gprof Support

2024-03-20 Thread Joel Sherrill

Hi

Did gprof support some along as a side-effect of gcov support?

Any hints on getting it working appreciated.

What is the issue you are wanting to solve removing the flush?

[PATCH] bsps: Move declarations to

2024-03-20 Thread Sebastian Huber

Move declarations of bsp_interrupt_get_affinity() and
bsp_interrupt_set_affinity() to .  Canonicalize the
 includes.

Implement bsp_interrupt_get_affinity() and bsp_interrupt_set_affinity() only if
needed (usually RTEMS_SMP).

Provide stub implementations for i386 to fix build errors.

[PATCH] Mark parameters as intentionally unused

2024-03-20 Thread Sebastian Huber

The parameters are unused due to API constraints.  The functions are
used through function pointers.  Alternative implementations may use the
parameters.

Close #4862.

Yes, but this BSP is quite new. I would prefer to let it not flush anything by
default to carry out a reset.


I'd be fine with this being enabled for the AArch64 BSPs as well, but I
imagine that's better as a separate patch.

Why should it be enabled by default? The arm/xilinx-zynq and arm/xilinx-zynqmp
BSPs were the only ones doing an UART flush in the general termination
procedure. It probably was done to address a specific use case (maybe test 
runs).

Is the issue the flush is before an infinite loop which means the UART FIFO
should drain?


I don't really like the new bsp_flush_kernel_char_output() function. Another
approach could be an API change of

/**
  * @ingroup RTEMSAPIKernelCharIO
  *
  * @brief Polled character output functions shall have this type.
  */
typedef void ( *BSP_output_char_function_type )( char );

to something like this

typedef int ( *BSP_output_char_function_type )( int action );

If action in {0, ..., 255}, then print out the character. If 0x100 is set, then
flush the output device. If 0x200 is set, then do Y... The return value could be
used to give a status indication.

This could then be use for example by test runs, to flush the test output after
the end of the test.

This also requires a code change so is a flush function that bad an option?


You can change the character output handler since this is only a global 
variable (BSP_output_char). So, this bsp_flush_kernel_char_output() may 
not flush the device used by BSP_output_char. Doing a flush through the 
output handler lets you do the flush for the currently used device.


If we change the function type to

typedef int ( *BSP_output_char_function_type )( int action );

then we can add more features later if needed. Another feature which 
could be useful is: Output char immediately if possible and return 0, 
otherwise do nothing and return -1. This can be used to implement a 
full-duplex transfer in polling mode for the kernel I/O stream.

[PATCH] bsps: Avoid unused argument in clock interrupt

2024-03-20 Thread Sebastian Huber

Pass the parameter of the clock interrupt handler to
Clock_driver_support_at_tick() and Clock_driver_timecounter_tick().  This makes
it possible to use the interrupt handler argument in clock drivers.

Use the interrupt handler provided by Clock_driver_support_install_isr() to
avoid local delarations of Clock_isr().

Update #4862.

Re: [PATCH] Do not define CONFIGURE_TICKS_PER_TIMESLICE to 0

This is the problem of the referenced ticket:

https://devel.rtems.org/ticket/4986



If zero is to be an error, then that needs to change.


This is what the patch does.



Further, this series of changes has made me realize that 
CONFIGURE_TICKS_PER_TIMESLICE and CONFIGURE_MICROSECONDS_PER_TICK should 
not be defined if the application has not defined 
CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER. Currently the documentation 
just says it has no effect.


This is a different topic. I would like to first fix the undefined 
behaviour if some uses:


#define CONFIGURE_TICKS_PER_TIMESLICE 0



Also the formatting of the text in the description is inconsistent. 
Could a ref be used for all of this?


The application shall define exactly one of the following configuration 
options


* :ref:`CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER`,
* ``CONFIGURE_APPLICATION_DOES_NOT_NEED_CLOCK_DRIVER``, or
* :ref:`CONFIGURE_APPLICATION_NEEDS_TIMER_DRIVER`,


Sorry, were is this in the patch?

RFC: Add API to get and set interrupt priorities for interrupt vectors

2024-03-20 Thread Sebastian Huber


Hello,

I added a ticket for a proposal for an API to get and set interrupt 
priorities for interrupt vectors:


https://devel.rtems.org/ticket/5002

I would like to implement this API at least for the BSPs using the 
ARM/AArch64 GIC.

[PATCH] Do not define CONFIGURE_TICKS_PER_TIMESLICE to 0

Unconditionally make a CONFIGURE_TICKS_PER_TIMESLICE value less than or equal
to zero an error.
