| | | | | | | | | | | | | | | | resource allocation from an x86 Host-PCI bridge driver so that it can be reused by the ACPI Host-PCI bridge driver (and eventually the MPTable Host-PCI bridge driver) instead of duplicating the same logic. Note that this means that hw.acpi.host_mem_start is now replaced with the hw.pci.host_mem_start tunable that was already used in the non-ACPI case. This also removes hw.acpi.host_mem_start on ia64 where it was not applicable (the implementation was very x86-specific). While here, adjust the logic to apply the new start address on any "wildcard" allocation even if that allocation comes from a subset of the allowable address range. Reviewed by: imp (1)

* Enable sound support by default on i386 and amd64.joel2011-06-111-0/+8
| | | | | | | | | | | | | | | | | The generic sound driver has been added, along with enough device-specific drivers to support the most common audio chipsets. We've discussed enabling it from time to time over the years and we've received numerous requests from users, so we decided that shipping 9.0 with working audio by default would be the best thing to do. Bug reports should be sent to the multimedia@ mailing list, as usual. Approved by: mav No objection: re

* remove code for dynamic offlining/onlining of CPUs on x86avg2011-06-083-169/+10
| | | | | | | | | | | | | | | | | | | | | | | The code has definitely been broken for SCHED_ULE, which is a default scheduler. It may have been broken for SCHED_4BSD in more subtle ways, e.g. with manually configured CPU affinities and for interrupt devilery purposes. We still provide a way to disable individual CPUs or all hyperthreading "twin" CPUs before SMP startup. See the UPDATING entry for details. Interaction between building CPU topology and disabling CPUs still remains fuzzy: topology is first built using all availble CPUs and then the disabled CPUs should be "subtracted" from it. That doesn't work well if the resulting topology becomes non-uniform. This work is done in cooperation with Attilio Rao who in addition to reviewing also provided parts of code.

Now the driver actively manages the I/O windows. This is implemented by allocating a bus resource for each I/O window from the parent PCI bus and suballocating that resource to child devices. The suballocations are managed by creating an rman for each I/O window. The suballocated resources are mapped by passing the bus_activate_resource() call up to the parent PCI bus. Windows are grown when needed by using bus_adjust_resource() to adjust the resource allocated from the parent PCI bus. If the adjust request succeeds, the window is adjusted and the suballocation request for the child device is retried. When growing a window, the rman_first_free_region() and rman_last_free_region() routines are used to determine if the front or end of the existing I/O window is free. From using that, the smallest ranges that need to be added to either the front or back of the window are computed. The driver will first try to grow the window in whichever direction requires the smallest growth first followed by the other direction if that fails. Subtractive bridges will first attempt to satisfy requests for child resources from I/O windows (including attempts to grow the windows). If that fails, the request is passed up to the parent PCI bus directly however. The PCI-PCI bridge driver will try to use firmware-assigned ranges for child BARs first and only allocate a "fresh" range if that specific range cannot be accommodated in the I/O window. This allows systems where the firmware assigns resources during boot but later wipes the I/O windows (some ACPI BIOSen are known to do this) to "rediscover" the original I/O window ranges. The ACPI Host-PCI bridge driver has been adjusted to correctly honor hw.acpi.host_mem_start and the I/O port equivalent when a PCI-PCI bridge makes a wildcard request for an I/O window range. The new PCI-PCI bridge driver is only enabled if the NEW_PCIB kernel option is enabled. This is a transition aide to allow platforms that do not yet support bus_activate_resource() and bus_adjust_resource() in their Host-PCI bridge drivers (and possibly other drivers as needed) to use the old driver for now. Once all platforms support the new driver, the kernel option and old driver will be removed. PR: kern/143874 kern/149306 Tested by: mav

That is going to offer the underlying support for a simple bump of MAXCPU and then support for number of cpus > 32 (as it is today). Right now, cpumask_t is an int, 32 bits on all our supported architecture. cpumask_t on the other side is implemented as an array of longs, and easilly extendible by definition. The architectures touched by this commit are the following: - amd64 - i386 - pc98 - arm - ia64 - XEN while the others are still missing. Userland is believed to be fully converted with the changes contained here. Some technical notes: - This commit may be considered an ABI nop for all the architectures different from amd64 and ia64 (and sparc64 in the future) - per-cpu members, which are now converted to cpuset_t, needs to be accessed avoiding migration, because the size of cpuset_t should be considered unknown - size of cpuset_t objects is different from kernel and userland (this is primirally done in order to leave some more space in userland to cope with KBI extensions). If you need to access kernel cpuset_t from the userland please refer to example in this patch on how to do that correctly (kgdb may be a good source, for example). - Support for other architectures is going to be added soon - Only MAXCPU for amd64 is bumped now The patch has been tested by sbruno and Nicholas Esborn on opteron 4 x 12 pack CPUs. More testing on big SMP is expected to came soon. pluknet tested the patch with his 8-ways on both amd64 and i386. Tested by: pluknet, sbruno, gianni, Nicholas Esborn Reviewed by: jeff, jhb, sbruno

| | | | | | | | | | | | | | NFS client (which I guess is no longer experimental). The fstype "newnfs" is now "nfs" and the regular/old NFS client is now fstype "oldnfs". Although mounts via fstype "nfs" will usually work without userland changes, an updated mount_nfs(8) binary is needed for kernels built with "options NFSCL" but not "options NFSCLIENT". Updated mount_nfs(8) and mount(8) binaries are needed to do mounts for fstype "oldnfs". The GENERIC kernel configs have been changed to use options NFSCL and NFSD (the new client and server) instead of NFSCLIENT and NFSSERVER. For kernels being used on diskless NFS root systems, "options NFSCL" must be in the kernel config. Discussed on freebsd-fs@.
