Re: python dependencies Ubuntu 15.04
Hello, just a wild guess: Which python Version is default on Ubuntu? Most distributions use python2 as default. I know that e.g. Arch uses python3. Just try a python --version to find out. Kind regards Christian Mauderer Am 12.08.2015 um 10:38 schrieb punit vara: sudo apt-get install python-all-dev I have done this .Still python error.

Protected and Unprotected operations on Chain_control
Hi, For operations related to manipulation of Chain_Node we have two modes for that: protected and unprotected. In protected access to chain we guard the operation by disabling the interrupts while in unprotected we don't guard it. Is it that we don't disable interrupts in unprotected mode because we are sure that ISR will not affect the operation and with protected ISR may affect the operation so we guard operation against it. When is protected and unprotected used in respect with the context? Thanks, Saurabh Gadia ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
Re: Protected and Unprotected operations on Chain_control
thread dispatch occurs due to an interrupt. if interrupts are
disabled, then no dispatch.

Hi,
#define _ISR_Disable( _level ) \
do { \
_CPU_ISR_Disable( _level ); \
_Assert( _Debug_Is_owner_of_giant() ); \
RTEMS_COMPILER_MEMORY_BARRIER(); \
} while (0)
the above macro has description:
@brief Disables interrupts on this processor.
*
* This macro disables all interrupts on this processor so that a critical
* section of code is protected from concurrent access by interrupts of
this
* processor. Disabling of interrupts disables thread dispatching on the
* processor as well.
*
* On SMP configurations other processors can enter such sections if not
* protected by other means.
*
* @param[out] _level The argument @a _level will contain the previous
* interrupt mask level.
*/
And :
#define _ISR_Disable_without_giant( _level ) \
do { \
_CPU_ISR_Disable( _level ); \
RTEMS_COMPILER_MEMORY_BARRIER(); \
} while (0)
The above lock is acquired for SMP.
But how are both macros different. With former Macro it disables all
interrupts as level is highest but how does it ensure
thread_dispatch_disable?
Thanks,
Saurabh Gadia

Correct. unprotected means something else has already ensured mutual
exclusion.

Re: Fwd: SMP support for Raspberry Pi 2
Hi, It would be great if somebody can help here. [1] How are the mailbox registers available for each core of Pi2 to be used. [2] Another thing is that I don't know which registers of Pi 1 are available for Pi2 as well. The ones in this link https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2836/QA7_rev3.4.pdf , are quite different from the ones for Pi 1. [3] Can the same mailbox interface as Pi1 be used? Thanks.

Also the clock driver, etc. The actual handler and IRQ number will vary.

During final initialization of SMP I can see rtems_interrupt_handler_install( ARM_GIC_IRQ_SGI_0, IPI, RTEMS_INTERRUPT_UNIQUE, bsp_inter_processor_interrupt, NULL ); Raspberry Pi 2 does not have the generic interrupt controller. Interrupt routing will have to be handled differently. So I wish to understand how/ where it is used. I suppose this might be the problem. Sorry, that the documentation is so scattered. I think we should move everything into the CPU Architecture Supplement. It would be nice if you can help to improve the documentation since you have a different view point. What is the CPU Architecture Supplement? You must install the IPI during the system initialization. It is raised via the _CPU_SMP_Send_interrupt() function, for an example see arm-a9mpcore-smp.c.

Re: Protected and Unprotected operations on Chain_control
On Wed, Aug 12, 2015 at 11:48 AM, Saurabh Gadia ga...@usc.edu wrote: Hi, For operations related to manipulation of Chain_Node we have two modes for that: protected and unprotected. In protected access to chain we guard the operation by disabling the interrupts while in unprotected we don't guard it. Is it that we don't disable interrupts in unprotected mode because we are sure that ISR will not affect the operation and with protected ISR may affect the operation so we guard operation against it. When is protected and unprotected used in respect with the context? Correct. unprotected means something else has already ensured mutual exclusion.

Hi,
So here I patch the configure.in file instead of its output. If this one is
good to go, I'll send you the two other patches for microwindows-bset and
t1lib-bset , with its' correct patch urls.
The patch has to include the source (configure.in) and generated
file (configure). Once the patch is applied, the configure script
should match what would be generated but the end user is not expected
to be able to generate the configure script.
Include both files and ensure the configure is actually generated
from the latest configure.in.
I've added the generation in the build process. After the configure.in is
patched, I regenerate the configure script. Is that ok?
Best wishes

Re: [PATCH 1/1] add t1lib patch
Hi,
So here I patch the configure.in file instead of its output. If this one is
good to go, I'll send you the two other patches for microwindows-bset and
t1lib-bset , with its' correct patch urls.
Best wishes

Re: Protected and Unprotected operations on Chain_control
Hi,
#define _ISR_Disable( _level ) \
do { \
_CPU_ISR_Disable( _level ); \
_Assert( _Debug_Is_owner_of_giant() ); \
RTEMS_COMPILER_MEMORY_BARRIER(); \
} while (0)
the above macro has description:
@brief Disables interrupts on this processor.
*
* This macro disables all interrupts on this processor so that a critical
* section of code is protected from concurrent access by interrupts of
this
* processor. Disabling of interrupts disables thread dispatching on the
* processor as well.
*
* On SMP configurations other processors can enter such sections if not
* protected by other means.
*
* @param[out] _level The argument @a _level will contain the previous
* interrupt mask level.
*/
And :
#define _ISR_Disable_without_giant( _level ) \
do { \
_CPU_ISR_Disable( _level ); \
RTEMS_COMPILER_MEMORY_BARRIER(); \
} while (0)
The above lock is acquired for SMP.
But how are both macros different. With former Macro it disables all
interrupts as level is highest but how does it ensure
thread_dispatch_disable?
Thanks,

Hi,
For operations related to manipulation of Chain_Node we have two modes
for
that: protected and unprotected. In protected access to chain we guard
the
operation by disabling the interrupts while in unprotected we don't guard
it. Is it that we don't disable interrupts in unprotected mode because we
are sure that ISR will not affect the operation and with protected ISR
may
affect the operation so we guard operation against it. When is protected
and
unprotected used in respect with the context?
Correct. unprotected means something else has already ensured mutual
exclusion.
Thanks,
