2020-01-13dt-bindings: Create DT bindings for PATA controllersLinus Walleij1-0/+50
I need to create subnodes for drives connected to PATA host controllers, and this needs to be supported generally, so create a common YAML binding for "ide" that will support subnodes with ports. This has been designed as a subset of ata/ahci-platform.txt with the bare essentials and should be possible to extend or superset to cover the common bindings.

There used to be blank lines between assignment and check of the __of_changeset_revert_entries() result, to make the phandle cache management operations stand out. After the removal of those operations in commit 90dc0d1ce890419f ("of: Rework and simplify phandle cache to use a fixed size"), there is no longer a reason to have such a blank line. Remove the blank line, to rejoin visibly the status assignement and check, and to match coding style.

2019-12-24of: Rework and simplify phandle cache to use a fixed sizeRob Herring4-124/+24
The phandle cache was added to speed up of_find_node_by_phandle() by avoiding walking the whole DT to find a matching phandle. The implementation has several shortcomings: - The cache is designed to work on a linear set of phandle values. This is true for dtc generated DTs, but not for other cases such as Power. - The cache isn't enabled until of_core_init() and a typical system may see hundreds of calls to of_find_node_by_phandle() before that point. - The cache is freed and re-allocated when the number of phandles changes. - It takes a raw spinlock around a memory allocation which breaks on RT. Change the implementation to a fixed size and use hash_32() as the cache index. This greatly simplifies the implementation. It avoids the need for any re-alloc of the cache and taking a reference on nodes in the cache. We only have a single source of removing cache entries which is of_detach_node(). Using hash_32() removes any assumption on phandle values improving the hit rate for non-linear phandle values. The effect on linear values using hash_32() is about a 10% collision. The chances of thrashing on colliding values seems to be low. To compare performance, I used a RK3399 board which is a pretty typical system. I found that just measuring boot time as done previously is noisy and may be impacted by other things. Also bringing up secondary cores causes some issues with measuring, so I booted with 'nr_cpus=1'. With no caching, calls to of_find_node_by_phandle() take about 20124 us for 1248 calls. There's an additional 288 calls before time keeping is up. Using the average time per hit/miss with the cache, we can calculate these calls to take 690 us (277 hit / 11 miss) with a 128 entry cache and 13319 us with no cache or an uninitialized cache. Comparing the 3 implementations the time spent in of_find_node_by_phandle() is: no cache: 20124 us (+ 13319 us) 128 entry cache: 5134 us (+ 690 us) current cache: 819 us (+ 13319 us) We could move the allocation of the cache earlier to improve the current cache, but that just further complicates the situation as it needs to be after slab is up, so we can't do it when unflattening (which uses memblock).
