problems with netback
hi
I've some problems with netback
1.what's mmap_pages for, which come from balloon operation ？
mmap_pages = alloc_empty_pages_and_pagevec(MAX_PENDING_REQS)
2.what's the meaning of "refcnt" defined in netif_t (netif->refcnt)
3.irq enable and disable
such as disable_irq(netif->irq);
why netback use such enable & disable operations while netfront dont use for its irq?
4.blank "resume" operation for netback
why netfront has "resueme" defined, while not in netback?
which event will result in calling the "resume" function?
thanks...

[PATCH] Handle MSI irq storm
<<handle_msi_irq_storm.patch>> Hi, Keir,
This patch handles MSI irq storm. Unluckily, I have observed this
phenomenon again. This will happen when some kind of MSI-X capable NIC
is assigned to an HVM guest. The basic idea is to mask the interrupt on
receiving the second interrupt and set a timer to unmask after 1ms.
Can you have a look and give some comments on that? Thanks!
Best

Xen PVM: Strange lockups when running PostgreSQL load
I am currently looking at a bug report[1] which is happening when
a Xen PVM guest with multiple VCPUs is running a high IO database
load (a test script is available in the bug report).
In experimenting it seems that this happens (or is getting more
likely) when the number of VCPUs is 8 or higher (though I have
not tried 6, only 2 and 4), having autogroup enabled seems to
make it more likely, too

[PATCH v2 00/21] drm: Clean up VBLANK callbacks in struct drm_driver
VBLANK handlers in struct drm_driver are deprecated. Only legacy,
non-KMS drivers are supposed to used them. DRM drivers with kernel
modesetting are supposed to use VBLANK callbacks of the CRTC
infrastructure.
This patchset converts all DRM drivers to CRTC VBLANK callbacks and
cleans up struct drm_driver. The remaining VBLANK callbacks in struct
drm_driver are only used by legacy drivers.
