| * | powerpc/mpc5121: move PSC FIFO memory init to platform codeAnatolij Gustschin2010-05-251-69/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since PSC could also be used in other modes than UART mode we move PSC FIFO memory initialization from serial driver to common platform code. The initialized FIFO memory slices may not overlap, so the most easy way would be to configure them all at once at init time for all PSC devices. This is now done by this patch.

* | | m68knommu: fix broken use of BUAD_TABLE_SIZE in 68328serial driverGreg Ungerer2010-05-251-1/+1
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 8b505ca8e2600eb9e7dd2d6b2682a81717671374 ("serial: 68328serial.c: remove BAUD_TABLE_SIZE macro") misses one use of BAUD_TABLE_SIZE. So the resulting 68328serial.c does not compile: drivers/serial/68328serial.c: In function `m68328_console_setup': drivers/serial/68328serial.c:1439: error: `BAUD_TABLE_SIZE' undeclared (first use in this function) drivers/serial/68328serial.c:1439: error: (Each undeclared identifier is reported only once drivers/serial/68328serial.c:1439: error: for each function it appears in.)

This was mostly a direct port from the original kdb where I cleaned up the code against checkpatch.pl and added the glue to stitch it into kgdb. This patch also enables early kdb debug via kgdbwait and the keyboard. All the access to configure kdb using either a serial console or the keyboard is done via kgdboc. If you want to use only the keyboard and want to break in early you would add to your kernel command arguments: kgdboc=kbd kgdbwait If you wanted serial and or the keyboard access you could use: kgdboc=kbd,ttyS0 You can also configure kgdboc as a kernel module or at run time with the sysfs where you can activate and deactivate kgdb.

This is required in order to get the page scrolling mechanism working. Changing the kernel debugger I/O API to require all polling character routines to exit immediately if there is no data allows the kernel debugger to process multiple input channels. NO_POLL_CHAR will be the return code to the polling routine when ever there is no character available. CC: linux-serial@vger.kernel.org Signed-off-by: Jason Wessel <jason.wessel@windriver.com>

In certain situations the IP reports that the FIFO is empty, but a byte is still clocked out. If a flush is done at that point the currently clocked byte is canceled. This causes incompatibilities with the upper layers when a port is closed, it waits until the FIFO is empty and then closes the port. During close the FIFO is flushed -> the last byte is not sent properly. Now the FIFO is only flushed if it is reported to be non-empty. Which makes the currently clocked out byte to finish.
