* Replace all uses of the vm page queues lock by a r/w lock that is privateAlan Cox2012-05-291-0/+2
| | | | | | | | | | | | | | | | to this pmap.c. This new r/w lock is used primarily to synchronize access to the TTE lists. However, it will be used in a somewhat unconventional way. As finer-grained TTE list locking is added to each of the pmap functions that acquire this r/w lock, its acquisition will be changed from write to read, enabling concurrent execution of the pmap functions with finer-grained locking.

* MFp4 bz_ipv6_fast:Bjoern A. Zeeb2012-05-241-0/+4
| | | | | | | | | | | | | | | | | | | | | | | in_cksum.h required ip.h to be included for struct ip. To be able to use some general checksum functions like in_addword() in a non-IPv4 context, limit the (also exported to user space) IPv4 specific functions to the times, when the ip.h header is present and IPVERSION is defined (to 4). We should consider more general checksum (updating) functions to also allow easier incremental checksum updates in the L3/4 stack and firewalls, as well as ponder further requirements by certain NIC drivers needing slightly different pseudo values in offloading cases. Thinking in terms of a better "library". Sponsored by: The FreeBSD Foundation Sponsored by: iXsystems Reviewed by: gnn (as part of the whole) MFC After: 3 days Notes: svn path=/head/; revision=235941

These allow boundary constraints to be fully expressed for cases where sizeof(bus_addr_t) != sizeof(bus_size_t). Specifically, it allows a driver to properly specify a 4GB boundary in a PAE kernel. Note that this cannot be safely MFC'd without a lot of compat shims due to KBI changes, so I do not intend to merge it. Reviewed by: scottl Notes: svn path=/head/; revision=232356

This solves a couple of issue regarding the non- availability of the static per-CPU data: - panic() not working and only making things worse when called, - having to supply a special DELAY() implementation to the low-level console drivers, - curthread accesses of mutex(9) usage in low-level console drivers that aren't conditional due to compiler optimizations (basically, this is the problem described in r227537 but in this case for keyboards attached via uart(4)).

* Make sparc64 compatible with NEW_PCIB and enable it:Marius Strobl2011-10-022-24/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Implement bus_adjust_resource() methods as far as necessary and in non-PCI bridge drivers as far as feasible without rototilling them. - As NEW_PCIB does a layering violation by activating resources at layers above pci(4) without previously bubbling up their allocation there, move the assignment of bus tags and handles from the bus_alloc_resource() to the bus_activate_resource() methods like at least the other NEW_PCIB enabled architectures do. This is somewhat unfortunate as previously sparc64 (ab)used resource activation to indicate whether SYS_RES_MEMORY resources should be mapped into KVA, which is only necessary if their going to be accessed via the pointer returned from rman_get_virtual() but not for bus_space(9) as the later always uses physical access on sparc64. Besides wasting KVA if we always map in SYS_RES_MEMORY resources, a driver also may deliberately not map them in if the firmware already has done so, possibly in a special way. So in order to still allow a driver to decide whether a SYS_RES_MEMORY resource should be mapped into KVA we let it indicate that by calling bus_space_map(9) with BUS_SPACE_MAP_LINEAR as actually documented in the bus_space(9) page. This is implemented by allocating a separate bus tag per SYS_RES_MEMORY resource and passing the resource via the previously unused bus tag cookie so we later on can call rman_set_virtual() in sparc64_bus_mem_map(). As a side effect this now also allows to actually indicate that a SYS_RES_MEMORY resource should be mapped in as cacheable and/or read-only via BUS_SPACE_MAP_CACHEABLE and BUS_SPACE_MAP_READONLY respectively. - Do some minor cleanup like taking advantage of rman_init_from_resource(), factor out the common part of bus tag allocation into a newly added sparc64_alloc_bus_tag(), hook up some missing newbus methods and replace some homegrown versions with the generic counterparts etc. - While at it, let apb_attach() (which can't use the generic NEW_PCIB code as APB bridges just don't have the base and limit registers implemented) regarding the config space registers cached in pcib_softc and the SYSCTL reporting nodes set up.

Removing these results a small performance improvement, specifically this is sufficient to compensate the performance loss seen in the worldstone benchmark seen when using SCHED_ULE instead of SCHED_4BSD.

| | | | | | | | | | | | | | | | | | | | | | the TLBs in order to get rid of the user mappings but instead traverse them an flush only the latter like we also do for the Spitfire-class. Also flushing the unlocked kernel entries can cause instant faults which when called from within cpu_switch() are handled with the scheduler lock held which in turn can cause timeouts on the acquisition of the lock by other CPUs. This was easily seen with a 16-core V890 but occasionally also happened with 2-way machines. While at it, move the SPARC64-V support code entirely to zeus.c. This causes a little bit of duplication but is less confusing than partially using Cheetah-class bits for these. - For SPARC64-V ensure that 4-Mbyte page entries are stored in the 1024- entry, 2-way set associative TLB. - In {d,i}tlb_get_data_sun4u() turn off the interrupts in order to ensure that ASI_{D,I}TLB_DATA_ACCESS_REG actually are read twice back-to-back.
