a7265d71c6 This commit adds support for default signal actions for SIGSTOP, SIGSTP, and SIGCONT.
Squashed commit of the following:

    Add procfs support to show stopped tasks.  Add nxsig_action() to solve a chicken and egg problem:  We needed to use sigaction to set default actions, but sigaction() would refuse to set actions if the default actions could not be caught or ignored.

    sched/signal:  Add configuration option to selectively enabled/disable default signal actions for SIGSTOP/SIGSTP/SIGCONT and SIGKILL/SIGINT.  Fix some compilation issues.

    sched/sched:  Okay.. I figured out a way to handle state changes that may occur while they were stopped. If a task/thread was already blocked when SIGSTOP/SIGSTP was received, it will restart in the running state.  I will appear that to the task/thread that the blocked condition was interrupt by a signal and returns the EINTR error.

    sched/group and sched/sched:  Finish framework for continue/resume logic.

    sched/signal:  Roughing out basic structure to support task suspend/resume

8d68d9ca43 arch/arm/src/stm32, stm32f7, stm32l4, and related defconfig files: The STM32 RTC driver was being selected by the global CONFIG_RTC option. That is in correct. For example, if you want to disabled the STM32 RTC and use an external RTC you cannot because the external RTC also depends on the global CONFIG_RTC. The solution is to add a new CONFIG_STM32xx_RTC configuration option the permits to you select or deselect the STM32 RTC but still be able to selecte the external RTC. 2018-08-08 12:42:04 -06:00

4becaea8e3 This commit extends support for the two-pass build. Its primary purpose is to incorporate source logic generated by applications into the kernel phase of the build.
In the two pass build, the application logic is built during the first phase, pass 1.  In that phase, the application may generate and install source files in the pass1/directory.  The operating system is built during phase 2 of the build.  At that time, those source files in the pass1/ directory will be built and incorporated into the kernel address space.

The primary purpose of the pass1/ directory is to such application-generated kernel symbol tables.  For an example of the use of this feature, look at apps/examples/module/drivers/Makefile.  Kernel symbol tables are needed to support kernel modules.  Of course, addition board-specific logic in, say, configs/<board>/src would have to be included to make use of the application-installed symbol tables.

binfmt/, libs/libc/unistd, and others:  Rename CONFIG_EXECFUNCS_SYMTAB to CONFIG_EXECFUNCS_SYMTAB_ARRAY.  Rename CONFIG_EXECFUNCS_NSYMBOLS to CONFIG_EXECFUNCS_NSYMBOLS_VAR.  Unlike CONFIG_EXECFUNCS_NSYMBOLS, CONFIG_EXECFUNCS_NSYMBOLS_VAR holds the name of an 'int' variable that contains the number of symbols in the symbol table.

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.

a540806ecf configs/indium-f7: Removes support for the Indium-F7 board. This was done for two reasons: (1) The board support was just clone of the Nucleo-144 board support with naming changes. There has been no support and no further development for the board support. (2) There does not seem to be any available Indium-F7 board available to the public anywhere on the internet. There is not even a reference to the board on the rafresearch.com web stie. Gotta go. Its in the way. 2018-05-24 13:09:20 -06:00

9da3d4a2a9 drivers/lcd and configs/olimex-lpc1766stk: Remove support for the Nokia6100 LCD. That LCD uses a 9-bit SPI interface (the 9th bit being the command/data bit that is normally a discrete). That communication was never successfully integrated. I now believe that it would would require some special support from the low-level, MCU SPI driver to manage that 9th bit. The deleted code is still available in the Obsoleted repository in the nuttx/drivers/lcd, nuttx/configs/olimex-lpc1766stk, and Patches directories. 2018-05-19 16:46:21 -06:00
