* | | [PATCH] atmel_serial: Fix roundoff error in atmel_console_get_optionsHaavard Skinnemoen2006-10-041-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The atmel_console_get_options() function initializes the baud, parity and bits settings from the actual hardware setup, in case it has been initialized by a e.g. boot loader. The baud rate, however, is not necessarily exactly equal to one of the standard baud rates (115200, etc.) This means that the baud rate calculated by this function may be slightly higher or slightly lower than one of the standard baud rates. If the baud rate is slightly lower than the target, this causes problems when uart_set_option() tries to match the detected baud rate against the standard baud rate, as it will always select a baud rate that is lower or equal to the target rate. For example if the detected baud rate is slightly lower than 115200, usart_set_options() will select 57600. This patch fixes the problem by subtracting 1 from the value in BRGR when calculating the baud rate. The detected baud rate will thus always be higher than the nearest standard baud rate, and uart_set_options() will end up doing the right thing. Tested on ATSTK1000 and AT91RM9200-EK boards. Both are broken without this patch. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Acked-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | | [PATCH] AVR32: Allow renumbering of serial devicesHaavard Skinnemoen2006-10-046-18/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow the board to remap actual USART peripheral devices to serial devices by calling at32_map_usart(hw_id, serial_line). This ensures that even though ATSTK1002 uses USART1 as the first serial port, it will still have a ttyS0 device. This also adds a board-specific early setup hook and moves the at32_setup_serial_console() call there from the platform code.

This got around the limitation that ioremap() isn't always available when the console is being initalized. This patch removes that hack and replaces it with a new "regs" field in struct atmel_uart_data that the board-specific code can initialize to a fixed virtual mapping for platform devices where this is possible. It also initializes the DBGU's regs field with the address the driver used to check against. On AVR32, the "regs" field is initialized from the physical base address when this it can be accessed through a permanently 1:1 mapped segment, i.e. the P4 segment. If regs is NULL, the console initialization is delayed until the "real" driver is up and running and ioremap() can be used.

| * | | [GFS2] inode_diet: Replace inode.u.generic_ip with inode.i_private (gfs)Theodore Ts'o2006-09-284-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.
