* Move list types from <linux/list.h> to <linux/types.h>.Chris Metcalf2010-07-062-12/+13
| | | | | | | | | | | | | | | | This allows a list_head (or hlist_head, etc.) to be used from places that used to be impractical, in particular <asm/processor.h>, which used to cause include file recursion: <linux/list.h> includes <linux/prefetch.h>, which always includes <asm/processor.h> for the prefetch macros, as well as <asm/system.h>, which often includes <asm/processor.h> directly or indirectly. This avoids a lot of painful workaround hackery on the tile architecture, where we use a list_head in the thread_struct to chain together tasks that are activated on a particular hardwall.

* Add wait4() back to the set of <asm-generic/unistd.h> syscalls.Chris Metcalf2010-06-251-3/+6
| | | | | | | | | | | | | | | The initial pass at the generic ABI assumed that wait4() could be easily expressed using waitid(). Although it's true that wait4() can be built on waitid(), it's awkward enough that it makes more sense to continue to include wait4 in the generic syscall ABI. Since there is already a deprecated wait4 in the ABI, this change converts that wait4 into old_wait, and puts wait4 in the next available slot for new supported syscalls, after the platform-specific syscalls at number 260.

This behavior is different then the non-accelerated path and for pkts over a bonded vlan. For example, vlanx -> bond0 -> ethx will be dropped in the vlan path and not delivered to any packet handlers at all. However, bond0 -> vlanx -> ethx and bond0 -> ethx will be delivered to handlers that match the exact dev, because the VLAN path checks the real_dev which is not a slave and netif_recv_skb() doesn't drop frames but only delivers them to exact matches. This patch adds a sk_buff flag which is used for tagging skbs that would previously been dropped and allows the skb to continue to skb_netif_recv(). Here we add logic to check for the deliver_no_wcard flag and if it is set only deliver to handlers that match exactly. This makes both paths above consistent and gives pkt handlers a way to identify skbs that come from inactive slaves. Without this patch in some configurations skbs will be delivered to handlers with exact matches and in others be dropped out right in the vlan path. I have tested the following 4 configurations in failover modes and load balancing modes. # bond0 -> ethx # vlanx -> bond0 -> ethx # bond0 -> vlanx -> ethx # bond0 -> ethx | vlanx -> -- Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S.

It's actually quite simple to make that list go both ways: so that we not only can see "who uses me", but also see a list of modules that are "used by me". In fact, we always wanted that list in "module_unload_free()": when we unload a module, we want to also release all the other modules that are used by that module. But because we didn't have that list, we used to first iterate over all modules, and then iterate over each "used by me" list of that module. By making the list two-way, we simplify module_unload_free(), and it allows for some trivial fixes later too.

Add support for it. Those are the PCI ID's on this new chipset: fe:00.0 0600: 8086:2c70 (rev 02) fe:00.1 0600: 8086:2d81 (rev 02) fe:02.0 0600: 8086:2d90 (rev 02) fe:02.1 0600: 8086:2d91 (rev 02) fe:02.2 0600: 8086:2d92 (rev 02) fe:02.3 0600: 8086:2d93 (rev 02) fe:02.4 0600: 8086:2d94 (rev 02) fe:02.5 0600: 8086:2d95 (rev 02) fe:03.0 0600: 8086:2d98 (rev 02) fe:03.1 0600: 8086:2d99 (rev 02) fe:03.2 0600: 8086:2d9a (rev 02) fe:03.4 0600: 8086:2d9c (rev 02) fe:04.0 0600: 8086:2da0 (rev 02) fe:04.1 0600: 8086:2da1 (rev 02) fe:04.2 0600: 8086:2da2 (rev 02) fe:04.3 0600: 8086:2da3 (rev 02) fe:05.0 0600: 8086:2da8 (rev 02) fe:05.1 0600: 8086:2da9 (rev 02) fe:05.2 0600: 8086:2daa (rev 02) fe:05.3 0600: 8086:2dab (rev 02) fe:06.0 0600: 8086:2db0 (rev 02) fe:06.1 0600: 8086:2db1 (rev 02) fe:06.2 0600: 8086:2db2 (rev 02) fe:06.3 0600: 8086:2db3 (rev 02) (as usual, the same PCI devices repeat at ff: bus) The PCI device 8086:2c70 is shown as: fe:00.0 Host bridge: Intel Corporation QuickPath Architecture Generic Non-core Registers (rev 02) So, for this device to be recognized, it is only a matter of adding this new PCI ID to the driver.

Instead of directly probing for MC registers, it probes for another register found on Nehalem. If found, it tries to pick the first MC PCI BUS. This should work fine with Xeon 35xx, but, on Xeon 55xx, this is at bus 254 and 255 that are not properly detected by the non-legacy PCI methods. The new detection code scans specifically at buses 254 and 255 for the Xeon 55xx devices. This code has not tested yet. After working, a change at the code will be needed, since the i7core is not yet ready for working with 2 sets of MC. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Adds support for it in the hope that software error injection would work. With my tests with Xeon 35xx, there's still something missing. With a program that does sequencial bit writes at dev 0.0, sometimes, it produces error injection, after unblocking the MC_CFG_CONTROL (and, sometimes, it just locks my testing machine). I'll try later to discover by trial and error what's the register that solves this issue on Xeon 35xx. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
