2006-08-01[POWERPC] clean up pseries hcall interfacesAnton Blanchard
Our pseries hcall interfaces are out of control: plpar_hcall_norets plpar_hcall plpar_hcall_8arg_2ret plpar_hcall_4out plpar_hcall_7arg_7ret plpar_hcall_9arg_9ret Create 3 interfaces to cover all cases: plpar_hcall_norets: 7 arguments no returns plpar_hcall: 6 arguments 4 returns plpar_hcall9: 9 arguments 9 returns There are only 2 cases in the kernel that need plpar_hcall9, hopefully we can keep it that way. Pass in a buffer to stash return parameters so we avoid the &dummy1, &dummy2 madness. Signed-off-by: Anton Blanchard <anton@samba.org> -- Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-05-24[PATCH] ibmveth change buffer pools dynamicallySantiago Leon
This patch provides a sysfs interface to change some properties of the ibmveth buffer pools (size of the buffers, number of buffers per pool, and whether a pool is active). Ethernet drivers use ethtool to provide this type of functionality. However, the buffers in the ibmveth driver can have an arbitrary size (not only regular, mini, and jumbo which are the only sizes that ethtool can change), and also ibmveth can have an arbitrary number of buffer pools Under heavy load we have seen dropped packets which obviously kills TCP performance. We have created several fixes that mitigate this issue, but we definitely need a way of changing the number of buffers for an adapter dynamically. Also, changing the size of the buffers allows users to change the MTU to something big (bigger than a jumbo frame) greatly improving performance on partition to partition transfers. The patch creates directories pool1...pool4 in the device directory in sysfs, each with files: num, size, and active (which default to the values in the mainline version). Comments and suggestions are welcome... -- Santiago A. Leon Power Linux Development IBM Linux Technology Center Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-04-22[PATCH] powerpc: Quiet VETH version printkOlof Johansson
ibmveth_printk() is only used to print the driver version when the module initializes, which means on all machines as long as it's compiled in. If it's really only needed for debugging, boot with loglevel=8, or get it from dmesg instead. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-10-28[PATCH] ibmveth fix failed addbufSantiago Leon
This patch fixes a bug that happens when the hypervisor can't add a buffer. The old code wrote IBM_VETH_INVALID_MAP into the free_map array, so next time the index was used, a ibmveth_assert() caught it and called BUG(). The patch writes the right value into the free_map array so that the index can be reused. Signed-off-by: Santiago Leon <santil@us.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-10-28[PATCH] ibmveth lockless TXSantiago Leon
This patch adds the lockless TX feature to the ibmveth driver. The hypervisor has its own locking so the only change that is necessary is to protect the statistics counters. Signed-off-by: Santiago Leon <santil@us.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-10-28[PATCH] ibmveth fix buffer replenishingSantiago Leon
This patch removes the allocation of RX skb's buffers from a workqueue to be called directly at RX processing time. This change was suggested by Dave Miller when the driver was starving the RX buffers and deadlocking under heavy traffic: > Allocating RX SKBs via tasklet is, IMHO, the worst way to > do it. It is no surprise that there are starvation cases. > > If tasklets or work queues get delayed in any way, you lose, > and it's very easy for a card to catch up with the driver RX'ing > packets very fast, no matter how aggressive you make the > replenishing. By the time you detect that you need to be > "more aggressive" it is already too late. > The only pseudo-reliable way is to allocate at RX processing time. > Signed-off-by: Santiago Leon <santil@us.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-10-28[PATCH] ibmveth fix buffer pool managementSantiago Leon
This patch changes the way the ibmveth driver handles the receive buffers. The old code mallocs and maps all the buffers in the pools regardless of MTU size and it also limits the number of buffer pools to three. This patch makes the driver malloc and map the buffers necessary to support the current MTU. It also changes the hardcoded names of the buffer pool number, size, and elements to arrays to make it easier to change (with the hope of making them runtime parameters in the future).

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
