This patch adds the "--printk=" boot command line argument to specify
the printk() device. It also enhances the "--console=" boot command
line argument to match any device configured in the console device
table. The arguments are parsed as early as possible so they take
effect early. Currently, this is immediately after PCI initialization.

configuration space
This patch fundamentally results from enhancements to the pc386 BSP
to support systems which do **NOT** have the legacy PCI BIOS. The
patch adds support for detecting when legacy PCI BIOS is not
present and then using IO space to access to PCI Configuration Space.
This resulted in dynamically selected between two implementations
of PCI and refactoring out the shared methods.
This patch adds shared implementations of pci_bus_count() and
pci_find_device(). Subsequent patches will remove implementations
of these methods in other BSPs where possible.

This first step eliminates the following as public APIs for the pc386
BSP:
+ pcib_conf_read8
+ pcib_conf_read16
+ pcib_conf_read32
+ pcib_conf_write8
+ pcib_conf_write16
+ pcib_conf_write32
The if_fxp.c driver uses these enough where I provided local macros
to allow the code to be mostly unmodified. On other architectures
these names have been used privately. It will take multiple patches
to completely eliminate these symbols from the RTEMS source tree.
The focus of the first effort is just to eliminate these as a public
pc386 API so support can be added for systems without legacy PCI BIOS.

This avoids potential dead code in _Thread_Handler(). It gets rid of
the dangerous function pointer casts.

Notepads where a feature of RTEMS' tasks that simply functioned in
the same way as POSIX keys or threaded local storage (TLS). They were
introduced well before per task variables, which are also deprecated,
and were barely used in favor of their POSIX alternatives.
In addition to their scarce usage, Notepads took up unnecessary memory.
For each task:
- 16 32-bit integers were allocated.
- A total of 64 bytes per task per thread.
This is especially critical in low memory and safety-critical applications.
They are also defined as uint32_t, and therefore are not guaranteed to
hold a pointer.
Lastly, they are not portable solutions for SMP and uniprocessor systems,
like POSIX keys and TLS.
updates #2493.

Use the bsp_predriver_hook() instead.
Update #2408.
|
|
Call bsp_work_area_initialize() before bsp_start(). This allows
bsp_start() to use malloc() etc. which is beneficial for systems with a
plug-and-play hardware enumeration.
Update #2408.

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

closes #2364.

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:
http://rtemsramblings.blogspot.com/2014/12/intel-edison-and-rtems-road-forward.html

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

Some includes may use C++ and this conflicts if surrounded extern "C".

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.

The TLS section symbols had wrong values in case of an empty TLS data
section and a nonempty TLS BSS section.
