* disk: Return the partition number in part_get_info_by_name()Alex Deymo2017-05-111-1/+1
| | | | | | | | | | Similar to what blk_get_device_part_str() does, this patch makes part_get_info_by_name() return the partition number in case of a match. This is useful when the partition number is needed and not just the descriptor. Signed-off-by: Alex Deymo <deymo@google.com> Reviewed-by: Simon Glass <sjg@chromium.org>

* part_efi: support padding between the GPT header and partition entriesPhilipp Tomsich2017-03-202-4/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | Some architectures require their SPL loader at a fixed address within the first 16KB of the disk. To avoid an overlap with the partition entries of the EFI partition table, the first safe offset (in bytes, from the start of the device) for the entries can be set through CONFIG_EFI_PARTITION_ENTRIES_OFF (via Kconfig) When formatting a device with an EFI partition table, we may need to leave a gap between the GPT header (always in LBA 1) and the partition entries. The GPT header already contains a field to specify the on-disk location, which has so far always been set to LBA 2. With this change, a configurable offset will be translated into a LBA address indicating where to put the entries. Now also allows an override via device-tree using a config-node (see doc/device-tree-bindings/config.txt for documentation). Tested (exporting an internal MMC formatted with this) against Linux, MacOS X and Windows.

* drivers: block: add block device cacheEric Nelson2016-04-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a block device cache to speed up repeated reads of block devices by various filesystems. This small amount of cache can dramatically speed up filesystem operations by skipping repeated reads of common areas of a block device (typically directory structures). This has shown to have some benefit on FAT filesystem operations of loading a kernel and RAM disk, but more dramatic benefits on ext4 filesystems when the kernel and/or RAM disk are spread across multiple extent header structures as described in commit fc0fc50. The cache is implemented through a minimal list (block_cache) maintained in most-recently-used order and count of the current number of entries (cache_count). It uses a maximum block count setting to prevent copies of large block reads and an upper bound on the number of cached areas. The maximum number of entries in the cache defaults to 32 and the maximum number of blocks per cache entry has a default of 2, which has shown to produce the best results on testing of ext4 and FAT filesystems. The 'blkcache' command (enabled through CONFIG_CMD_BLOCK_CACHE) allows changing these values and can be used to tune for a particular filesystem layout. Signed-off-by: Eric Nelson <eric@nelint.com>

| | | | | | | | | | | | | | | | | | | We can use linker lists instead of explicitly declaring each function. This makes the code shorter by avoiding switch() statements and lots of header file declarations. While this does clean up the code it introduces a few code issues with SPL. SPL never needs to print partition information since this all happens from commands. SPL mostly doesn't need to obtain information about a partition either, except in a few cases. Add these cases so that the code will be dropped from each partition driver when not needed. This avoids code bloat. I think this is still a win, since it is not a bad thing to be explicit about which features are used in SPL. But others may like to weigh in.
