict. Works like qemu_opts_parse(), except: * Returns a QDict instead of a QemuOpts (d'oh). * Supports nesting, unlike QemuOpts: a KEY is split into key fragments at '.' (dotted key convention; the block layer does something similar on top of QemuOpts). The key fragments are QDict keys, and the last one's value is updated to VALUE. * Each key fragment may be up to 127 bytes long. qemu_opts_parse() limits the entire key to 127 bytes. * Overlong key fragments are rejected. qemu_opts_parse() silently truncates them. * Empty key fragments are rejected. qemu_opts_parse() happily accepts empty keys. * It does not store the returned value. qemu_opts_parse() stores it in the QemuOptsList. * It does not treat parameter "id" specially. qemu_opts_parse() ignores all but the first "id", and fails when its value isn't id_wellformed(), or duplicate (a QemuOpts with the same ID is already stored). It also screws up when a value contains ",id=". * Implied value is not supported. qemu_opts_parse() desugars "foo" to "foo=on", and "nofoo" to "foo=off". * An implied key's value can't be empty, and can't contain ','. I intend to grow this into a saner replacement for QemuOpts. It'll take time, though. Note: keyval_parse() provides no way to do lists, and its key syntax is incompatible with the __RFQDN_ prefix convention for downstream extensions, because it blindly splits at '.', even in __RFQDN_. Both issues will be addressed later in the series. Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <1488317230-26248-4-git-send-email-armbru@redhat.com>
