Update #3678.
|
|
It enabled promiscous mode or sets the multicast filter according
to the configuration and parameters to ioctl(SIOCSIFFLAGS),
ioctl(SIOCADDMULTI) and ioctl(SIOCDELMULTI).
On SIOCADDMULTI/SIOCDELMULTI requests the greth ioctl calls the
Ethernet helper functions ether_addmulti()/ether_delmulti() which
tells the greth driver when its required to update the MAC multicast
filtering.
The interface notifies support for multicast by setting IFF_MULTICAST.
The GRETH has two registers which contains a bit-mask of allowed MAC
addresses. The incomming MAC address is CRC:ed and the CRC is used as
an index into the bit-mask to determine to allow or drop the frame.

A speciality of the RTEMS build system was the make preinstall step. It
copied header files from arbitrary locations into the build tree. The
header files were included via the -Bsome/build/tree/path GCC command
line option.
This has at least seven problems:
* The make preinstall step itself needs time and disk space.
* Errors in header files show up in the build tree copy. This makes it
hard for editors to open the right file to fix the error.
* There is no clear relationship between source and build tree header
files. This makes an audit of the build process difficult.
* The visibility of all header files in the build tree makes it
difficult to enforce API barriers. For example it is discouraged to
use BSP-specifics in the cpukit.
* An introduction of a new build system is difficult.
* Include paths specified by the -B option are system headers. This
may suppress warnings.
* The parallel build had sporadic failures on some hosts.
This patch removes the make preinstall step. All installed header
files are moved to dedicated include directories in the source tree.
Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc,
etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g.
erc32, imx, qoriq, etc.
The new cpukit include directories are:
* cpukit/include
* cpukit/score/cpu/@RTEMS_CPU@/include
* cpukit/libnetworking
The new BSP include directories are:
* bsps/include
* bsps/@RTEMS_CPU@/include
* bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include
There are build tree include directories for generated files.
The include directory order favours the most general header file, e.g.
it is not possible to override general header files via the include path
order.
The "bootstrap -p" option was removed. The new "bootstrap -H" option
should be used to regenerate the "headers.am" files.
Update #3254.

The EDCL and Duplex-Detection are now disabled during soft-reset
of the GRETH core.
The speed settings are preserved on boot and greth_stop() also,
this is required to keep EDCL operational when DD is set.

1. read_mii() now returns 0xffff on failure. It is more robust when it
comes to reading the reset bit in the control register, that is the
first access.
2. write_mii() now has error printout like read_mii().
3. Additional (optional) PHY access debugging is now available by
enabling GRETH_DEBUG_MII. Even successful accesses are printed.
4. Let PHY do power-down (not only reset) to get in a good state,
this is just in case the PHY input pin settings are sampled only
on PHY power-up on some PHYs.
5. PHY GBit advertisement is disabled if Gbit is not supported by MAC.
Or forced if supported.
6. Auto-nego is started if supported by PHY, before it was started only
if default set by PHY.
7. Reset Sequence updated:
* one must wait until reset bit is self-cleared.
* the DD (Disable Duplex Detection) bit is set, only affects
EDCL capable devices. This lets RTEMS handle PHY initialization

Most drivers use the Driver Manager for device probing, they
work on AMBA-over-PCI systems if PCI is big-endian.
New APIs:
* GPIO Library, interfaced to GRGPIO
* GENIRQ, Generic interrupt service implementation helper
New GRLIB Drivers:
* ACTEL 1553 RT, user interface is similar to 1553 BRM driver
* GR1553 (1553 BC, RT and BM core)
* AHBSTAT (AHB error status core)
* GRADCDAC (Core interfacing to ADC/DAC hardware)
* GRGPIO (GPIO port accessed from GPIO Library)
* MCTRL (Memory controller settings configuration)
* GRETH (10/100/1000 Ethernet driver using Driver manager)
* GRPWM (Pulse Width Modulation core)
* SPICTRL (SPI master interface)
* GRSPW_ROUTER (SpaceWire Router AMBA configuration interface)
* GRCTM (SpaceCraft on-board Time Management core)
* SPWCUC (Time distribution over SpaceWire)
* GRTC (SpaceCraft up-link Tele core)
* GRTM (SpaceCraft down-link Tele Metry core)
GR712RC ASIC specific interfaces:
* GRASCS
* CANMUX (select between OCCAN and SATCAN)
* SATCAN
* SLINK

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.

The ISR code is updated to use argument instead of global greth
structure, now that the greth private is available in the ISR.
The shared-irq routines will unmask the IRQ, so the forced LEON3
BSP unmask/clear IRQ is removed.
