868fa211bc Remove non-functional vestiges of OTGHS in FS mode (including OTGFS2); try to convert the stm32f429i-disco configuration to use OTGHS instead of OTFHS in FS mode (OTGFS2). But I don't have the boards and can't test 2014-10-07 15:25:31 -06:00

e4deeada85 More vfork(): If we get to vfork() via system call, then we need to clone some system call information so that the return form the cloned system call works correctly 2014-09-29 10:59:15 -06:00

1dc9768c1a Fix vfork(). Now that arguments are kept on the stack, the way that arguments are passed from parent to child in vfork() must change. This bug has always been present, but was not visible with the old strdup() way of passing arguments 2014-09-29 10:45:44 -06:00

f8170550e1 ARMv7-A: Modify up_fullcontextrestore() for CONFIG_BUILD_KERNEL. It changed CPSR while in kernel. That will crash is the new CPSR is user mode while executing in kernel space. Fixed by adding a SYS_context_restore system call. There is an alternative, simpler modification to up_fullcontextrestore() that could have been done: It might have been possible to use the SPSR instead of the CPRSR and then do an exception return from up_fullcontextrestore(). That would be more efficient, but I never tried it. 2014-09-12 08:04:27 -06:00
