* [netdrvr] b44: handle excessive multicast groupsJeff Garzik2006-10-05
| | | | | | | | | | | | | If there are more than B44_MCAST_TABLE_SIZE groups in the dev->mc_list, it will only listen to the first B44_MCAST_TABLE_SIZE that it sees. This change makes the driver go into RXCONFIG_ALLMULTI mode if there are more than B44_MCAST_TABLE_SIZE groups being subscribed to, similar to other network drivers.

* [PATCH] bonding: fix deadlock on high loads in bond_alb_monitor()Karsten Keil2006-10-05
| | | | | | | | | | | | | | In bond_alb_monitor the bond->curr_slave_lock write lock is taken and then dev_set_promiscuity maybe called which can take some time, depending on the network HW. If a network IRQ for this card come in the softirq handler maybe try to deliver more packets which end up in a request to the read lock of bond->curr_slave_lock -> deadlock. This issue was found by a test lab during network stress tests, this patch disable the softirq handler for this case and solved the issue.

* [PATCH] ibmveth: fix int rollover panicSantiago Leon2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a nasty bug that has been sitting there since the very first versions of the driver, but is generating a panic because we changed the number of 2K buffers for 2.6.16. The consumer_index and producer_index are u32's that get incremented on every buffer emptied and replenished respectively. We use the {producer,consumer}_index mod'ed with the size of the pool to pick out an entry in the free_map. The problem happens when the u32 rolls over and the number of the buffers in the pool is not a perfect divisor of 2^32. i.e. if the number of 2K buffers is 0x300, before the consumer_index rolls over, our index to the free map = 0xffffffff mod 0x300 = 0xff. The next time a buffer is emptied, we want the index to the free map to be 0x100, but 0x0 mod 0x300 is 0x0. This patch assigns the mod'ed result back to the consumer and producer indexes so that they never roll over. The second chunk of the patch covers the unlikely case where the consumer_index has just been reset to 0x0 and the hypervisor is not able to accept that buffer.

* [PATCH] ibmveth: rename proc entry nameSantiago Leon2006-10-05
| | | | | | | | | | | | | | This patch changes the name of the proc file for each ibmveth adapter from the network device name to the slot number in the virtual bus. The proc file is created when the device is probed, so a change in the name of the device will not be reflected in the name of the proc file giving problems when identifying and removing the adapter. The slot number is a property that does not change through the life of the adapter so we use that instead.

* [PATCH] ibmveth: kdump interrupt fixSantiago Leon2006-10-05
| | | | | | | | | | | | | | | This patch fixes a race that panics the kernel when opening the device after a kdump. Without this patch there is a window where the hypervisor can send an interrupt before all the structures for the kdump ibmveth module are ready (because the hypervisor is not aware that the partition crashed and that the virtual driver is reloading). We close this window by disabling the interrupts before registering the adapter to the hypervisor. This patch depends on the "ibmveth: Harden driver initilisation" patch.

This was originally meant for use by oprofile, but is now also used by the GNU debugger, if available. In order for oprofile to find the location in an spu-elf binary where an event counter triggered, we need a way to identify the binary in the first place. Unfortunately, that binary itself can be embedded in a powerpc ELF binary. Since we can assume it is mapped into the effective address space of the running process, have that one write the pointer value into a new spufs file. When a context switch occurs, pass the user value to the profiler so that can look at the mapped file (with some care).

This adds support for a more conventional format using 'interrupts' and 'reg' properties. The interrupts are specified in three cells (class 0, 1 and 2) and registered at the interrupt-parent. The reg property contains either three or four register areas in the order 'local-store', 'problem', 'priv2', and 'priv1', so the priv1 one can be left out in case of hypervisor driven systems that access these through hcalls.

If the spu application keeps writing to its outbound mailbox, the read call will pick up all the data in a single system call. Unfortunately, if the user passes an invalid pointer, we may lose a mailbox element on read, since we can't put it back. This probably impossible to solve, if the user also accesses the mailbox through direct register access.

| * | [POWERPC] spufs: use correct pg_prot for mapping SPU local storeArnd Bergmann2006-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This hopefully fixes a long-standing bug in the spu file system. An spu context comes with local memory that can be either saved in kernel pages or point directly to a physical SPE. When mapping the physical SPE, that mapping needs to be cache-inhibited. For simplicity, we used to map the kernel backing memory that way too, but unfortunately that was not only inefficient, but also incorrect because the same page could then be accessed simultaneously through a cacheable and a cache-inhibited mapping, which is not allowed by the powerpc specification and in our case caused data inconsistency for which we did a really ugly workaround in user space.

So far, this has no impact whatsover on scheduling, but makes it possible to add that later. A new type of object in spufs is now a spu_gang. It is created with the spu_create system call with the flags argument set to SPU_CREATE_GANG (0x2). Inside of a spu_gang, it is then possible to create spu_context objects, which until now was only possible at the root of spufs. There is a new member in struct spu_context pointing to the spu_gang it belongs to, if any. The spu_gang maintains a list of spu_context structures that are its children. This information can then be used in the scheduler in the future. There is still a bug that needs to be resolved in this basic infrastructure regarding the order in which objects are removed. When the spu_gang file descriptor is closed before the spu_context descriptors, we leak the dentry and inode for the gang. Any ideas how to cleanly solve this are appreciated.

Fortunately, libspe has never been using the returned contents of that register, as they were the same as the return code of spu_run (duh!). Unlike the specification that we never implemented correctly, we now require a SPU_CREATE_EVENTS_ENABLED flag passed to spu_create, in order to get the new behavior. When this flag is not passed, spu_run will simply ignore the third argument now. Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

There can be a quite large time gap between 2) and 3) and I found the following problem: Between 2) and 3) If the context becomes unbound, 3) is not executed because when the spe-manager thread is awaken, the context is already saved. (This situation can happen, for example, when a high priority spe thread newly started in that time gap) But the actual problem is that the corresponding SPU context does not work even if it is bound again to a SPU. Besides I can see the following warning in mambo simulator when the context becomes unbound(in save_mfc_cmd()), i.e. when unbind() is called for the context after step 2) before 3) : 'WARNING: 61392752237: SPE2: MFC_CMD_QUEUE channel count of 15 is inconsistent with number of available DMA queue entries of 16' After I go through available documents, I found that the problem is because the suspended DMA is not restarted when it is bound again.

The new arch/powerpc/platforms/cell/spufs/sched.c is greatly simplified, in an attempt to reduce complexity while adding support for NUMA scheduler domains. SPUs are allocated starting from the calling thread's node, moving to others as supported by current->cpus_allowed. Preemption is gone as it was buggy, but should be re-enabled in another patch when stable. The new arch/powerpc/platforms/cell/spu_base.c maintains idle lists on a per-node basis, and allows caller to specify which node(s) an SPU should be allocated from, while passing -1 tells spu_alloc() that any node is allowed. Since the patch removes the currently implemented preemptive scheduling, it is technically a regression, but practically all users have since migrated to this version, as it is part of the IBM SDK and the yellowdog distribution, so there is not much point holding it back while the new preemptive scheduling patch gets delayed further.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new "psmap" file to spufs that allows mmap of all of the problem state mapping of SPEs. It is compatible with 64k pages. In addition, it removes mmap ability of individual files when using 64k pages, with the exception of signal1 and signal2 which will both map the entire 64k page holding both registers. It also removes CONFIG_SPUFS_MMAP as there is no point in not building mmap support in spufs. It goes along a separate patch to libspe implementing usage of that new file to access problem state registers. Another patch will follow up to fix races opened up by accessing the 'runcntl' register directly, which is made possible with this patch.

| * [SCSI] SCSI st: fix error handling in module init, sysfsJeff Garzik2006-10-04
| | | | | | | | | | | | | | | | | | | | | | - Notice and handle sysfs errors in module init, tape init - Properly unwind errors in module init - Remove bogus st_sysfs_class==NULL test, it is guaranteed !NULL at that point Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
| * [SCSI] SCSI sd: fix module init/exit error handlingJeff Garzik2006-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Properly handle and unwind errors in init_sd(). Fixes leaks on error, if class_register() or scsi_register_driver() failed. - Ensure that exit_sd() execution order is the perfect inverse of initialization order. FIXME: If some-but-not-all register_blkdev() calls fail, we wind up calling unregister_blkdev() for block devices we did not register. This was a pre-existing bug.

| * [SCSI] SCSI osst: add error handling to module init, sysfsJeff Garzik2006-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - check all sysfs-related return codes, and propagate them back to callers - properly unwind errors in osst_probe(), init_osst(). This fixes a leak that occured if scsi driver registration failed, and fixes an oops if sysfs creation returned an error. (unrelated) - kzalloc() cleanup in new_tape_buf() Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
