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@
2010-12-15oops, i forgot to check in the BRKSIZ define in uvm, but deraadt thinksTed Unangst
its better as a per arch MD define anyway. all default to MAXDSIZ as before.
2010-12-06- use consistent 'include' rules without a full relative path.Jasper Lievisse Adriaanse

no binary change ok deraadt@
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
2010-11-28Rename the pmap_growkernel() current limit variable from virtual_end toMiod Vallat
pmap_maxkvaddr, to mimic what other pmap_growkernel()-capable pmaps do, and to reduce confusion with what virtual_end (used to) mean.
2010-11-28Get rid of machdep.root_device sysctl and related variables.Miod Vallat
2010-11-28Do not declare a struct cfdriver and initialize it, and then write `externMiod Vallat
struct cfdriver' the bloody same struct.
2010-11-27Remove ddb single-step load and store counters. Most platforms do notMiod Vallat
implement them, and they are of questionable usefulness.
2010-11-26Disable uscanner(4) by default on all kernels which configure it. First stepMiod Vallat
until possible removal, if indeed this causes no regression for scanner users.

2010-11-20typoMiod Vallat
2010-11-20This is a first step towards getting rid of avail_start and avail_end in theMiod Vallat
kernel, currently limited to low-hanging fruit: these variables were used by bus_dma to specify the range in which to allocate memory, back when uvm_pglistalloc() was stupid and would not walk the vm_physseg[]. Nowadays, except on some platforms for early initialization, these variables are not used, or do not need to be global variables. Therefore: - remove `extern' declarations of avail_start and avail_end (or close cousins, such as arm physical_start and physical_end) from files which no longer need to use them. - make them local variables whenever possible. - remove them when they are assigned to but no longer used.

2010-09-22Revert previous and let drivers register counterless interrupts;Miod Vallat
tc_intr_disestablish() prototype is changed to carry information whether the counter needs to be detached or not. This does not matter much since no driver ever calls tc_intr_disestablish().
2010-09-22Switch to unconditionally attaching evcounts on TurboChannelMatthew Dempsky
interrupts, since inspecting the code, they seem to always attach anyway. This fixes compiler fallout from my evcount simplification. build error reported by naddy@; "seems sensible" deraadt@
2010-09-20Get rid of evcount's support for arranging counters in a treeMatthew Dempsky
hierarchy. Everything attached to a single root node anyway, so at best we had a bush. "i think it is good" deraadt@

2010-06-28Allow tty drivers to request larger buffers at attach time using aTheo de Raadt
max-baud-rate hint. Adjust TTYHOG (the nearly full logic) to this new situation. The larger buffers are required by the very high speed KDDI devices in Japan (CF com, or USB ucom) so those are the only two drivers which currently ask for a larger buffer size. ok yasuoka miod

2010-06-27uvm constraints. Add two mandatory MD symbols, uvm_md_constraintsThordur I. Bjornsson
which contains the constraints for DMA/memory allocation for each architecture, and dma_constraints which contains the range of addresses that are dma accessable by the system. This is based on ariane@'s physcontig diff, with lots of bugfixes and additions the following additions by my self: Introduce a new function pool_set_constraints() which sets the address range for which we allocate pages for the pool from, this is now used for the mbuf/mbuf cluster pools to keep them dma accessible. The !direct archs no longer stuff pages into the kernel object in uvm_km_getpage_pla but rather do a pmap_extract() in uvm_km_putpages. Tested heavily by my self on i386, amd64 and sparc64. Some tests on alpha and SGI. "commit it" beck, art, oga, deraadt "i like the diff" deraadt
2010-06-26Don't #include <sys/user.h> into files that don't need the stuffPhilip Guenthe
it defines. In some cases, this means pulling in uvm.h or pcb.h instead, but most of the inclusions were just noise. Tested on alpha, amd64, armish, hppa, i386, macpcc, sgi, sparc64, and vax, mostly by krw and naddy. ok krw@

2010-05-31Completely rewrite the tags file creation process. use config(8) againstTheo de Raadt
a fat kernel (GERERIC or GENERIC.MP) into a temporary dir, then extract some variables using make -V, and after some more singing and dancing use this full and (more) correct list of files with ctags. Don't read this code. ok guenther
