* [ALSA] ac97 - Fix silent output problem with Cx20551 codecTakashi Iwai2007-02-14
| | | | | | | | | Fixed the silent output problem on laptops with Conexant Cx20551 codec chip, such as Packard-bell EasyNote A* series. The information was taken from ALSA bug#1134. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
* [ALSA] hda-codec - Fix Oops with probing sigmatel codec chipsTakashi Iwai2007-02-14
| | | | | | | | | | When a device is unkown, the driver tries to set up the codec based on the BIOS information. Then it may result in Oops if BIOS is broken. The patch fixes the issue, falling back to a reference model in such a case. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

| | * IB/mthca: Always fill MTTs from CPUMichael S. Tsirkin2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Speed up memory registration by filling in MTTs directly when the CPU can write directly to the whole table (all mem-free cards, and to Tavor mode on 64-bit systems with the patch I posted earlier). This reduces the number of FW commands needed to register an MR by at least a factor of 2 and speeds up memory registration significantly. Signed-off-by: Michael S.

| | * IB/mthca: Merge MR and FMR space on 64-bit systemsMichael S. Tsirkin2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For Tavor, we currently reserve separate MPT and MTT space for FMRs to avoid abusing the vmalloc space on 32 bit kernels. No such problem exists on 64 bit kernels so let's not do it there. This way we have a shared pool for MR and FMR resources, used on demand. This will also make it possible to write MTTs for regular regions directly from driver. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
| | * IB/mthca: Fix access to MTT and MPT tables on non-cache-coherent CPUsMichael S. Tsirkin2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We allocate the MTT table with alloc_pages() and then do pci_map_sg(), so we must call pci_dma_sync_sg() after the CPU writes to the MTT table. This works since the device will never write MTTs on mem-free HCAs, once we get rid of the use of the WRITE_MTT firmware command. This change is needed to make that work, and is an improvement for now, since it gives FMRs a chance at working. For MPTs, both the device and CPU might write there, so we must allocate DMA coherent memory for these. Signed-off-by: Michael S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | MTTs are allocated in non-cache-coherent memory, so we must give reserved MTTs their own cache line, to prevent both device and CPU from writing into the same cache line at the same time.

| | * IB/mthca: Work around gcc bug on sparc64David Howells2007-02-10

Points to note: (1) The asm volatile flush/flushw are just markers for viewing what comes out in the assembly; removing them has no effect on the result. (2) Changing almost anything else in dwh__mthca_arbel_init_srq_context() or dwh__mthca_alloc_srq() causes the problem to go away. The compiler command line issued by the kernel build is: /opt/crosstool/gcc-3.4.5-glibc-2.3.6/sparc64-unknown-linux-gnu/bin/sparc64-unknown-linux-gnu-gcc -fno-strict-aliasing -fno-common -Os -m64 -mno-fpu -mcpu=ultrasparc -mcmodel=medlow -ffixed-g4 -ffixed-g5 -fcall-used-g7 -Wa,--undeclared-regs -pg -fno-omit-frame-pointer -fno-optimize-sibling-calls -fasynchronous-unwind-tables -g -c -o drivers/infiniband/hw/mthca/.tmp_mthca_srq.o drivers/infiniband/hw/mthca/mthca_srq.c This can be reduced to this whilst still retaining the problem: /opt/crosstool/gcc-3.4.5-glibc-2.3.6/sparc64-unknown-linux-gnu/bin/sparc64-unknown-linux-gnu-gcc -m64 -c -o drivers/infiniband/hw/mthca/mthca_srq.o drivers/infiniband/hw/mthca/mthca_srq.c -Os Removing -Os or changing it to -O or -O0 thru -O6 gets rid of the problem.

| | * IPoIB: Connected mode experimental supportMichael S. Tsirkin2007-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch adds experimental support for IPoIB connected mode, as defined by the draft from the IETF ipoib working group. The idea is to increase performance by increasing the MTU from the maximum of 2K (theoretically 4K) supported by IPoIB on top of UD. With this code, I'm able to get 800MByte/sec or more with netperf without options on a Mellanox 4x back-to-back DDR system. Some notes on code: 1. SRQ is used for scalability to large cluster sizes 2. Only RC connections are used (UC does not support SRQ now) 3. Retry count is set to 0 since spec draft warns against retries 4. Each connection is used for data transfers in only 1 direction, so each connection is either active(TX) or passive (RX). 2 sides that want to communicate create 2 connections. 5. Each active (TX) connection has a separate CQ for send completions - this keeps the code simple without CQ resize and other tricks 6. To detect stale passive side connections (where the remote side is down), we keep an LRU list of passive connections (updated once per second per connection) and destroy a connection after it has been unused for several seconds. The LRU rule makes it possible to avoid scanning connections that have recently been active. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

At the same time, TCP may have rcv_wnd (32-bits) that does not fit to 16-bits without window scaling resulting in pseudo garbage into advertized window from the low-order bits of rcv_wnd. This can happen at least when mss <= (1<<wscale) (see tcp_select_initial_window). This patch fixes the handling of SYN advertized windows (compile tested only). In worst case (which is unlikely to occur though), the receiver advertized window could be just couple of bytes. I'm not sure that such situation would be handled very well at all by the receiver!? Fortunately, the situation normalizes after the first non-SYN ACK is received because it has the correct, scaled window. Alternatively, tcp_select_initial_window could be changed to prevent too large rcv_wnd in the first place.

This function is not called on 32-bit, however if btext early debug is enabled it does have an explicit, inline, #ifdef-ed assignment performing analagous initialization. This patch makes things more uniform by folding the btext initialization as an option into udbg_early_init() and calling that from the 32-bit setup path.

It will automatically take over devices that come from the legacy serial detection, which usually is only one device. In some cases, rtas may be set up to use the serial port in the firmware, which allows easier debugging before probing the serial ports. In this case, the "used-by-rtas" property must be set by the firmware. This patch also adds code to the legacy serial driver to check for this.

This is well and truly early enough to cause no change in behaviour, we can't kexec until userspace has given us a kernel to kexec into.

This gives us a convenient place to put things that need to be available to the platform code, but not public. And hopefully will help people resist the temptation of sticking externs in C files.
