9aae0adffa If we are configured to use a kernel stack while in SYSCALL handling, then we need to switch back to the user stack to deliver a signal 2014-09-15 11:38:48 -06:00

fba35f0c41 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

Gregory Nutt
31b8137956 There used to be two ways to pass parameters to new tasks, depending upon the configuration: Either (1) argv[] as created as an array with each string strdup'ed. Or (1) argv[] array and strings were created on the stack before the new task was started. Now, there is only one way, way (1). Way (2) might be slightly more compact, but this is not worth carry the complexity of two different ways of doing the same thing. 2014-09-01 15:39:34 -06:00

39183d37b8 Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions. Something likely got broken doing this, probably because I confused a MSEC2TICK conversion with a TICK2MSEC conversion. Also, the tickless OS no appears fully functional and passes the OS test on the simulator with no errors 2014-08-07 18:00:38 -06:00
Gregory Nutt
594083d870 Rename up_timerinit() to up_timer_initailize(); Add prototypes for candidate interfaces for the tickless OS; Don't build existing timer initialization logic if CONFIG_SCHED_TICKLESS is defined. 2014-08-06 16:26:01 -06:00

c0c4cda763 SAMA5 HSMCI: e-enable TX DMA and verify that DMA writes to the SD card are functional. They are so now TX DMA is re-enabled in the driver. This might affect the SAMA5D3 platforms where the TX DMA problem was found. The SAMA4D3 and 4 use the same HSMCI driver. Much has change since then and it is not surprising that DMA is now functional. However, the has not be re-verified on the SAMA5D3 which has a different DMA controller. 2014-07-30 11:20:06 -06:00

611ea42dbf SAMA5D HSMCI: Fix a problem on card insertion/removal callback handling. Interrupts were being disable so that the callbacks occurred with interrupts disabled.

a3d20b2fa1 LPC17 Ethernet: Added option to use the kernel worker thread to do most of the workload with CONFIG_NET_WORKER_THREAD option in Kconfig. Eliminated a problem with PHY DP83848C : it doesn't need a specific initialization on mbed. Critical bufix: From time to time (after some hours) the Ethernet receiver would lose one receive interrupt and the IP stack never recover because there is no receive watchdog as the transmit watchdog.
