WITH_META_MODE: Disable cookie handling for include installation.

Using a cookie with meta mode causes it to *not rerun* (as normal make
does) unless the command changes or filemon-detected files change.

After all of the work done here it turns out that skipping installation
is dangerous since the install commands use <dir>/*.h.  The actual build
command is not changing but the files installed are changing by the mere
act of adding a new header into the source tree.  Thus we cannot safely
use meta mode logic here.  It must always rerun and install the headers.

installing a header that was already present.

8 years agoAdd new bus methods for mapping resources.
jhb [Fri, 20 May 2016 17:57:47 +0000 (17:57 +0000)]
Add new bus methods for mapping resources.

Add a pair of bus methods that can be used to "map" resources for direct
CPU access using bus_space(9).  bus_map_resource() creates a mapping and
bus_unmap_resource() releases a previously created mapping.  Mappings are
described by 'struct resource_map' object.  Pointers to these objects can
be passed as the first argument to the bus_space wrapper API used for bus
resources.

Drivers that wish to map all of a resource using default settings
(for example, using uncacheable memory attributes) do not need to change.
However, drivers that wish to use non-default settings can now do so
without jumping through hoops.

First, an RF_UNMAPPED flag is added to request that a resource is not
implicitly mapped with the default settings when it is activated.  This
permits other activation steps (such as enabling I/O or memory decoding
in a device's PCI command register) to be taken without creating a
mapping.  Right now the AGP drivers don't set RF_ACTIVE to avoid using
up a large amount of KVA to map the AGP aperture on 32-bit platforms.
Once RF_UNMAPPED is supported on all platforms that support AGP this
can be changed to using RF_UNMAPPED with RF_ACTIVE instead.

Second, bus_map_resource accepts an optional structure that defines
additional settings for a given mapping.

For example, a driver can now request to map only a subset of a resource
instead of the entire range.  The AGP driver could also use this to only
map the first page of the aperture (IIRC, it calls pmap_mapdev() directly
to map the first page currently).  I will also eventually change the
PCI-PCI bridge driver to request mappings of the subset of the I/O window
resource on its parent side to create mappings for child devices rather
than passing child resources directly up to nexus to be mapped.  This
also permits bridges that do address translation to request suitable
mappings from a resource on the "upper" side of the bus when mapping
resources on the "lower" side of the bus.

Another attribute that can be specified is an alternate memory attribute
for memory-mapped resources.  This can be used to request a
Write-Combining mapping of a PCI BAR in an MI fashion.  (Currently the
drivers that do this call pmap_change_attr() directly for x86 only.)

Note that this commit only adds the MI framework.  Each platform needs
to add support for handling RF_UNMAPPED and thew new
bus_map/unmap_resource methods.  Generally speaking, any drivers that
are calling rman_set_bustag() and rman_set_bushandle() need to be
updated.

  tears down the NEW_PCIB and hotplug state including destroying
  resource managers, deleting child devices, and disabling hotplug
  events.
- Add a detach method to the ACPI PCI-PCI bridge driver which calls
  pcib_detach() and then frees the copy of the _PRT interrupt routing
  table.
- Add a detach method to the PCI-Cardbus bridge driver which frees
  the PCI bus resources in addition to calling cbb_detach().
- Explicitly clear any pending hotplug events during attach to ensure
  future events will generate an interrupt.
- If a the Command Completed bit is set in the slot status register
  when the command completion timeout fires, treat it as if the
  command completed and the completion interrupt was just lost rather
  than forcing a detach.
- Don't wait for a Command Completed notification if Command Completion
  interrupts are disabled.  The spec explicitly says no interrupt is
  enabled when clearing CCIE, and on my T400 no interrupt is generated
  when CCIE is changed from cleared to set, either.  In addition, the
  T400 doesn't appear to set the Command Completed bit in the cases
  where it doesn't generate an interrupt, so don't schedule the timer
  either.  (If the CC bit were always set, one could always set the timer

sys/vmmeter.h: Fix trivial '-Wsign-compare' warning in common header

Frankly, it doesn't make sense for vm_pageout_wakeup_thresh to have a negative
value (it is only ever set to a fraction of v_free_min, which is unsigned and
also obviously non-negative).  But I'm not going to try and convert every
non-negative scalar in the VM to unsigned today, so just cast it for the
comparison.
