TTM need to be initialized before radeon if KMS is enabled otherwise the kernel will crash hard. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@linux.ie>
2009-06-24drm: Fix shifts which were miscalculated when converting from bitfields.Michel Dänzer1-6/+6
Looks like I managed to mess up most shifts when converting from bitfields. :( The patch below works on my Thinkpad T500 (as well as on my PowerBook, where the previous change worked as well, maybe out of luck...). I'd appreciate more testing and eyes looking over it though. Signed-off-by: Michel Dänzer <daenzer@vmware.com> Tested-by: Michael Pyne <mpyne@kde.org> Signed-off-by: Dave Airlie <airlied@linux.ie>

2009-06-24ACPI: Add the reference count to avoid unloading ACPI video bus twiceZhao Yakui1-1/+1
Sometimes both acpi video and i915 driver are compiled as modules. And there exists the strict dependency between the two drivers. The acpi video bus will be unloaded in course of unloading the i915 driver. If we unload the acpi video driver, then the kernel oops will be triggered. Add the reference count to avoid unloading the ACPI video bus twice. The reference count should be checked before unregistering the acpi video bus. If the reference count is already zero, it won't unregister it again. And after the acpi video bus is already unregistered, the reference count will be set to zero. http://bugzilla.kernel.org/show_bug.cgi?id=13396 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Acked-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-06-23drm/i915: initialize fence registers to zero when loading GEMGrégoire Henry1-0/+13

2009-06-23drm/i915: fix LFP data fetchJesse Barnes1-1/+11
Apparently the proper way to do this is to use the LFP data pointer block to figure out the LFP data block entry size, then use that plus the panel index to calculate an offset into the LFP data block array. Similar fix has already been pushed to the 2D driver to fix fdo bug applied to the VBIOS reader, and things look sane).

2009-06-23drm/i915: set TV detection mode when tv is already connectedling.ma@intel.com1-28/+25
We used load_detect_temp flag to determine whether to set tv to the test mode. However if the TV already has a mode set, we still need to set the test mode to determine connection. This results in blinking, but there is no other reliable way to determine TV connection. freedesktop.org bug #22035 Signed-off-by: Ma Ling <ling.ma@intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>

2009-06-23drm/i915: Don't change the blank/sync width when calculating scaled modesZhao Yakui1-18/+73
Also, use the border instead of border minus one. At the same time, make sure the horizontal border and hsync are even for the LVDS that works in dual-channel mode. So both horizontal border and hsync start are also changed to be even, even for the LVDS in single-channel mode. https://bugs.freedesktop.org/show_bug.cgi?id=20951 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>
2009-06-23drm/i915: Add support for changing LVDS panel fitting using an output property.Zhao Yakui2-21/+280
Previously the driver would always scale the chosen video mode to fill the panel. This adds 1:1 and maintain-aspect-ratio scaling modes. v2: the drm_calloc/drm_free is replaced by kzalloc/kfree based on Eric's suggestion.

2009-06-23drm/i915: correct suspend/resume orderingJesse Barnes1-2/+2
We need to save register state *after* idling GEM, clearing the ring, and uninstalling the IRQ handler, or we might end up saving bogus fence regs, for one. Our restore ordering should already be correct, since we do GEM, ring and IRQ init after restoring the last register state, which prevents us from clobbering things. I put this together to potentially address a bug, but I haven't heard back if it fixes it yet. However I think it stands on its own, so I'm sending it in.

2009-06-22drm/i915: Add missing dependency on Intel AGP support.Eric Anholt1-0/+1

2009-06-19drm/i915: enable GEM on PAE.Dave Airlie1-5/+0

2009-06-19agp: switch AGP to use page array instead of unsigned long arrayDave Airlie4-9/+8
This switches AGP to use an array of pages for tracking the pages allocated to the GART. This should enable GEM on PAE to work a lot better as we can pass highmem pages to the PAT code and it will do the right thing with them. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-06-19drm/radeon: command stream checker for r3xx-r5xx hardwareJerome Glisse7-65/+611
For security purpose we want to make sure the userspace process doesn't access memory beyond buffer it owns. To achieve this we need to check states the userspace program. For color buffer and zbuffer we check that the clipping register will discard access beyond buffers set as color or zbuffer. For vertex buffer we check that no vertex fetch will happen beyond buffer end. For texture we check various texture states (number of mipmap level, texture size, texture depth, ...) to compute the amount of memory the texture fetcher might access. The command stream checking impact the performances so far quick benchmark shows an average of 3% decrease in fps of various applications. It can be optimized a bit more by caching result of checking and thus avoid a full recheck if no states changed since last check. Note that this patch is still incomplete on checking side as it doesn't check 2d rendering states. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-06-19drm/i915: Generate 2MHz clock for display port aux channel I/O. Retry I/O.Keith Packard1-32/+70
The display port aux channel clock is taken from the hrawclk value, which is provided to the chip as the FSB frequency (as far as I can determine). The strapping values for that are available in the CLKCFG register, now used to select an appropriate divider to generate a 2MHz clock. In addition, the DisplayPort spec requires that each aux channel I/O be retried 'at least 3 times' in case the sink is idle when the first request comes in.

2009-06-19drm/i915: Split array of DAC limits into separate structures.Keith Packard1-57/+51
The array of DAC limits was only ever referenced with #defined constant offsets, and keeping those #define values in sync with the array itself was a nuisance. This will make future changes to the set of DAC limits less error-prone. Signed-off-by: Keith Packard <keithp@keithp.com>

2009-06-19drm/i915: Change I2C api to pass around i2c_adaptersKeith Packard12-113/+118
The existing API passed around intel_i2c_chan pointers, which are dependent on the i2c bit-banging algo. This precluded the driver from using outputs which use a different algo. Switching to the more general i2c_adpater allows the driver to support non bit-banging DDC. This also required moving the slave address into the output private structures.

2009-06-18drm/i915: Clear fence register on tiling stride change.Chris Wilson3-17/+88

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> [anholt: Added 8xx and 965 paths, and renamed the confusing i915_gem_object_tiling_ok function to i915_gem_object_fence_offset_ok] Signed-off-by: Eric Anholt <eric@anholt.net>
2009-06-18drm/i915: Install fence register for tiled scanout on i915Chris Wilson3-10/+21
With the work by Jesse Barnes to eliminate allocation of fences during execbuffer, it becomes possible to write to the scan-out buffer with it never acquiring a fence (simply by only ever writing to the object using tiled GPU commands and never writing to it via the GTT). So for pre-i965 chipsets which require fenced access for tiled scan-out buffers, we need to obtain a fence register.
