2007-01-08i915: Fix a DRM_ERROR that should be DRM_DEBUG.=?utf-8?q?Michel_D=C3=A4nzer?=
It would clutter up the kernel output in a situation which is legitimate before X.org 7.2 and handled correctly by the 3D driver. Signed-off-by: Dave Airlie <airlied@linux.ie>

2006-12-15drm: Unify radeon offset checking.=?utf-8?q?Michel_D=C3=A4nzer?=
Replace r300_check_offset() with generic radeon_check_offset(), which doesn't reject valid offsets when the framebuffer area is at the very end of the card's 32 bit address space. Make radeon_check_and_fixup_offset() use radeon_check_offset() as well. This fixes https://bugs.freedesktop.org/show_bug.cgi?id=7697 .
2006-12-11i915_vblank_tasklet: Try harder to avoid tearing.=?utf-8?q?Michel_D=C3=A4nzer?=
Previously, if there were several buffer swaps scheduled for the same vertical blank, all but the first blit emitted stood a chance of exhibiting tearing. In order to avoid this, split the blits along slices of each output top to bottom. Signed-off-by: Dave Airlie <airlied@linux.ie>

Initialize it to default value if it hasn't been set by the X server yet. In i915_vblank_pipe_set(), only update dev_priv->vblank_pipe and call i915_enable_interrupt() if the argument passed from userspace is valid to avoid corrupting dev_priv->vblank_pipe on invalid arguments.

2006-12-07drm: DRM_I915_VBLANK_SWAP ioctl: Take drm_vblank_seq_type_t instead=?utf-8?q?Michel_D=C3=A4nzer?=
of pipe number. Handle relative as well as absolute target sequence numbers. Return error if target sequence has already passed, so userspace can deal with this situation as it sees fit. On success, return the sequence number of the vertical blank when the buffer swap is expected to take place. Also add DRM_IOCTL_I915_VBLANK_SWAP definition for userspace code that may want to use ioctl() instead of drmCommandWriteRead(). Signed-off-by: Dave Airlie <airlied@linux.ie>
2006-12-07drm: i915: Add ioctl for scheduling buffer swaps at vertical blanks.=?utf-8?q?Michel_D=C3=A4nzer?=

2006-12-07drm: Core vsync: Add flag DRM_VBLANK_NEXTONMISS.=?utf-8?q?Michel_D=C3=A4nzer?=

Actually make the existing ioctls for adding and removing drawables do something useful, and add another ioctl for the X server to update drawable information. The only kind of drawable information tracked so far is cliprects. Only reallocate cliprect memory if the number of cliprects changes. Also improve diagnostic output. hook up drm ioctl update draw export drm_get_drawable_info symbol Signed-off-by: Dave Airlie <airlied@linux.ie>

2006-10-24drm: radeon: only allow specific type-3 packetss through verifierRoland Scheidegger
only allow specific type-3 packets to pass the verifier instead of all for r100/r200 as others might be unsafe (r300 already does this), and add checking for these we need but aren't safe. Check the RADEON_CP_INDX_BUFFER packet on both r200 and r300 as it isn't safe neither. Signed-off-by: Dave Airlie <airlied@linux.ie>
2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.
