* IB/mlx4: Optimize QP stampingEli Cohen2008-07-15
| | | | | | | | | | | | | | | The idea is that for QPs with fixed size work requests (eg selective signaling QPs), before stamping the WQE, we read the value of the DS field, which gives the effective size of the descriptor as used in the previous post. Then we stamp only that area, since the rest of the descriptor is already stamped. When initializing the send queue buffer, make sure the DS field is initialized to the max descriptor size so that the subsequent stamping will be done on the entire descriptor area.

* IB/sa: Fail requests made while creating new SM AHMoni Shoua2008-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch solves a race that occurs after an event occurs that causes the SA query module to flush its SM address handle (AH). When SM AH becomes invalid and needs an update it is handled by the global workqueue. On the other hand this event is also handled in the IPoIB driver by queuing work in the ipoib_workqueue that does multicast joins. Although queuing is in the right order, it is done to 2 different workqueues and so there is no guarantee that the first to be queued is the first to be executed. This causes a problem because IPoIB may end up sending an request to the old SM, which will take a long time to time out (since the old SM is gone); this leads to a much longer than necessary interruption in multicast traffer. The patch sets the SA query module's SM AH to NULL when the event occurs, and until update_sm_ah() is done, any request that needs sm_ah fails with -EAGAIN return status. For consumers, the patch doesn't make things worse. Before the patch, MADs are sent to the wrong SM so the request gets lost. Consumers can be improved if they examine the return code and respond to EAGAIN properly but even without an improvement the situation is not getting worse.

* IB/srp: Remove use of cached P_Key/GID queriesRoland Dreier2008-07-15
| | | | | | | | | | | The SRP initiator is currently using ib_find_cached_pkey() and ib_get_cached_gid() in situations where the uncached ib_find_pkey() and ib_query_gid() functions serve just as well: sleeping is allowed and performance is not an issue. Since we want to eliminate the cached operations in the long term, convert SRP to use the uncached variants. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* firmware: Correct dependency on CONFIG_EXTRA_FIRMWARE_DIRDavid Woodhouse2008-07-14
| | | | | | | | | | | When CONFIG_EXTRA_FIRMWARE_DIR gets changed, the filename in the .S file (which uses .incbin to include the binary) needs to change. When we renamed the BUILTIN_FIRMWARE_DIR option to EXTRA_FIRMWARE_DIR, we forgot to update the manual dependency in firmware/Makefile, so it was depending on a non-existent file in include/config/ Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | * ihex: Add support for long records to ihex2fw.cDavid Woodhouse2008-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some drivers could do with using records like Intel HEX, but with each record being larger than 256 bytes. This has been possible in the binary representation (struct ihex_binrec) in the kernel since the beginning -- at least of the the current version of history. But we haven't been able to represent that in the .HEX files which get converted to .fw files. This adds a '-w' option to ihex2fw to make it interpret the first _two_ bytes of each line as the record length, instead of only one byte. And adds makefile rules for %.H16->%.fw which use that.

| | * ihex: add ihex2fw tool for converting HEX files into firmware imagesDavid Woodhouse2008-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not the straight conversion to binary which objcopy can do for us, but actually representing each record with its original {addr, length}, because some drivers need that information preserved. Fix up 'firmware_install' to be able to build $(hostprogs-y) too. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| | * ihex.h: binary representation of ihex recordsDavid Woodhouse2008-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices need their firmware as a set of {address, len, data...} records in some specific order rather than a simple blob. The normal way of doing this kind of thing is 'ihex', which is a text format and not entirely suitable for use in the kernel. This provides a binary representation which is very similar, but much more compact -- and a helper routine to skip to the next record, because the alignment constraints mean that everybody will screw it up for themselves otherwise. Also a helper function which can verify that a 'struct firmware' contains a valid set of ihex records, and that following them won't run off the end of the loaded data.

| | * firmware: Add firmware installation to modules_install, add firmware_installDavid Woodhouse2008-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For 'make modules_install', install any firmware required by the modules which are being installed. Also add a 'make firmware_install' target which doesn't depend on the configuration, but installs _all_ available in-kernel-tree firmware into $(INSTALL_FW_PATH), which defaults to /lib/firmware. This is intended for distributors to make arch-independent (and config-independent) packages containing firmware. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
| | * firmware: Add CONFIG_FIRMWARE_IN_KERNEL option.David Woodhouse2008-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will control whether we build firmware into the kernel image for _every_ driver which we convert to request_firmware(), to avoid a proliferation of 'CONFIG_XXX_FIRMWARE' options for each one. Default to 'y' for now, which is the wrong thing to do but people seem to be insisting on it and refusing to even review patches until it's done.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some drivers have their own hacks to bypass the kernel's firmware loader and build their firmware into the kernel; this renders those unnecessary. Other drivers don't use the firmware loader at all, because they always want the firmware to be available. This allows them to start using the firmware loader. A third set of drivers already use the firmware loader, but can't be used without help from userspace, which sometimes requires an initrd. This allows them to work in a static kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The maestro3 driver is byte-swapping its firmware to be host-endian in advance, when it doesn't seem to be necessary -- we could just use le16_to_cpu() as we load it. Doing that means that we need to switch the in-tree firmware to be little-endian too. Take the least intrusive way of doing this, which is to switch the existing snd_m3_convert_from_le() function to convert _to_ little-endian instead, and use it on the in-tree firmware instead of the loaded firmware. It's a bit suboptimal but doesn't matter much right now because we're about to remove the special cases for the in-tree version anyway. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
