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

Gregory Nutt
64ab35b399 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

c9661ad5a7 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
0aa7209765 Change CONFIG_MSEC_PER_TICK to CONFIG_USEC_PER_TICK. This gives more options for system timers in general, but more importantly, let's us realize higher resolution for the case of CONFIG_SCHED_TICKLESS=y -- of course, at the risk of some new interger overvflow problems 2014-08-07 13:42:47 -06:00

Gregory Nutt
276cc44878 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
Gregory Nutt
4df0fbec04 SAMA5D HSMCI: Fix a problem on card insertion/removal callback handling. Interrupts were being disable so that the callbacks occurred with interrupts disabled. This resulted in loss of some interrupts and some not-so-good behaviors. The solution is to perform all callbacks on the work thread unconditionally (2014-7-29). 2014-07-30 10:19:41 -06:00

7f5b88dbcd 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.
