6653c5cbf3 Signals: Correct implementation of sigset(). It is not just signal() with a different name; it has some additional signal mask handling functionality 2016-04-11 09:04:54 -06:00

28a4ca6713 libc/signal and include/signal.h: Rename sigset() to signal(). sigset() is the System V function; signal() is the obsoleted POSIX name. These seem to be equivalent. Neither are relevant in modern POSIX programming but the name signal() probably has better credentials. sigset() is now relegated to a #define in signal.h that makes it equivalent to signal(). 2016-04-10 14:35:45 -06:00

2. Move list of signal actions from the task TCB to the task group.  Signal handlers are a property of the entire task group and not of individual threads in the group.  I know, I preferred it the other way too but this is more compliant with POSIX.

06438b0dcc Fix 64-bit clock-related constant value evaluation for AVR compiler 
This may be specific for Atmel AVR8 toolchain compiler.
The problem is that despite of being 8-bit architecture
avr-gcc supports uint64_t, but the following code

uint64_t value = 10000 * 1000;

produces a wrong negative value in the final code (tested
both with and without optimization).

The work-around is simple:

uint64_t value = 10000 * 1000L;

The code is a reduced part from sched/signal/sig_timedwait.c where
waitticks64 is calculated using NSEC_PER_TICK. This one is defined
as USEC_PER_TICK * NSEC_PER_USEC which leads to the example above.

06d83c6261 Introduce support for Atmel toolchain in-flash strings 
Atmel toolchain AVR compiler provides a transparent in-flash object support using __flash and __memx symbols. The former indicates to compiler that this is a flash-based object.  The later used with pointer indicates that the referenced object may reside either in flash or in RAM. The compiler automatically makes 32-bit pointer with flag indicating whether referenced object is in flash or RAM and generates code to access either in run-time. Thus, any function that accepts __memx object can transparently work with RAM and flash objects.

For platforms with a Harvard architecture and a very small RAM like AVR this allows to move all constant strings used in trace messages to flash in the instruction address space, releasing resources for other things.

This change introduces IOBJ and IPTR type qualifiers.  The 'I' indicates that the object may like in instruction space on a Harvard architecture machine.

For platforms that do not have __flash and __memx or similar symbols IOBJ and IPTR are empty, making the types equivalent to, for example, 'const char' and 'const char*'.  For Atmel compiler these will become 'const __flash char' and 'const __memx char*'.  All printf() functions and syslog() functions are changed so that the qualifier is used with the format parameter.

This change standardizes the driver statistics and puts the definition in the common network device structure defined in netdev.h where they can be accessed by network applications. All Ethernet drivers that collect statistics have been adapted to use these common statistics. 2015-11-26 12:08:09 -06:00
