[PATCH RFC 0/2] ds3000 firmware loading improvements

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

 



Hi all,

Please consider these 2 patches as an RFC, especially the first one.

The first patch is something I've found while trying to wrap my head
around the driver and I could find no legitimate reason to keep this
lock since commit b9bf2ea, as dvb_frontend_init() is now only called in
a single thread within dvb_frontend_thread().

Here's a little context for the second patch: we (SmartJog) have found
a few TeVii S470/471 cards where the ds3000 front-end *sometimes*
reports that it already has a loaded firmware (the 0xb2 register) yet
the card does not really work. That's why I've added the printk() in
the second patch to display when such a case happens.

We thus have an extra patch that adds a module parameter to force the
firmware loading, regardless of the 0xb2 register's state. This patch
allows us to use cards that would otherwise fail. Would such a patch be
of interest?

Would a patch that completely removes the register check (and thus
always loads the firmware at init time) be a preferred alternative?

Thanks for any pointers/reviews.

Rémi Cardona
