Gregory Nutt bfb93338f6 Move net/iob to drivers/iob so that the I/O buffering feature can be available to other drivers when networking is disabled. 2017-04-20 16:08:49 -06:00
Gregory Nutt 370e188fa3 Convert more drivers to use new interrupt argument structure. 2017-02-28 09:05:01 -06:00
Mark Schulte b3222bbc8a irq_dispatch: Add argument pointer to irq_dispatch
Provide a user defined callback context for irq's, such that when
registering a callback users can provide a pointer that will get
passed back when the isr is called.

Gregory Nutt c5b00ccfc4 SMP Signals: Fix some SMP signal delivery logic. Was not handling some critical sections correctly and was missing logic to signal tasks running on other CPUs. 2017-01-14 08:28:37 -06:00
Gregory Nutt 3ed091376c In all implementations of _exit(), use enter_critical_section() vs. disabling local interrupts. 2017-01-13 11:08:24 -06:00
Gregory Nutt c9b15ebb6a Xtensa ESP32: Remove call to sched_lock()/unock() from inter-cpu interrupt logic. Results in recursive call to sched_mergepending(). 2016-12-25 09:26:20 -06:00
Gregory Nutt b87fc91466 Revert "Xtensa SMP: Avoid a nasty situation in SMP by assuring that up_release_pending() is not re-entered."
This reverts commit 733a57b4df.

Gregory Nutt efb86382c3 SMP: Back out deferred IRQ locking. This was accidentally merged into master and it looks like it is going to be more work than I thought to get it working again. Changes will go to the irqlock branch. 2016-12-24 19:53:37 -06:00

Gregory Nutt 714e6f80ca Xtensa ESP32: Corrects a problem with dispatching to signal handlers: Cannot vector directly to the signal handling function as in other ABIs under the Xtensa Window ABI. In that case, we need to go through a tiny hook when performs the correct window call (call4) otherwise registers will be scrambled in the signal handler 2016-12-22 11:19:38 -06:00
Gregory Nutt d9a64b9ca9 Xtensa ESP32: Some fixes from integration of ostest configuration. Almost works: There are some assertions in xtensa_sigdeliver() 2016-12-22 09:34:39 -06:00
