dc8c814ca3 Squashed commit of the following:
Fixed coding standard error in several files.  Use of while( is incorrect; a space is required between while and (.  Also ran tools/nxstyle and fix thoses complaints as well in most files.

    Changes to comply with coding standard.  Mostly focused on files with missing space after keyword in if(, switch(, and for(.  Offending files also got changes to comply with tools nxstyle.  If there were logs of nxstyle complaints, the file also got a taste of tools/indent.sh.  Still need to fix occurrences of while( with missing space.  There are a lot of them.

91eb792e56 Corrections for the i.MXRT Ethernet:
(1) Now the Ethernet is completely re-initialized when an error occurs by means of taking the interface down and back up but the PHY is _not_ renegotiated for that case because that is very time consuming and an error in the Ethernet is no reflection on the state of the PHY anyway.

(2) Explicitly sets the expected PHY address to zero (this could be moved into the config) rather than searching for it which takes ages, and it's zero anyway for this board (that's the broadcast address, and anything that cannot respond on that has multiple PHYs, so that would be a new board).

(3) Allows for the renegotiation of the PHY to be optional when a reset is needed. If a non-renegotiated reset doesn't result in good comms to the PHY then it'll automatically be escalated to a renegotiated one.

(4) Only performs a reset for errors that need it (the CRITICAL_ERROR define).  The list of errors that need reset are somewhat arbitrarily chosen based on my prejudices and might need to be revisited, but certainly the jabber errors don't need reset, the partial packet is thrown away by the layer above anyway.

(5) Re-loads the multicast table on reset.

(6) Adds a bit more logging into the imxrt Ethernet module.

Pull request for mtd/progmem refactoring.

* mtd/progmem: change up_progmem_npages to up_progmem_neraseblocks

    page is a unit for read/write operation.
    eraseblock is a unit for erase operation.
    up_progmem_npages is a little bit confusing because it returns number of
    erase blocks in flash memory. This patch changes up_progmem_npages to
    up_progmem_neraseblocks. There is no logical change.

bc40403516 There was a reference counting problem in the TPC logic of net_clone(). net_clone() which is the common logic underlying dup() and dup2() for sockets. When net_clone() calls net_start_monitor() and net_start_monitor() returns a failure (because the underlying TCP connection) then net_clone() must back out the reference count on the structure. Problem noted by Pascal Speck and this implementation of the solution is based on his suggestion. 2017-10-19 11:09:23 -06:00

5ef548677a drivrs/mtd/filemtd.c: add block device MTD interface. Block MTD interface allows using block device directly as MTD instead of having to use file-system in between. NOTE that this provides the opposite capability of FTL which will let you use an MTD interface directly as a block device. 2017-10-19 09:53:41 -06:00

936df1bcb5 Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These differ from the standard sleep() and usleep() in that (1) they don't cause cancellation points, and (2) don't set the errno variable (if applicable). All calls to sleep() and usleep() changed to calls to nxsig_sleep() and nxsig_usleep().
Squashed commit of the following:

    Change all calls to usleep() in the OS proper to calls to nxsig_usleep()

    sched/signal:  Add a new OS internal function nxsig_usleep() that is functionally equivalent to usleep() but does not cause a cancellaption point and does not modify the errno variable.

    sched/signal:  Add a new OS internal function nxsig_sleep() that is functionally equivalent to sleep() but does not cause a cancellaption point.

9568600ab1 Squashed commit of the following:
This commit backs out most of commit b4747286b1.  That change was added because sem_wait() would sometimes cause cancellation points inappropriated.  But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.

    In the OS, all calls to sem_wait() changed to nxsem_wait().  nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.

    In all OS functions (not libraries), change sem_wait() to nxsem_wait().  This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.

    sched/semaphore:  Add the function nxsem_wait().  This is a new internal OS interface.  It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.

0f7210b0ae mtd: fix some unallocated and NULL pointer issues. rwb->wrflush and rwb->wrmaxblocks in rwbuffer could get unallocated values from ftl_initialize() in some configurations. Also fixes related assert:

that can happen with the following configuration:

  CONFIG_FTL_WRITEBUFFER=y
  CONFIG_DRVR_WRITEBUFFER=y
  # CONFIG_FS_WRITABLE is not set

These problems are caused by CONFIG variable differences between the buffer layers. TODO: This is not a perfect solution. readahead support has similar issues.

Byte-oriented read/write interfaces of mtd device accept the
target address in a byte offset, not a block number.

BUT. re-reading the datasheet, the WREN instruction is required to enable the execution of this command. This was not done.

I have no idea how the driver currently works except by chance. The writes
should never happen at all, the flash is half-enabled!
