2011-04-16Use 'CLR(<buf>->b_flags, B_READ | B_WRITE | B_DONE)' regardless ofKenneth R Westerback
what the previous IO was. Less chance of copy and paste errors. Suggested by miod@.
2011-04-15More than a decade ago, interrupt handlers on sparc started returning 0Theo de Raadt
(interrupt was not for me), 1 (positive interrupt was for me), or -1 (i am not sure...). We have continued with this practice in as many drivers as possible, throughout the tree. This makes some of the architectures use that information in their interrupt handler calling code -- if 1 is returned (and we know this specific machine does not have edge-shared interrupts), we finish servicing other possible handlers on the same pin. If the interrupt pin remains asserted (from a different device), we will end up back in the interrupt servicing code of course... but this is cheaper than calling all the chained interrupts on a pin. This does of course count on shared level interrupts being properly sorted by IPL. There have been some concerns about starvation of drivers which incorrectly return 1. Those drivers should be hunted down so that they return -1. (other architectures will follow) ok kettenis drahn dlg miod
2011-04-15In days of yore one could arbitrarily whack buffer flags. Those daysKenneth R Westerback
are past. Use CLR() and SET() to modify necessary flags while leaving the flags used by the buffer cache in peace. Should make bufcache code much less confused about the state of the bufs used in reading/writing disklabels. Other such flag abuses no doubt await a visit. Errors in original diff found by miod@. ok beck@ deraadt@
2011-04-15Convert the kernel Makefiles to autogenerate dependencies during compilationPhilip Guenthe
using the -MD option to cc, with -MP, -MT, and -MF where needed, converting "make depend" to a no-op. This increases parallelism for those using "make -j" and keeps the dependencies up to date with each compilation automatically. sparc and vax users will need to rebuild gcc with support for the -M[PTF] options before config'ing with this diff.
2011-04-10A last few NULL -> 0 corrections.Miod Vallat
2011-04-09Make this compile without warnings in all modes, and do not use NULL whenMiod Vallat
integer zero is intended.
2011-04-07Do not use NULL in integer comparisons. No functional change.Miod Vallat
ok matthew@ tedu@, also eyeballed by at least krw@ oga@ kettenis@ jsg@
2011-04-06The various read*label() have stopped returning error strings for quiteMiod Vallat
some time, and return errnos instead. Fix or remove out-of-date comments mentioning the error strings, and make their callers check the return value against zero, not NULL.
2011-04-05Rename a few xbow global variable names to make them less ambiguous.Miod Vallat
Remember the hub widget number of each node, instead of only the master node. Use this in xbridge to compute the proper direct DMA map configuration register value (it needs to embed the hub widget number matching the physical address range). This should allow us to pick memory from a different node than the one we booted from, as the DMA window, if wanted.
2011-04-05Get rid of the ATE code, and do not assume the direct DMA window is set upMiod Vallat
at physical address zero onwards, but instead assume it is controlled by the dma_constraints range. This will eventually allow a different window to be selected.
2011-04-03Enable the use of all the memory found on IP27 and IP30 kernels. CommittedMiod Vallat
from an IP35 system with half its memory outside the dma_constraint range.
2011-04-03Add a consistency check for the value returned by pmap_extract() against theMiod Vallat
dma_constraints range in _dmamap_load_buffer. From and ok beck@
2011-04-03Make sure dma_constraint is listed in uvm_md_constraints[] when it does notMiod Vallat
span the whole physical address space, for the pmemrange magic to operate correctly.
2011-04-03In mtx_leave(), make sure resetting mtx_lock is the last operation on theMiod Vallat
struct mutex. Modelled after hppa.
2011-04-03Remove the `skip splraise/splx for IPL_NONE mutexes' optimizations. It is notMiod Vallat
always gaining anything, and msleep() implementation depends upon mtx_leave() invoking splx().
2011-03-23Normalize sentinel. Use _MACHINE_*_H_ and _<ARCH>_*_H_ properly and consitently.Paul Irofti
Discussed and okay drahn@. Okay deraadt@.

2011-03-13Disable write gathering on devio settings we inherit from ARCS.Miod Vallat
2011-03-13Change daddr_t to daddr32_t. The bootblocks on our architectures onlyTheo de Raadt
do 32-bit block spanning. If later on we get some that can/should do 64-bit, that can be done now using daddr64_t (but of course, we are taking this step to finalize the daddr_t 64-bit conversion). ok miod krw
2011-03-12Be more paranoid when attempting to parse an IA record, and make sure weMiod Vallat
won't try to read past the end of the record, no matter what kind of garbage it may contain. No functional change on IP35 systems with valid IA records.
2011-02-26Force the DUID cache used to generate hw.disknames to be updatedKenneth R Westerback
after every disklabel read or write. This keeps the DUID cache more in sync with the physical world. De-syncing noted by drahn@ while zapping disklabels with dd. ok jsing@ deraadt@

2010-12-30If genassym fails, sort on the pipeline will indicate no error resultingTheo de Raadt
in some grief. Split this out. From Vladimir Kirillov
2010-12-26Kill pmap_phys_address(), and force every driver's mmap() routine to returnMiod Vallat
a physical address [more precisely, something suitable to pass to pmap_enter()'sphysical address argument]. This allows MI drivers to implement mmap() routines without having to know about the pmap_phys_address() implementation and #ifdef obfuscation.
2010-12-21Convert netisr to a normal soft interrupt instead of hanving MD codeClaudio Jeker
for it. This makes the netisr a real C function which will help further development. No noticable performance change on i386 and amd64. With input from kettenis@ and miod@ additional OKs mikeb@ and henning@
2010-12-04Introduce a new pci routine, pci_conf_size(), which returns the size of aMiod Vallat
given pcitag_t configuration address space. Currently, all pci controllers will return the usual 0x100 bytes of PCI configuration space, but this will eventually change on PCIe-capable controlers. ok kettenis@

2010-12-02After the most recent change, make it possible to make -j again. TheTheo de Raadt
early MD and late MI files must be split up so that vers.o can sneak between. Issue spotted by bluhm, repair discussed with miod
2010-12-02move vers.o to before the other objects, so that it is not linked last.Theo de Raadt
having it linked last is bad (on at least i386 and amd64) because the lapic is mapped over the start of the data segment -- savecore(8) then reads the version string for a fixed buffer space, and reads into the lapic area causing unintended side-effects (at least on Intel X5570 and X5680) found by pedro, discussed with kettenis and mpf and miod
2010-11-27Missed one rbus_new_body() call in previous change.Miod Vallat
2010-11-26Disable uscanner(4) by default on all kernels which configure it. First stepMiod Vallat
