| | | | | | | | | 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>

* drm/i915: Change I2C api to pass around i2c_adaptersKeith Packard2009-06-18
| | | | | | | | | | | | 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. Signed-off-by: Keith Packard <keithp@keithp.com>

* drm/i915: Clear fence register on tiling stride change.Chris Wilson2009-06-18

* drm/i915: Install fence register for tiled scanout on i915Chris Wilson2009-06-18
| | | | | | | | | | | | 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.

In order to avoid backward compatibility issue and to allow clean design and code the radeon kernel modesetting use different code path than old radeon/drm driver. When kernel modesetting is enabled the IOCTL of radeon/drm driver are considered as invalid and an error message is printed in the log and they return failure. KMS enabled userspace will use new API to talk with the radeon/drm driver. The new API provide functions to create/destroy/share/mmap buffer object which are then managed by the kernel memory manager (here TTM). In order to submit command to the GPU the userspace provide a buffer holding the command stream, along this buffer userspace have to provide a list of buffer object used by the command stream. The kernel radeon driver will then place buffer in GPU accessible memory and will update command stream to reflect the position of the different buffers. The kernel will also perform security check on command stream provided by the user, we want to catch and forbid any illegal use of the GPU such as DMA into random system memory or into memory not owned by the process supplying the command stream. This part of the code is still incomplete and this why we propose that patch as a staging driver addition, future security might forbid current experimental userspace to run. This code support the following hardware : R1XX,R2XX,R3XX,R4XX,R5XX (radeon up to X1950). Works is underway to provide support for R6XX, R7XX and newer hardware (radeon from HD2XXX to HD4XXX).

| * drm: Add the TTM GPU memory manager subsystem.Thomas Hellstrom2009-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TTM is a GPU memory manager subsystem designed for use with GPU devices with various memory types (On-card VRAM, AGP, PCI apertures etc.). It's essentially a helper library that assists the DRM driver in creating and managing persistent buffer objects. TTM manages placement of data and CPU map setup and teardown on data movement. It can also optionally manage synchronization of data on a per-buffer-object level. TTM takes care to provide an always valid virtual user-space address to a buffer object which makes user-space sub-allocation of big buffer objects feasible. TTM uses a fine-grained per buffer-object locking scheme, taking care to release all relevant locks when waiting for the GPU. Although this implies some locking overhead, it's probably a big win for devices with multiple command submission mechanisms, since the lock contention will be minimal. TTM can be used with whatever user-space interface the driver chooses, including GEM. It's used by the upcoming Radeon KMS DRM driver and is also the GPU memory management core of various new experimental DRM drivers.

It uses new aperture_base/size members instead of comparing on the fix smem_start/length, as smem_start/length might for example only cover the first 1MB of the PCI aperture, and we could allocate the kms fb from 8MB into the aperture, thus they would never overlap.

Sometimes it is inconvenient to get the debug info in KMS mode. We will get too much unrelated info. This will separate several DRM debug levels and the debug level can be used to print the different debug info. And the debug level is controlled by the module parameter of drm.debug In this patch it is divided into four debug levels; drm_core, drm_driver, drm_kms, drm_mode. At the same time we can get the different debug info by changing the debug level. This can be done by adding the module parameter. Of course it can be changed through the /sys/module/drm/parameters/debug after the system is booted. Four debug macro definitions are provided. DRM_DEBUG(fmt, args...) DRM_DEBUG_DRIVER(prefix, fmt, args...) DRM_DEBUG_KMS(prefix, fmt, args...) DRM_DEBUG_MODE(prefix, fmt, args...) When the boot option of "drm.debug=4" is added, it will print the debug info using DRM_DEBUG_KMS macro definition. When the boot option of "drm.debug=6" is added, it will print the debug info using DRM_DEBUG_KMS/DRM_DEBUG_DRIVER. Sometimes we expect to print the value of an array. For example: SDVO command, In such case the following four DRM debug macro definitions are added: DRM_LOG(fmt, args...) DRM_LOG_DRIVER(fmt, args...) DRM_LOG_KMS(fmt, args...)
