#2796 closed defect (fixed)

GRETH: Interrupt Handler broken (patch attached)

Reported by: Christian Spindeldreier Owned by: Daniel Hellstrom
Priority: high Milestone: 4.11
Component: network/legacy Version: 4.11
Severity: major Keywords: GRETH leon sparc interrupt event broken
Cc: Blocked By:


The interrupt handler in the driver manager based Leon ethernet driver (GRETH) is broken (/src/lib/libbsp/sparc/shared/net/greth.c)

The interrupt handler uses rtems_event_send() to send a Event to the daemon Task which fails with RTEMS_INVALID_ID in rtems-4.11.

To fix this the inline function rtems_bsdnet_event_send() defined in rtems_bsdnet_internal.h should be used. A corresponding patch is attached.

You're right this looks wrong, the rest of the driver uses rtems_bsdnet_event_*() interface. I haven't tried your patch or the GRETH driver on the master for a while now, but the patch looks OK to be committed.

The patch works correctly.
rtems_bsdnet_event_* uses rtems_event_system_* so they don't work with the rtems_event_send currently in the driver.
The second greth driver "c/src/libchip/network/greth.c" is already correct.
Can someone commit?

I will commit this but need a name to put on the commit.

Also this needs to go on the 4.11 branch.

I will handle it once I get the proper attribution. Thanks.

Attribution wasn't the primary thing holding it up. Daniel needed to review it.

But when I went to commit it, I realized that I didn't know the right name to put on it. :)

FYI submitting patches from git using git format-patch, etc. is better since it keeps the maintainers from writing the change message. :)

Thanks for the patch. It should now be correctly on the 4.11 branch and master. If not, reopen the ticket and ping it.
