2013-08-12Upcoming radeondrm(4) support will grow the kernel. This growth causes theMark Kettenis
linker to merge ithe .text and .data sections, even though there is no reason why it should do this. Leave more space between these sections to keep the linker from doing this.
2013-08-12Add a port of the TTM and Radeon DRM code from Linux 3.8.13.Jonathan Gray
Includes kernel modesetting, framebuffer console and support for newer hardware. Firmware needs to be present for acceleration and in some cases modesetting to work. It can be installed via fw_update or manually via pkg_add. With lots of help from kettenis@ some macppc bits from mpi@ and some ttm refcount/queue bits from FreeBSD. Thanks to M:Tier and the OpenBSD Foundation for sponsoring this work.

2013-07-16Enable jfb-style acceleration on XVR-600.Miod Vallat
2013-07-16Add support for BUS_INTR_ESTABLISH_MPSAFE. This makes the previous commitMark Kettenis
to vcons(4) actually have an effect.
2013-07-16The interrupt handler for vcons(4) is defenitely safe to run without holdingMark Kettenis
the kernel lock, so use BUS_INTR_ESTABLISH_MPSAFE.
2013-07-16Add support for BUS_INTR_ESTABLISH_MPSAFE.Mark Kettenis
2013-07-15Use getpropstringA(), not getpropstring(), to get the card's name. This ensuresMiod Vallat
its value has not been clobbered when ifb_accel_identify() is invoked, and restores textmode acceleration on Expert3D{,-Lite} and XVR-1200. Broken since 1.17, sigh
2013-07-14To prevent lock ordering problems with the kernel lock, we need to make sureMark Kettenis
we block all interrupts that can grab the kernel lock. The simplest way to achieve this is to make sure mutexes always raise the ipl to the highest level that has interrupts that grab the kernel lock. This will allow us to have "mpsafe" interrupt handlers at lower priority levels. No change for non-MULTIPROCESSOR kernels.

2013-06-23Stop using -traditional-cpp on gcc3/4 platforms.Miod Vallat
Add CWARNFLAGS to the command line when using -xassembler-with-cpp. We are mostly interested in -Werror here.
2013-06-15Stop handling overlapping copies in memcpy() by jumping straight into theMark Kettenis
forward copy path.
2013-06-13Remove a remnant of the VIS optimized bcopy code that was hiding in a delayMark Kettenis
slot.
2013-06-13Get rid of the VIS-optimized bcopy/bzero code. This has never been enabled,Mark Kettenis
but did get compiled in. Made locore.s even more intimidating. ok deraadt@

No binary change.

2013-06-01cleanup and consolidate the spinlock_lock (what a name!) code.Ted Unangst
it's now atomic_lock to better reflect its usage, and librthread now features a new spinlock that's really a ticket lock. thrlseep can handle both types of lock via a flag in the clock arg. (temp back compat hack) remove some old stuff that's accumulated along the way and no longer used. some feedback from dlg, who is concerned with all things ticket lock. (you need to boot a new kernel before installing librthread)

2013-05-17Implement IPL_MPSAFE for pci bus interrupt handlers.Mark Kettenis
2013-05-16Run audio interrupts without grabbing the kernel lock. While IPL_SERIAL isMark Kettenis
higher than IPL_AUDIO on sparc64, and interrupt handlers running at IPL_SERIAL still grab the kernel lock, this isn't a problem as machines with audioce(4) are guaranteed not to have zs(4) (the only driver that uses IPL_SERIAL).
2013-05-15Introduce a global interrupt-aware mutex protecting dataAlexandre Ratchov
structures (including sound-card registers) from concurent access by syscall and interrupt code-paths. Since critical sections remain the same, calls to splraise/spllower can be safely replaced by calls to mtx_enter/mtx_leave with two exceptions: (1) mutexes are not reentrant (the inner splraise is thus removed), and (2) we're not allowed to sleep with a mutex (either msleep is used or the mutex is released before sleeping). ok and help from kettenis, a lot of work from armani
2013-05-13Get rid of some silly underscores.Mark Kettenis
2013-05-13Implement support for running interrupt handlers without taking the kernelMark Kettenis
lock, by adding a new BUS_INTR_ESTABLISH_MPSAFE flag for use with the (sparc64-specific) bus_intr_establish(9) interface. Add support for this flag to schizo(4); other bus drivers will ignore it for now. While there, remove the BUS_INTR_ESTABLISH_FASTTRAP flag which serves no purpose.

2013-05-12Take the kernel lock and call the actual interrupt handler from aMark Kettenis

Most of the hard work by mpi@, who provided the initial diff. Fixes for sparc from myself. Tested on sgi and sparc myself. Compiles and detects zstty on my powerbook, compile tested on sparc64 by me. Real testing with zs device on sparc64 by miod@ who also gave a lot of help and feedback. ok miod@, mpi@
2013-04-02Get rid of SYSCALL_G7RFLAG. iIt's been deprecated for a long time already,Mark Kettenis
and we've started using %g7 as a per-thread register now. If you have any binaries left that use this flag they'll probably crash and burn!
2013-04-01Do not expose the trap T_* values to userland, since they invade theTheo de Raadt
namespace a bit much. These are the names for the value encoded in core.c_ucode or siginfo.si_trapno, but userland never looks directly and only cares about the abstract signal code. ok guenther

to keep definitions our of user space. The MD files now follow a consistant order -- all namespace intrusion is at the tail can be cleaned up independently. locore, bootblocks, and libkvm still see enough visibility to build. Checked on 90% of platforms...
