[MTD] mtdoops: Fix a bug where block may not be erased

2008-10-18T10:51:48+00:00

This makes the driver erase a block when it doesn't find any existing saved log messages which is safer than assuming the flash was already erased. Signed-off-by: Richard Purdie Signed-off-by: David Woodhouse

[MTD] mtdoops: Add a magic number to logged kernel oops

2008-10-18T10:51:27+00:00

Add a magic number to logged kernel oops messages so that they can be more accurately detected rather than just having to rely on the sequence number. This also allows easier detection of saved crashes by userspace. Signed-off-by: Richard Purdie Signed-off-by: David Woodhouse

[MTD] mtdoops: Fix an off by one error

[MTD] mtdoops: Use the panic_write function when present

2008-02-07T10:31:04+00:00

When the MTD provides a panic_write function, use it. Signed-off-by: Richard Purdie Signed-off-by: David Woodhouse

[MTD] mtdoops: Various minor cleanups

2008-02-03T07:19:24+00:00

Various minor cleaups to mtdoops: * Don't support the mtd->erasesize < OOPS_PAGE_SIZE case * Tweak printks and make the device mtdoops connects to more visible * CON_PRINTBUFFER flag is uneeded Signed-off-by: Richard Purdie Signed-off-by: David Woodhouse

[MTD] mtdoops: Ensure sequential write to the buffer

2008-02-03T07:18:58+00:00

Add a spinlock to ensure writes to the mtdoops buffer memory are sequential and don't race. Signed-off-by: Richard Purdie Signed-off-by: David Woodhouse

[MTD] mtdoops: Perform write operations in a workqueue

2008-02-03T07:14:41+00:00

Writing to the flash needs to be done in a workqueue. The console write functions may be called in any context which can lead to lockups otherwise. Signed-off-by: Richard Purdie Signed-off-by: David Woodhouse

[MTD] mtdoops: Add further error return code checking

2008-02-03T07:14:35+00:00

Add further error return code checks to the mtdoops driver. Signed-off-by: Richard Purdie Signed-off-by: David Woodhouse
