This was done by the following script run from libbsp:
find * -name bsp.h | xargs -e grep -l "#ifndef.*_BSP_H" | while read b
do
echo $b
cpu=`echo $b | cut -d'/' -f1 | tr '[:lower:]' '[:upper:]' `
bsp=`echo $b | cut -d'/' -f2 | tr '[:lower:]' '[:upper:]' `
g="LIBBSP_${cpu}_${bsp}_BSP_H"
# echo $g
sed -e "s/ifndef _BSP_H/ifndef ${g}/" \
-e "s/define _BSP_H/define ${g}/" \
-i $b
done

basic VGA driver can be enabled during configure phase by exporting variable
USE_VGA=1 so that it is available in configure environment
cirrus driver is enabled the same way by exporting variable
USE_CIRRUS_GD5446=1

driver is not initialized by default
initialization is possible through multiboot command line option or
through the string variable (see fb_default_mode.h) set in user's module
allowing the driver to evaluate this variable after the two
modules are linked together

The current support for the Edison supports a single polled
UART for input and output plus a simulated clock tick. The
activities forward for supporting the Edison have been posted
on the RTEMS mailing lists and at:

This allows the support for the legacy COM1-COM4 serial ports
to be completely disabled. It is needed to prevent hangs on some
hardware. In particular, the Intel Edison where it is not present.

This allows the VGA and keyboard console to be completely disabled.
It is useful on PCs without displays and prevents a very slow boot
time on the Intel Edison.

The current algorithm scans all PCI busses (0..ff)
and all devices (0..31) on each bus for bridges
and determines the maximum of all subordinate
busses encountered.
However, the algorithm does not scan all functions
present in multi-function devices -- I have a PCI express
root complex (82801H) where multiple (non-zero index)
functions are 'PCI bridges' whose subordinate bus number is
missed by the original algorithm.
This commit makes sure that the scan
is extended to all functions of multi-function
devices.
See #2067

The dummy.c was a de-facto default configuration. Rename it to
default-configuration.c. Use unlimited objects and the stack checker.
This makes it easier for new RTEMS users which will likely use this file
if they just work with the usual main() function as the application
entry point. Provide proper arguments for main() using the BSP command
line. Add spare user extensions and drivers.
Do not initialize the network by default. Delete bspinit.c.

structs, break >80 chars lines, removed newlines at EOFs
fb_vesa_rm.c: removed inline from functions declared in fb_vesa.h
removed unnecessary printks in the end of patch
edid.h, vbe3.h: switched from custom *PACKED_ATTRIBUTE at the structs to the
RTEMS_COMPILER_PACKED_ATTRIBUTE for easier maintainability

If USE_VBE_RM is 0, vesa_realmode_bootup_init() is not available so the
test should be #if instead of #ifdef.

crt.h defines such lovely constants as "RED" and "GREEN" which
have a nasty habit of conflicting with non-BSP code. There is
no reason to include this private .h from bsp.h and pollute the
namespace for applications.

This change starts with removing the effectively empty file
timerdrv.h. The prototypes for benchmark_timer_XXX() were in
btimer.h which was not universally used. Thus every use of
timerdrv.h had to be changed to btimer.h. Then the prototypes
for benchmark_timer_read() had to be adjusted to return
benchmark_timer_t rather than int or uint32_t.
I took this opportunity to also correct the file headers to
separate the copyright from the file description comments which
is needed to ensure the copyright isn't propagated into Doxygen
output.

With this patch the preinstall.am files are in a set order and not
dependent on now perl implements a hash.

section and a nonempty TLS BSS section.

Clustered/partitioned scheduling helps to control the worst-case
latencies in the system. The goal is to reduce the amount of shared
state in the system and thus prevention of lock contention. Modern
multi-processor systems tend to have several layers of data and
instruction caches. With clustered/partitioned scheduling it is
possible to honour the cache topology of a system and thus avoid
expensive cache synchronization traffic.
We have clustered scheduling in case the set of processors of a system
is partitioned into non-empty pairwise-disjoint subsets. These subsets
are called clusters. Clusters with a cardinality of one are partitions.
Each cluster is owned by exactly one scheduler instance.

Add and use _CPU_SMP_Start_processor(). Add and use
_CPU_SMP_Finalize_initialization(). This makes most
_CPU_SMP_Initialize() functions a bit simpler since we can calculate the
minimum value of the count of processors requested by the application
configuration and the count of physically or virtually available
processors in the high-level code.
The CPU port has now the ability to signal a processor start failure.
With the support for clustered/partitioned scheduling the presence of
particular processors can be configured to be optional or mandatory.
There will be a fatal error only in case mandatory processors are not
present.
The CPU port may use a timeout to monitor the start of a processor.

Rename rtems_smp_process_interrupt() into
_SMP_Inter_processor_interrupt_handler(). Delete unused header file
<rtems/bspsmp.h>.

Rename rtems_smp_secondary_cpu_initialize() into
_SMP_Start_multitasking_on_secondary_processor(). Move declaration to
<rtems/score/smpimpl.h>.

Since the per-CPU SMP lock must be acquired and released to send the
message a single interrupt broadcast operations offers no benefits. If
synchronization is required, then a SMP barrier must be used anyway.
|

|
|
|

Rename bsp_smp_initialize() into _CPU_SMP_Initialize() since every CPU
port must supply this function.

pc386 set CLOCK_DRIVER_ISRS_PER_TICK to a

CLOCK_DRIVER_ISRS_PER_TICK_VALUE and
other clean up on the clock driver.
