This updates the DMA API documentation to address a few issues: - The dma_map_sg() call results are used like pci_map_sg() results: using sg_dma_address() and sg_dma_len(). That's not wholly obvious to folk reading _only_ the "new" DMA-API.txt writeup. - Buffers allocated by dma_alloc_coherent() may not be completely free of coherency concerns ... some CPUs also have write buffers that may need to be flushed. - Cacheline coherence issues are now mentioned as being among issues which affect dma buffers, and complicate/prevent using of static and (especially) stack based buffers with the DMA calls. I don't think many drivers currently need to worry about flushing write buffers, but I did hit it with one SOC using external SDRAM for DMA descriptors: without explicit writebuffer flushing, the on-chip DMA controller accessed descriptors before the CPU completed the writes.

I use 2.6.15.6 Linux kernel and found some problems. I have about 100 Linux boxes (all with the same (binary the same) kernel). Last time I have upgraded all those boxes from 2.4.32 to 2.6.15.6 (first 2.6.15.1, next .2, .4 and .6) and I have found some problems on VIA based PC's. Probably the reason of this is that some VIA chipsets are unrecognized by IRQ router. In line 586 there is: /* FIXME: add new ones for 8233/5 */ There were only a few of chipsets ID's there, some of my VIA chipsets were not present and kernel used default IRQ router. I have added three entries, so that the code looks like: case PCI_DEVICE_ID_VIA_82C596: case PCI_DEVICE_ID_VIA_82C686: case PCI_DEVICE_ID_VIA_8231: case PCI_DEVICE_ID_VIA_8233A: case PCI_DEVICE_ID_VIA_8235: case PCI_DEVICE_ID_VIA_8237: case PCI_DEVICE_ID_VIA_8237_SATA: /* FIXME: add new ones for 8233/5 */ r->name = "VIA"; r->get = pirq_via_get; r->set = pirq_via_set; return 1; } The kernel goes fine but I haven't testes it for weeks, I'm just a moment after reboot :) One thing is different (better?): Using previus kernel I had: PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 0 now I have: PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 11 Maybe it is good idea to add there some more VIA chipsets? The ones I have added seem to be OK. From: Grzegorz Janoszka <Grzegorz@Janoszka.pl> Acked-by: Martin Mares <mj@ucw.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

The init function for the RPA PCI Hotplug driver returns -ENODEV in the case that no hotplug-capable slots are detected in the system. This is bad, since hot-capable slots can be added after boot to a purely virtual POWER partition. This is also bad because DLPAR I/O operations depend on the rpaphp module. Change the rpaphp init module to return success for the case of partitions that own no hotplug-capable slots at boot. Such slots can be dynamically added after boot.

Sparse warns about casting to a __bitwise type. However, it's correct to do when defining the enum for pci_bus_flags_t, so add a __force to quiet the warnings.

The naming of the constant defined for PCI ID 1022:7450 does not seem to match the information at http://pciids.sourceforge.net/: http://pci-ids.ucw.cz/iii/?i=1022 There 1022:7450 is listed as "AMD-8131 PCI-X Bridge" while 1022:7451 is listed as "AMD-8131 PCI-X IOAPIC". Yet, the current definition for 0x7450 is PCI_DEVICE_ID_AMD_8131_APIC. It seems to me like that name should map to 0x7451, while a name like PCI_DEVICE_ID_AMD_8131_BRIDGE should map to 0x7450.

This is two distinct changes. - Not changing our real parents. - Not changing our ptrace parents. Not changing our real parents is trivially correct because both tasks have the same real parents as they are part of a thread group. Now that we demote the leader to a thread there is no longer any reason to change it's parentage. Not changing our ptrace parents is a user visible change if someone looks hard enough. I don't think user space applications will care or even notice. In the practical and I think common case a debugger will have attached to all of the threads using the same ptrace flags. From my quick skim of strace and gdb that appears to be the case. Which if true means debuggers will not notice a change. Before this point we have already generated a ptrace event in do_exit that reports the leaders pid has died so de_thread is visible to a debugger. Which means attempting to hide this case by copying flags around appears excessive. By not doing anything it avoids all of the weird locking issues between de_thread and ptrace attach, and removes one case from consideration for fixing the ptrace locking. This only addresses Oleg's first concern with ptrace_attach, that of the problems caused by reparenting. Oleg's second concern is essentially a race between ptrace_attach and release_task that causes an oops when we get to force_sig_specific. There is nothing special about de_thread with respect to that race. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Robin Holt authored
This patch modifies ia64's show_mem() to walk the vmem_map page tables and rapidly skip forward across regions where the page tables are missing. This prevents the pfn_valid() check from causing numerous unnecessary page faults. Without this patch on a 512 node 512 cpu system where every node has four memory holes, the show_mem() call takes 1 hour 18 minutes. With this patch, it takes less than 3 seconds.

ia64_wait_for_slaves() was changed in 2.6.17-rc1 to report the slave state. It incorrectly assumes that all slaves are for MCA, but ia64_wait_for_slaves() is also called from the INIT monarch handler. The existing message is very misleading, so correct it.

By calling send_sig do_SAK is recursively taking the tasklist_lock, which is silly. In addition I just audited the kernel and this was the only place where tasklist_lock is taken inside of task_lock. So this one line change is a general worthwhile cleanup and it increases our options on how to fix the ptrace_attach races. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

After resetting the hardware on a tx_timeout, call netif_wake_queue() only if we have free tx descriptors. Also, attempt to recover if mv643xx_eth_start_xmit() is called when there are fewer free tx descriptors than expected. The BUG_ON() call we are replacing was hit on a tx_timeout that called netif_wake_queue(), indirectly via netif_device_attach(), even though we did not have enough free tx descriptors.

The driver allocates SRQ WQEs size with a power of 2 size both for Tavor and for memfree. For Tavor, however, the hardware only requires the WQE size to be a multiple of 16, not a power of 2, and the max number of scatter-gather allowed is reported accordingly by the firmware (and this is the value currently returned by ib_query_device() and ibv_query_device()). If the max number of scatter/gather entries reported by the FW is used when creating an SRQ, the creation will fail for Tavor, since the required WQE size will be increased to the next power of 2, which turns out to be larger than the device permitted max WQE size (which is not a power of 2). This patch reduces the reported SRQ max wqe size so that it can be used successfully in creating an SRQ on Tavor HCAs.
