5a45130d5c usbdev/usbmsc: introduce USBMSC_WRMULTIPLE for faster writes
This patch introduces a configuration option USBMSC_WRMULTIPLE,
which is used to store multiple blocks into a larger chunk that
then gets written via the mmcsd_writemultiple() (in case mmcsd
is used).

The bottleneck with the current implementation is the poor
performance due to short block writes.  USBMSC_DRVR_WRITE()
always writes only one sector (with eMMC that's usually 512 bytes).
eMMC devices usually erase much larger regions with near constant
time (see Jedec JESD84-B51, Extended CSD register byte [225],
SUPER_PAGE_SIZE): 'This register defines one or multiple of
programmable boundary unit that is programmed at the same time.'

If USBMSC_WRMULTIPLE is defined, then USBMSC_NWRREQS is used to
allocate the write buffer size.  We don't want this to be the
default behavior yet as this may reveal unseen bugs in usb drivers
due to the faster overall performance.

Sample configurations with measured performance:

  - Without USBMSC_WRMULTIPLE: 470 Kb/s
  - With USBMSC_WRMULTIPLE, CONFIG_USBMSC_NWRREQS=4: 1.1 Mb/s
    (dd with bs=2k)
  - With USBMSC_WRMULTIPLE, CONFIG_USBMSC_NWRREQS=16: 5.2 Mb/s
    (dd with bs=8k)

No doubt, this feature alone may make the mass storage work 10
times faster than before with eMMC cards.

8d722709cd usbmsc: Add USBMSC_NOT_STALL_BULKEP for RP2040 workaround
The new configuration CONFIG_USBMSC_NOT_STALL_BULKEP avoids to go into
stall state when :
- Receiving SCSI_CMD_INQUIRY with flags or pagecode != 0
- Receiving SCSI_CMD_MODESENSE6 and return the result data shorter than
  the requested data size.
Instead of stall, it just ignores the error condition.

Originally the usb driver goes into the stall under the conditions
mentioned above to inform to the USB host that the requested SCSI feature
is not supported, or the result data is shorter than the requested data
size.
But, at this moment, RP2040 USB device driver cannot handle entering and
leaving stall state of the bulk endpoints well.  Once stalls, the host -
device communication stops and cannot be resumed.

I have investigated to solve the issue and found that the existing
RP2040 USB device driver implementation, TinyUSB
(https://github.com/hathach/tinyusb) mass-storage class driver doesn't
enter the stall state like the treatment of this patch.

So, I introduce this new configuration as the RP2040 workaround.
In the future, when the RP2040 USB device driver is fixed and can handle
the bulk endpoint stall correctly, this patch should be reverted.

dccd436a58 USBDEV RNDIS: Fix unaligned access caused by 4f66624
Previous fix to RNDIS response queueing caused unaligned access
to response buffer in some configurations. On ARM Cortex-M, this
would cause hardfault if optimizer used strd instruction.

Fix by allocating the buffer as uint32_t. RNDIS messages are always
a multiple of 4 bytes in size, so this ensures alignment.

94480305a7 USBDEV RNDIS: Improve error recovery
Gracefully handle output queue full conditions. This shouldn't happen
in practice as the host is supposed to limit the number of commands
simultaneously in execution.

4f66624ea3 USBDEV RNDIS: Fix occasional disconnections due to race condition
Sometimes Windows would send RNDIS_KEEPALIVE_MSG and RNDIS_QUERY_MSG close
to each other. This would cause the latter command to overwrite the reply for
the prior command. This in turn will cause Windows to drop the connection after
a 20 second timeout.

Easy way to reproduce the issue is to open the Windows "Adapter Status" dialog that
shows the realtime TX/RX byte counts. This causes multiple RNDIS_QUERY_MSGs per
second, and the connection will drop in less than an hour.

This commit fixes this issue, and other potential race conditions (such as USB
descriptor read in middle on RNDIS query) by using a separate queue for the reply
packets.

9ff1795760 Check return from nxsem_wait_initialize()
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution:  Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly.  This commit is only for rwbuffer.c and those files under drivers/serial, drivers/timers, and drivers/usbdev.

This commit completes that step for all of the files under drivers/.  Still remaining:  All of the files under arch/.

5c0e8e88b1 Revert "Makefile: move INCDIROPT to common place (#625)"
This reverts commit b9ace36fcc.

This change was added by PR 625 but has a serious logic flaw.  It removes all occurrences of INCDIROPT and replaces it with a definition in tools/Config.mk:

    else ifeq ($(WINTOOL),y)
      DEFINE = "$(TOPDIR)/tools/define.sh"
      INCDIR = "$(TOPDIR)/tools/incdir.sh" -w

This logic flaw is the Config.mk is included in all Make.defs files BEFORE WINTOOL is defined.  As a result, the definition is wrong in many places when building under Cygwin with a Windows native toolchain.

21aef0dd68 drivers/*/Kconfig: Consolidate driver Kconfig Files.
This commit does two things:

1. First, it reorganizes the driver Kconfig files so that each is self contained.  Before, a part of the driver configuration was in drivers/Kconfig and the rest was in in drivers/xyz/Konfig.  Now, all of the driver configuration is consolitated in the latter.

2. Second, this commit correct numerous serious errors introduced in a previous reorganization of the driver Kconfig files.  This was first noted by Nicholas Chin in PR270 for the case of the drivers/i2c/Kconfig but some examination indicates that the error was introduced into several other Kconfig files as well.

The nature of the introduced error was basically this:

- Nothing must intervene between the menuconfig selection and the following conditional configuration otpions.
- A previous PR erroneously introduced unconditional options between the menuconfig and the following confditional logic, thus corrupting the driver menus.

This error was easy to make because the driver Kconfig files were not well modularized.  Making them fully self-contained should eliminate this kind of error in the future.

237c0cca09 CDC ECM Ethernet over USB High Speed for SAMA5D36-Xplained #68
Author: Alan Carvalho de Assis <acassis@gmail.com>

    Run nxstyle against .c .h files and fix it

Author: Adam Feuer <adam@starcat.io>

Summary

    Adds CDC ECM Ethernet over USB High Speed for SAMA5D36-Xplained
      (and maybe other boards) (most of the code was there already,
      but didn't work out of the box for the SAMA5D36-Xplained)
    Only SAMA5D36-Xplained has been tested so far

Impact

    None if you don't use the CDC ECM Ethernet driver
    On SAMA5D36-Xplained, this adds high-speed Internet connectivity
      over USB 2.0 High Speed. via the USB CDC ECM Gadget driver.
    It may work on other boards too.
    This also fixed full-speed (low-speed) mode for the board too.

Limitations

    Hasn't been tested on anything other than SAMA5D36-Xplained board.

TODO

    Ideally this would include a composite RNDIS device so it would
      also work seamlessly on Windows. That is for a future PR
    Ideally this would include software to help configuration via
      mDNS/DNS-SD for plug and play compatibility with Linux and macOS.
      That is for a future PR.

Detail

    Only a few lines of C driver code needed to be changed, since the
      capability was there already. The rest is config and documentation.
    Changes the SAMA5D3-Xplained board bringup to match the SAMA5D3-EK
      board bringup
    A helper script to configure Linux routing and iptables NAT is also
      provided, along with documentation on how to use it.

Testing

    Manual, on a Ubuntu Linux 19.10 system and MacOS 10.14.6 Mojave
      MacBook Pro.

How To Verify

    Follow the new CDC ECM Ethernet over USB instructions in the board
      README.txt file

Commits:

    remove non-UTF-8 chars in comment and reformat

    removed unneeded comment markers

    instructions for using the defconfigs

    removed EMAC from config

    - to prove this example only needs the CDC ECM Ethernet over USB to work

    added CDC-ECM Ethernet over USB info to README

    added U-Boot image

    added netusb helper script

    - this can configure the Linux network interface and routes
      so you can ping or access the NuttX system via TCP/IP.

    renamed defconfig dirs to be ethernet-over-usb

    - was usb-over-ethernet which is not right

    added USB DMA to defconfigs

    updated readme with autoboot and debugging info

    bringing ethernet-over-usb examples into parity

    added cdc ecm ethernet over usb with telnetd config

    added defconfig

    only use phy interrupt if netdevices is ethernet

    - because now netdevice could be CDC ECM ethernet over usb
      which has no PHY interrupt

    add bringup to Makefile

    add bringup

    app init cleanup

    init cdc ecm driver and rndis driver; some cleanup

    fixed some typos and odd characters

87cf5c58ae Correct some problems with network timed events when there are multiple network devices in the configuration.
Squashed commit of the following:

Author: Gregory Nutt <gnutt@nuttx.org>

    Ran nxstyle against many of the affected files.  But this job was too big for today.  Many of the network drivers under arch are highly non-compiant and generate many, many faults from nxstyle.  Those will have to be visited again another day.

Author: Xiang Xiao <xiaoxiang@xiaomi.com>

    This effects all network drivers as well as timing related portions of net/: devif_poll_tcp_timer shouldn't be skipped in the multiple card case.  devif_timer will be called multiple time in one period if the multiple card exist, the elapsed time calculated for the first callback is right, but the flowing callback in the same period is wrong(very short) because the global variable g_polltimer is used in the calculation.  So let's pass the delay time to devif_timer and remove g_polltimer.

I changed the condition so that the composite driver checks not only if this is a "standard" message but if it is also directed to the device. Otherwise, the handling is delegated to the children of the composite device. 2019-03-26 21:54:01 -06:00

    This avoids "error: conflicting types for 'composite_initialize'"
    on some versions of GCC. Because of the cross-inclusion between
    usbdev.h and composite.h, the full declaration is not always
    available.

    The last string ID used by composite driver is 4, and
    the number of IDs used is 5 (0..4). The comparison
    strid <= COMPOSITE_NSTRIDS caused composite driver to

22cd0d47fa This commit attempts remove some long standard confusion in naming and some actual problems that result from the naming confusion. The basic problem is the standard MTU does not include the size of the Ethernet header. For clarity, I changed the naming of most things called MTU to PKTSIZE. For example, CONFIG_NET_ETH_MTU is now CONFIG_NET_ETH_PKTSIZE.
This makes the user interface a little hostile.  People thing of an MTU of 1500 bytes, but the corresponding packet is really 1514 bytes (including the 14 byte Ethernet header).  A more friendly solution would configure the MTU (as before), but then derive the packet buffer size by adding the MAC header length.  Instead, we define the packet buffer size then derive the MTU.

The MTU is not common currency in networking.  On the wire, the only real issue is the MSS which is derived from MTU by subtracting the IP header and TCP header sizes (for the case of TCP).  Now it is derived for the PKTSIZE by subtracting the IP header, the TCP header, and the MAC header sizes.  So we should be all good and without the recurring 14 byte error in MTU's and MSS's.

Squashed commit of the following:

    Trivial update to fix some spacing issues.
    net/: Rename several macros containing _MTU to _PKTSIZE.
    net/: Rename CONFIG_NET_SLIP_MTU to CONFIG_NET_SLIP_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_6LOWPAN_MTU to CONFIG_NET_6LOWPAN_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_ETH_MTU to CONFIG_NET_ETH_PKTSIZE.  This is not the MTU which does not include the size of the link layer header.  This is the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename the file d_mtu in the network driver structure to d_pktsize.  That value saved there is not the MTU.  The packetsize is the memory large enough to hold the maximum packet PLUS the size of the link layer header.  The MTU does not include the link layer header.

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.

42a0796615 Squashed commit of the following:
sched/semaphore:  Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable.  Changed all references to sem_post in the OS to nxsem_post().

    sched/semaphore:  Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable.  Changed all references to sem_destroy() in the OS to nxsem_destroy().

    libc/semaphore and sched/semaphore:  Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable.  Changed all references to sem_setprotocol in the OS to nxsem_setprotocol().  sem_getprotocol() was not used in the OS

83cdb0c552 Squashed commit of the following:
libc/semaphore:  Add nxsem_getvalue() which is identical to sem_getvalue() except that it never modifies the errno variable.  Changed all references to sem_getvalue in the OS to nxsem_getvalue().

    sched/semaphore:  Rename all internal private functions from sem_xyz to nxsem_xyz.  The sem_ prefix is (will be) reserved only for the application semaphore interfaces.

    libc/semaphore:  Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable.  Changed all references to sem_init in the OS to nxsem_init().

    sched/semaphore:  Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.

    sched/semaphoate:  Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.
