* [IB] uverbs: Add a mask of device methods allowed for userspaceRoland Dreier2005-10-17
| | | | | | | Give each device a uverbs_cmd_mask, so that a low-level driver can control which methods may be called on behalf of userspace. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB] fail SA queries if device initialization failedRoland Dreier2005-10-17
| | | | | | | | | If the SA query module's initialization fails for a device, then that device won't have a struct ib_sa_device associated. We should fail SA queries in that case, rather than blindly dereferencing the NULL pointer we get back from ib_get_client_data(). Signed-off-by: Roland Dreier <rolandd@cisco.com>

* [IPoIB] Rename ipoib_create_qp() -> ipoib_init_qp() and fix error cleanupRoland Dreier2005-10-17
| | | | | | | | | | ipoib_create_qp() no longer creates IPoIB's QP, so it shouldn't destroy the QP on failure -- that unwinding happens elsewhere, so the current code can cause a double free. While we're at it, the function's name should match what it actually does, so rename it to ipoib_init_qp(). Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB] mthca: Better limit checking and reportingJack Morgenstein2005-10-17
| | | | | | | | | Check the sizes of CQs, QPs and SRQs when creating objects, and fail instead of creating too-big queues. Also return real limits instead of just plausible-sounding values from mthca_query_device(). Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB] Fix leak on MAD initialization failureRoland Dreier2005-10-17
| | | | | | | | There is a bug in ib_mad_init_device(): if ib_agent_port_open() fails for a given port, then the current code doesn't call ib_mad_port_close() for that port. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB] mthca: detect SRQ overflowRoland Dreier2005-10-17
| | | | | | | | | The hardware relies on us keeping one extra work request that never gets used in SRQs. Add checks to the SRQ work request posting functions so that they fail when someone is about to use up that extra work request, rather than when someone uses the very last work request. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB] mthca: SRQ limit reached eventsRoland Dreier2005-10-17
| | | | | | | | | Our hardware supports generating an event when the number of receives posted to a shared receive queue (SRQ) falls below a user-specified limit. Implement mthca_modify_srq() to arm the limit, and add code to handle dispatching SRQ events when they occur. Signed-off-by: Roland Dreier <rolandd@cisco.com>

* [IB] uverbs: reject invalid memory registration permission flagsRoland Dreier2005-10-17

* [IB] uverbs: Fix up resource creation error pathsRoland Dreier2005-10-17
| | | | | | | | | | | | By waiting to add resources to our lists until after the last operation that can fail, we don't have to remove them from their lists in the error path. Also, we should hold the idr mutex until we know whether resource creation has succeed or failed, to avoid someone finding a resource in our table before we're ready. Loosely based on work by Robert Walsh <rjwalsh@pathscale.com>. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB] uverbs: ABI-breaking fixes for userspace verbsRoland Dreier2005-10-17
| | | | | | | | | | Introduce new userspace verbs ABI version 3. This eliminates some unneeded commands, and adds support for user-created completion channels. This cleans up problems with file leaks on error paths, and also makes sure that file descriptors are always installed into the correct process. Signed-off-by: Roland Dreier <rolandd@cisco.com>

* [PATCH] fix black/white-only svideo input in vpx3220 decoderRonald S. Bultje2005-10-17
| | | | | | | | | | | | Fix the fact that the svideo input will only give input in black/white in some circumstances. Reason is that in the PCI controller driver (zr36067), after setting input, we reset norm, which overwrites the input register with the default. This patch makes it always set the correct value for the input when changing norm. Signed-off-by: Ronald S.

* [PATCH] fix vpx3220 offset issue in SECAMRonald S. Bultje2005-10-17
| | | | | | | | | | | | | | Fix bug #5404 in kernel bugzilla. It basically updates the vpx3220 initialization tables with some newer values that we've had in CVS for a while (and that, for some reason, never ended up in the kernel... must've gotten lost). Those fix a ~16 pixels noise at the top of the picture in at least SECAM, although (now that I think about it) PAL was probably affected, also. Signed-off-by: Ronald S.

* [PATCH] SVGATextMode fixSamuel Thibault2005-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix bug 5441. I didn't know about messy programs like svgatextmode... Couldn't this be integrated in some linux/drivers/video/console/svgacon.c ?... So because of the existence of the svgatextmode program, the kernel is not supposed to touch to CRT_OVERFLOW/SYNC_END/DISP/DISP_END/OFFSET ? Disabling the check in vgacon_resize() might help indeed, but I'm really not sure whether it will work for any chipset: in my patch, CRT registers are set at each console switch, since stty rows/cols apply to consoles separately... The attached solution is to keep the test, but if it fails, we assume that the caller knows what it does (i.e. it is svgatextmode) and then disable any further call to vgacon_doresize. Svgatextmode is usually used to _expand_ the display, not to shrink it. And it is harmless in the case of a too big stty rows/cols: the display will just be cropped. I tested it on my laptop, and it works fine with svgatextmode. A better solution would be that svgatextmode explicitely tells the kernel not to care about video timing, but for this an interface needs be defined and svgatextmode be patched.

* [PATCH] usbserial: Regression in USB generic serial driverRandall Nortman2005-10-14
| | | | | | | | | | | | Kernel version 2.6.13 introduced a regression in the generic USB serial converter driver (usbserial.o, drivers/usb/serial/generic.c). The bug manifests, as far as I can tell, whenever you attempt to write to the device -- the write will never complete (write() returns 0, or blocks).

* | [PATCH] wireless/airo: Build fixMatteo Croce2005-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | The aironet PCI driver has a build dependency on ISA that prevent the driver to compile on systems that doesn't support ISA, like x86_64. The driver really doesn't depend on ISA, it does some ISA stuff in the initialization code, since the driver supports both ISA and PCI cards. So the driver should depend on ISA_DMA_API to build on all systems, and this will not hurt PCI at all.

* | | [PATCH] dell_rbu: changes in packet update mechanismAbhay Salunke2005-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current dell_rbu code ver 2.0 the packet update mechanism makes the user app dump every individual packet in to the driver. This adds in efficiency as every packet update makes the /sys/class/firmware/dell_rbu/loading and data files to disappear and reappear again. Thus the user app needs to wait for the files to reappear to dump another packet. This slows down the packet update tremendously in case of large number of packets. I am submitting a new patch for dell_rbu which will change the way we do packet updates; In the new method the user app will create a new single file which has already packetized the rbu image and all the packets are now staged in this file. This driver also creates a new entry in /sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet size here before downloading the packet file. The user should do the following: create one single file which has all the packets stacked together. echo the packet size in to /sys/devices/platform/dell_rbu/packet_size. echo 1 > /sys/class/firmware/dell_rbu/loading cat the packetfile > /sys/class/firmware/dell_rbu/data echo 0 > /sys/class/firmware/dell_rbu/loading The driver takes the file which came through /sys/class/firmware/dell_rbu/data and takes chunks of paket_size data from it and place in contiguous memory. This makes packet update process very efficient and fast. As all the packet update happens in one single operation. The user can still read back the downloaded file from /sys/devices/platform/dell_rbu/data.
