[PATCH 00/13] staging: ti dspbridge: deh rewrite

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Investigating the MMU fault corruption issue I found a lot of areas of
improvements of the exception handling code.

Moreover, even though the obvious memory corruption is fixed on kernel side,
there are still some rare cases where corruption in user-space might be
possible if some buffers are still mapped. This came up in a discussion with
Fernando Lugo, and we both agreed on a fix (patch #7).

The rest is mostly reorganization.

(This is basically the same as the old one, but rebased to staging tree)
