| * V4L/DVB: uvc: Fix multiple symbols definitions with UVC gadget and host driversLaurent Pinchart2010-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The UVC gadget driver borrowed code from the UVC host driver without changing the symbol names. This results in a namespace clash with multiple definitions of several symbols when compiling both drivers in the kernel. Make all generic UVC functions and variables static in the UVC gadget driver, as the symbols are not referenced outside of the gadget driver. Rename the uvc_trace_param global variable to uvc_gadget_trace_param. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Curiously, there still is a configuration bit to control this, which means it can be set incorrectly. And even more curiously, many boards out there are improperly configured, even though the IT8720F datasheet claims that the internal routing of VCCH to VIN7 is the default setting. So we force the internal routing in this case. It turns out that all boards with the wrong setting are from Gigabyte, so I suspect a BIOS bug. But it's easy enough to workaround in the driver, so let's do it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Jean-Marc Spaggiari <jean-marc@spaggiari.org> Cc: stable@kernel.org

For RDMA CQs, however, returning CIDX_INC credits is only needed and desired when and if the CQ is armed for notification. This can lead to a GTS write returning credits that causes the HW to reject the credit update because it causes CIDX to pass PIDX. Once this happens, the CIDX/PIDX counters get out of whack and an application can miss a notification and get stuck blocked awaiting a notification. To avoid this, we allocate the HW IQ 2x times the requested size. This seems to avoid the false overflow failures. If we see more issues with this, then we'll have to add code in the poll path to return credits periodically like when the amount reaches 1/2 the queue depth). I would like to avoid this as it adds a PCI write transaction for applications that never arm the CQ (like most MPIs).
