8b4b61f140 fs/cromfs: Fix a error in reading partial compressed blocks. The LZF decompressor does not support that operation. Instead we have to decompress full block into a temporary buffer and copy out the parts that we need. To compensate for the performance hit, a caching mechanism was added so that we do not have to read the same block repeatedly. Unrelated: Also updates some README files. 2018-03-24 11:30:35 -06:00

0f03ffc745 STM32, STM32L4: add one bit read and write to 1-wire interface. This is needed for devices that require single bit timeslot generation and for 1-Wire search algorithm triplets. 2018-03-23 08:07:20 -06:00

3810f9e942 Remove configurations using canutils/libuavcan and examples/uavcan. libuavcan has not built for a year or so. The basic problem is that as NuttX advances, the old frozen versino of libuavcan has become absolute because it violates the portable POSIX OS interface. No one is maintaining the port so there is no alternative but to remove it. 2018-03-23 07:37:49 -06:00

3ec02adee0 tools/genromfs.c: Improve check for empty directories. If the directory contains only unsupported, special files, then it is still empty. Fix some collection of statistics that was cause statfs() to return some incorrect values. Add logic to handle the case where the host and the target differ in endian-ness. fs/procfs: In show mountpoints, add support so that the CROMFS file system type is recognized. 2018-03-21 08:40:02 -06:00

22484386ee fs/cromfs and tools/gencromfs: Various fixes for traversal relative file paths. Biggest changes is in types used: Cannot use size_t or mode_t in common structures because they have different sizes on the (64-bit) host and the (32-bit) target. Use uint32_t instead of size_t for offsets. Use uint16_t instead of mode_t. 2018-03-20 12:37:01 -06:00

eec44d1f01 This commit adds tools/gencromfs.c, a tool that can be used to generate CROMFS file system images.
Squashed commit of the following:

    tools/gencromfs.c:  Seems basically functional but has not has not yet been integrated with CROMFS.
    tools/gencromfs.c:  Revist previous commit.  Let's make no assumptions about the compatibility of the host system and NuttX.
    tools/gencromfs.c:  I think access mode bits are sufficiently standard that we can just copy them from the host.  This is don't mostly to pick up the executable bits and other conbinations of bits without doing a bit-for-bit decode.
    tools/gencromfs.c:  Code complete but only partially functional.
    tools/gencromfs.c:  type definitions must precede data definitions
    tools/gencromfs.c:  Adds a little more logic to gencromfs tools.  Still not complete but can traverse directories and generate directory and hard-link nodes.
    tools/gencromfs.c: Beginning of a genromfs tool that will eventually be used for generation of CROMFS file system images.

Fix SMP related bugs

* sched/sched: Fix a deadlock in SMP mode

    Two months ago, I introduced sched_tasklist_lock() and
    sched_tasklist_unlock() to protect tasklists in SMP mode.
    Actually, this change works pretty well for HTTP audio
    streaming aging test with lc823450-xgevk.

    However, I found a deadlock in the scheduler when I tried
    similar aging tests with DVFS autonomous mode where CPU
    clock speed changed based on cpu load. In this case, call
    sequences were as follows;

    cpu1: sched_unlock()->sched_mergepending()->sched_addreadytorun()->up_cpu_pause()
    cpu0: sched_lock()->sched_mergepending()

    To avoid this deadlock, I added sched_tasklist_unlock() when calling
    up_cpu_pause() and sched_addreadytorun(). Also, added
    sched_tasklist_lock() after the call.

* libc: Add critical section in lib_filesem.c for SMP

    To set my_pid into fs_folder atomically in SMP mode,
    critical section API must be used.

0478b5bce4 Addes CROMFS prototype. CROMFS is a commpressed, in-memory read-only file system based on LZF.
Squashed commit of the following:

    fs/cromfs:  Now depends on EXPERIMENTAL because it is not yet verified.
    fs/cromfs:  This commit brings the CROMFS file system to code complete.  Still completely untested.  Next steps:  Need a tool to generate CROMFS file system images and a test case under apps/
    fs/cromfs:  Add logic to traverse the in-memory file system nodes.
    fs/cromfs:  Add initial support for an in-memory, compressed, read-only file system.
