Hello, Has anybody succeded in running 3270 emulator (IBM PCOM) on wine? I tried it by copying PCOM folder from windows to fake windows directory under wine and tried below command wine "C:\Personal Communications\PCSWs.exe" Though I am not getting any error message, the program is not getting started. Can anybody please help PS : I am using Wine 20040813 which is available with

Good afternoon, I''ve two quick questions for the Ruby/Rails community. 1) Do you use Linux for Ruby or Rails development? 2) If you use Linux, which distro do you normally use to develop? Thank you for your input. :-) -- Posted via http://www.ruby-forum.com/.

I don't have any guests with PAGE_SIZE > 64k but the code seems to be clearly broken in that case as PAGE_SIZE / MERGEABLE_BUFFER_ALIGN will need more than 8 bit and so the code in mergeable_ctx_to_buf_address does not give us the actual true size.

Can someone tell me what has to happen to get the aliases working in samba? Below is an earlier posting. Thanks!! Does anyone have aliases working correctly?

Commit ab7db91705e9 ("virtio-net: auto-tune mergeable rx buffer size for improved performance") introduced a virtio-net dependency on EWMA. The inclusion of EWMA is controlled by CONFIG_AVERAGE. Fix build error when CONFIG_AVERAGE is not enabled by adding select AVERAGE to virtio-net's Kconfig entry. Build failure reported using config make ARCH=s390 defconfig. Signed-off-by:

skb_page_frag_refill currently permits only order-0 page allocs unless GFP_WAIT is used. Change skb_page_frag_refill to attempt higher-order page allocations whether or not GFP_WAIT is used. If memory cannot be allocated, the allocator will fall back to successively smaller page allocs (down to order-0 page allocs). This change brings skb_page_frag_refill in line with the existing page allocation

We are having problems joining onto our 2003 server domain. This is strange in that other linux clients on our network are NOT having problems. It appears that the domain will not allow new linux machines to join the domain, even when allowing existing machines that have the exact same configuration, to authenticate from the domain. In order to test this I have taken a stripped down debian box

Commit 2613af0ed18a ("virtio_net: migrate mergeable rx buffers to page frag allocators") changed the mergeable receive buffer size from PAGE_SIZE to MTU-size. However, the merge buffer size does not take into account the size of the virtio-net header. Consequently, packets that are MTU-size will take two buffers intead of one (to store the virtio-net header), substantially decreasing the

Sometimes we need to coalesce the rx frags to avoid frag list. One example is virtio-net driver which tries to use small frags for both MTU sized packet and GSO packet. So this patch introduce skb_coalesce_rx_frag() to do this. Cc: Rusty Russell <rusty at rustcorp.com.au> Cc: Michael S.

The virtio_net driver's mergeable receive buffer allocator uses 4KB packet buffers. For MTU-sized traffic, SKB truesize is > 4KB but only ~1500 bytes of the buffer is used to store packet data, reducing the effective TCP window size substantially. This patch addresses the performance concerns with mergeable receive buffers by allocating MTU-sized packet buffers using page frag allocators.

We need to drop the refcnt of page when we fail to allocate an skb for frag list, otherwise it will be leaked. The bug was introduced by commit 2613af0ed18a11d5c566a81f9a6510b73180660a ("virtio_net: migrate mergeable rx buffers to page frag allocators").
