* [PATCH] PCI: DMA bursting adviceDavid S. Miller2005-06-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After seeing, at best, "guesses" as to the following kind of information in several drivers, I decided that we really need a way for platforms to specifically give advice in this area for what works best with their PCI controller implementation. Basically, this new interface gives DMA bursting advice on PCI. There are three forms of the advice: 1) Burst as much as possible, it is not necessary to end bursts on some particular boundary for best performance. 2) Burst on some byte count multiple. A DMA burst to some multiple of number of bytes may be done, but it is important to end the burst on an exact multiple for best performance. The best example of this I am aware of are the PPC64 PCI controllers, where if you end a burst mid-cacheline then chip has to refetch the data and the IOMMU translations which hurts performance a lot. 3) Burst on a single byte count multiple. Bursts shall end exactly on the next multiple boundary for best performance. Sparc64 and Alpha's PCI controllers operate this way. They disconnect any device which tries to burst across a cacheline boundary. Actually, newer sparc64 PCI controllers do not have this behavior. That is why the "pdev" is passed into the interface, so I can add code later to check which PCI controller the system is using and give advice accordingly. Signed-off-by: David S.

* [PATCH] PCI: fix-pci-mmap-on-ppc-and-ppc64.patchMichael Ellerman2005-06-28
| | | | | | | | | | | | | | | | | | | | | | | This is an updated version of Ben's fix-pci-mmap-on-ppc-and-ppc64.patch which is in 2.6.12-rc4-mm1. It fixes the patch to work on PPC iSeries, removes some debug printks at Ben's request, and incorporates your fix-pci-mmap-on-ppc-and-ppc64-fix.patch also. Originally from Benjamin Herrenschmidt <benh@kernel.crashing.org> This patch was discussed at length on linux-pci and so far, the last iteration of it didn't raise any comment. It's effect is a nop on architecture that don't define the new pci_resource_to_user() callback anyway. It allows architecture like ppc who put weird things inside of PCI resource structures to convert to some different value for user visible ones. It also fixes mmap'ing of IO space on those archs.

| | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the following new interfaces for I/O xAPIC hotplug. The implementation of these interfaces depends on each architecture. o int acpi_register_ioapic(acpi_handle handle, u64 phys_addr, u32 gsi_base); This new interface is to add a new I/O xAPIC specified by phys_addr and gsi_base pair. phys_addr is the physical address to which the I/O xAPIC is mapped and gsi_base is global system interrupt base of the I/O xAPIC. acpi_register_ioapic returns 0 on success, or negative value on error. o int acpi_unregister_ioapic(acpi_handle handle, u32 gsi_base); This new interface is to remove a I/O xAPIC specified by gsi_base. acpi_unregister_ioapic returns 0 on success, or negative value on error.

* [PATCH] acpi hotplug: decouple slot power state changes from physical hotplugRajesh Shah2005-06-28
| | | | | | | | | | | | | Current acpiphp code does not distinguish between the physical presence and power state of a device/slot. That is, if a device has to be disabled, it also tries to physically ejects the device. This patch decouples power state from physical presence. You can now echo to the corresponding sysfs power control file to repeatedly enable and disable a device without having to physically re-insert it.

* [PATCH] acpi hotplug: clean up notify handlers on acpiphp unloadRajesh Shah2005-06-28
| | | | | | | | | | | | | A root bridge may not have directly attached hotpluggable slots under it. Instead, it may have p2p bridges with slots under it. In this case, we need to clean up the p2p bridges and slots properly too. Patch below applies on top of the original patch, and fixes this problem.

* [PATCH] acpi bridge hotadd: ACPI based root bridge hot-addRajesh Shah2005-06-28
| | | | | | | | | | | | | | | | | | | When you hot-plug a (root) bridge hierarchy, it may have p2p bridges and devices attached to it that have not been configured by firmware. In this case, we need to configure the devices before starting them. This patch separates device start from device scan so that we can introduce the configuration step in the middle. I kept the existing semantics for pci_scan_bus() since there are a huge number of callers to that function. Also, I have no way of testing the changes I made to the parisc files, so this needs review by those folks. Sorry for the massive cross-post, this touches files in many different places.

* [PATCH] PCI Allow OutOfRange PIRQ table addressjayalk@intworks.biz2005-06-28
| | | | | | | | | | | | | | | | | | | | | I updated this to remove unnecessary variable initialization, make check_routing be inline only and not __init, switch to strtoul, and formatting fixes as per Randy Dunlap's recommendations. I updated this to change pirq_table_addr to a long, and to add a warning msg if the PIRQ table wasn't found at the specified address, as per thread with Matthew Wilcox. In our hardware situation, the BIOS is unable to store or generate it's PIRQ table in the F0000h-100000h standard range. This patch adds a pci kernel parameter, pirqaddr to allow the bootloader (or BIOS based loader) to inform the kernel where the PIRQ table got stored. A beneficial side-effect is that, if one's BIOS uses a static address each time for it's PIRQ table, then pirqaddr can be used to avoid the $pirq search through that address block each time at boot for normal PIRQ BIOSes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: <pageexec@freemail.hu> $subject was fixed in 2.4 already, 2.6 needs it as well. The impact of the bugs is a kernel stack overflow and privilege escalation from CAP_NET_ADMIN via the IP_VS_SO_SET_STARTDAEMON/IP_VS_SO_GET_DAEMON ioctls. People running with 'root=all caps' (i.e., most users) are not really affected (there's nothing to escalate), but SELinux and similar users should take it seriously if they grant CAP_NET_ADMIN to other users.

| * [NETLINK]: Fix two socket hashing bugs.David S. Miller2005-06-26

This was causing hash->entries to underflow, which resulting in all kinds of troubles. On 64-bit systems, this would cause the following conditional to erroneously trigger: err = -ENOMEM; if (BITS_PER_LONG > 32 && unlikely(hash->entries >= UINT_MAX)) goto err; 2) netlink_autobind() needs to propagate the error return from netlink_insert(). Otherwise, callers will not see the error as they should and thus try to operate on a socket with a zero pid, which is very bad. However, it should not propagate -EBUSY. If two threads race to autobind the socket, that is fine. This is consistent with the autobind behavior in other protocols. So bug #1 above, combined with this one, resulted in hangs on netlink_sendmsg() calls to the rtnetlink socket. We'd try to do the user sendmsg() with the socket's pid set to zero, later we do a socket lookup using that pid (via the value we stashed away in NETLINK_CB(skb).pid), but that won't give us the user socket, it will give us the rtnetlink socket. So when we try to wake up the receive queue, we dive back into rtnetlink_rcv() which tries to recursively take the rtnetlink semaphore. Thanks to Jakub Jelink for providing backtraces. Also, thanks to Herbert Xu for supplying debugging patches to help track this down, and also finding a mistake in an earlier version of this fix. Signed-off-by: David S. Miller <davem@davemloft.net>

* | | [PATCH] document that 8139TOO supports 8129/8130Adrian Bunk2005-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | The 8129/8130 support is a sub-option that is not visible if the user hasn't enabled the 8139 support. Let's make it a bit easier for users to find the driver for their nic. Signed-off-by: Adrian Bunk <bunk@stusta.de>

Improvement: instead of *always* calculating lea 0x2c0(%edx),%ebx and then additionally doing the mov %edx,0xc0(%ebx) addition *if we need it*, we now do the *whole* calculation of mov %edx,0x380(%ebx) *only* if we need it. This even manages to save us a whole 16-byte alignment buffer loss in this compilation case. Result: slightly improves IRQ handler performance in both shared and non-shared IRQ case, which should make my rusty P3/700 a slight bit happier.
