drm/vgaarb: add VGA arbitration support to the drm and kms.

2009-09-21T05:00:27+00:00

VGA arb requires DRM support for non-kms drivers, to turn on/off irqs when disabling the mem/io regions. VGA arb requires KMS support for GPUs where we can turn off VGA decoding. Currently we know how to do this for intel and radeon kms drivers, which allows them to be removed from the arbiter. This patch comes from Fedora rawhide kernel. Signed-off-by: Dave Airlie

drm: GEM handles are u32, not int

2009-08-27T01:21:08+00:00

Several functions in the GEM kernel API used int as handle type, but user API has it __u32 which is also the intended type. Replace int with u32. Signed-off-by: Pekka Paalanen Signed-off-by: Dave Airlie

DRM: Add the explanation about DRM debug level

2009-08-04T04:02:41+00:00

Add the explanation about DRM debug level in the drmP header file. This is to explain how/where to use the different DRM debug level. Signed-off-by: Zhao Yakui Signed-off-by: Dave Airlie

drm: Remove the macro defintion of DRM_DEBUG_MODE

2009-08-04T04:02:39+00:00

Two macro definitions of DRM_DEBUG_KMS/MODE can be used to add the debug info related with KMS. It is confusing. So remove the macro definition of DRM_DEBUG_MODE. Instead it can be replaced by the DRM_DEBUG_KMS. Signed-off-by: Zhao Yakui Acked-by: Ian Romanick Signed-off-by: Dave Airlie

drm: Remove the unused prefix in DRM_DEBUG_KMS/DRIVER/MODE

2009-08-04T04:02:31+00:00

We will have to add a prefix when using the macro defintion of DRM_DEBUG_KMS /DRM_DEBUG_DRIVER/MODE. It is not convenient. We should use the DRM_NAME as default prefix. So remove the prefix in the macro definition of DRM_DEBUG_KMS/DRIVER/MODE. Signed-off-by: Zhao Yakui Acked-by: Ian Romanick Signed-off-by: Dave Airlie

drm: Remove memory debugging infrastructure.

2009-06-18T20:00:33+00:00

It hasn't been used in ages, and having the user tell your how much memory is being freed at free time is a recipe for disaster even if it was ever used. Signed-off-by: Eric Anholt

drm: Split out the mm declarations in a separate header. Add atomic operations.

2009-06-12T05:56:31+00:00

this is a TTM preparation patch, it rearranges the mm and add operations needed to do mm operations in atomic context. Signed-off-by: Thomas Hellstrom Signed-off-by: Dave Airlie

drm_calloc_large: check right size, check integer overflow, use GFP_ZERO

2009-06-12T05:37:28+00:00

Previously we would check size instead of size * nmemb, and so would never hit the vmalloc path. Also add integer overflow check as in kcalloc, and allocate GFP_ZERO pages instead of memset()ing them. Signed-off-by: Kristian Høgsberg Signed-off-by: Dave Airlie

drm: add separate drm debugging levels

2009-06-11T08:36:36+00:00

Now all the DRM debug info will be reported if the boot option of "drm.debug=1" is added. 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...) DRM_LOG_MODE(fmt, args...) Signed-off-by: Zhao Yakui Signed-off-by: Dave Airlie

drm: fix LOCK_TEST_WITH_RETURN macro

When this macro isn't called with 'file_priv' this will result in a build failure. Signed-off-by: Roel Kluin Signed-off-by: Andrew Morton Signed-off-by: Dave Airlie
