* [PATCH] 8250 UART backup timerAlex Williamson2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch below works around a minor bug found in the UART of the remote management card used in many HP ia64 and parisc servers (aka the Diva UARTs). The problem is that the UART does not reassert the THRE interrupt if it has been previously cleared and the IIR THRI bit is re-enabled. This can produce a very annoying failure mode when used as a serial console, allowing a boot/reboot to hang indefinitely until an RX interrupt kicks it into working again (ie. an unattended reboot could stall). To solve this problem, a backup timer is introduced that runs alongside the standard interrupt driven mechanism. This timer wakes up periodically, checks for a hang condition and gets characters moving again. This backup mechanism is only enabled if the UART is detected as having this problem, so systems without these UARTs will have no additional overhead. This version of the patch incorporates previous comments from Pavel and removes races in the bug detection code. The test is now done before the irq linking to prevent races with interrupt handler clearing the THRE interrupt. Short delays and syncs are also added to ensure the device is able to update register state before the result is tested. Aristeu says: this was tested on the following HP machines and solved the problem: rx2600, rx2620, rx1600 and rx1620s. hpa says: I have seen this same bug in soft UART IP from "a major vendor."

| * 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.

| * IB/mthca: Work around gcc bug on sparc64David Howells2007-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some reason gcc-3.4.5 on sparc64 does: WARNING: "____ilog2_NaN" [drivers/infiniband/hw/mthca/ib_mthca.ko] undefined! 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>

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove a superfluous initialization from the vt8231 hwmon driver; the i2c core does this, and the source field will be vanishing soon.

So I propose the following changes to that part of the driver: * Merge ali1563_enable() into ali1563_setup(). * Check the base address before the I/O space enabled bit.
