* When user_frac in the polling subsystem is low it is going to busy theAttilio Rao2009-05-302-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | CPU for too long period than necessary. Additively, interfaces are kept polled (in the tick) even if no more packets are available. In order to avoid such situations a new generic mechanism can be implemented in proactive way, keeping track of the time spent on any packet and fragmenting the time for any tick, stopping the processing as soon as possible. In order to implement such mechanism, the polling handler needs to change, returning the number of packets processed. While the intended logic is not part of this patch, the polling KPI is broken by this commit, adding an int return value and the new flag IFCAP_POLLING_NOCOUNT (which will signal that the return value is meaningless for the installed handler and checking should be skipped). Bump __FreeBSD_version in order to signal such situation. Reviewed by: emaste Sponsored by: Sandvine Incorporated Notes: svn path=/head/; revision=193096
* Place hostnames and similar information fully under the prison system.Jamie Gritton2009-05-291-2/+4
| | | | | | | | | | | | | | | | | | | | The system hostname is now stored in prison0, and the global variable "hostname" has been removed, as has the hostname_mtx mutex. Jails may have their own host information, or they may inherit it from the parent/system. The proper way to read the hostname is via getcredhostname(), which will copy either the hostname associated with the passed cred, or the system hostname if you pass NULL. The system hostname can still be accessed directly (and without locking) at prison0.pr_host, but that should be avoided where possible. The "similar information" referred to is domainname, hostid, and hostuuid, which have also become prison parameters and had their associated global variables removed.

* Synopsis:Sean Bruno2009-02-171-6/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If speed of link between two devices is slower than the reported max speed of both endpoints, the current driver will fail and be unable to negotiate. Summary: Test negotiated speed by reading the CSRROM into a dummy variable. If that read fails, decrement our speed and retry. If all else fails, go to lowest speed possible(0). Report speed to the user. Add display of the Bus Info Block when debug.firewire_debug > 1 Support the Bus Info Block(1394a-2000) method of speed detection. I also should note that I am moving "hold_count" to 0 for future releases. This variable determines how many bus resets to "hold" a removed firewire device before deletion. I don't feel this is useful and will probably drop support for this sysctl in the future. Reviewed by: scottl(mentor) MFC after: 2 weeks Notes: svn path=/head/; revision=188704

* Some updates and bug squashing in the firewire stack.Sean Bruno2009-02-015-69/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the interupt handler to a driver_intr_t type function as it was trying to do way to much for a lightweight filter interrupt function. Introduce much more locking around fc->mtx. Tested this for lock reversals and other such lockups. Locking seems to be working better, but there is much more to do with regard to locking. The most significant lock is in the BUS RESET handler. It was possible, before this checkin, to set a bus reset via "fwcontrol -r" and have the BUS RESET handler fire before the code responsible for asserting BUS RESET was complete. This locking fixes that issue. Move some of the memory allocations in the fc struct to the attach function in firewire.c Rework the businfo.generation indicator to be merely a on/off bit now. It's purpose according to spec is to notify the bus that the config ROM has changed. That's it. Catch and squash a possible panic in SBP where in the SBP_LOCK was held during a possible error case. The error handling code would definitely panic as it would try to acquire the SBP_LOCK on entrance. Catch and squash a camcontrol/device lockup when firewire drives go away. When a firewire device was powered off or disconnected from the firewire bus, a "camcontrol rescan all" would hang trying to poll removed devices as they were not properly detached. Don't do that.

* Step 1.5 of importing the network stack virtualization infrastructureMarko Zec2008-10-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | from the vimage project, as per plan established at devsummit 08/08: http://wiki.freebsd.org/Image/Notes200808DevSummit Introduce INIT_VNET_*() initializer macros, VNET_FOREACH() iterator macros, and CURVNET_SET() context setting macros, all currently resolving to NOPs. Prepare for virtualization of selected SYSCTL objects by introducing a family of SYSCTL_V_*() macros, currently resolving to their global counterparts, i.e. SYSCTL_V_INT() == SYSCTL_INT(). Move selected #defines from sys/sys/vimage.h to newly introduced header files specific to virtualized subsystems (sys/net/vnet.h, sys/netinet/vinet.h etc.). All the changes are verified to have zero functional impact at this point in time by doing MD5 comparision between pre- and post-change object files(*).

* Replace all calls to minor() with dev2unit().Ed Schouten2008-09-272-2/+2
| | | | | | | | | | | | | | | | | | After I removed all the unit2minor()/minor2unit() calls from the kernel yesterday, I realised calling minor() everywhere is quite confusing. Character devices now only have the ability to store a unit number, not a minor number. Remove the confusion by using dev2unit() everywhere. This commit could also be considered as a bug fix. A lot of drivers call minor(), while they should actually be calling dev2unit(). In -CURRENT this isn't a problem, but it turns out we never had any problem reports related to that issue in the past. I suspect not many people connect more than 256 pieces of the same hardware. Reviewed by: kib Notes: svn path=/head/; revision=183397
