fbdev: Use _IOMEM_ infix for I/O-memory helpers

2023-07-31T18:06:52+00:00

Change the infix for fbdev's I/O-memory helpers from _IO_ to _IOMEM_ to distiguish them from other types of I/O, such as file operations. The helpers operate on memory ranges in the I/O address space and the naming should make this clear. Adapt all users. No functional changes.

drm/i915: Implement dedicated fbdev I/O helpers

2023-06-01T10:41:40+00:00

Implement dedicated fbdev helpers for framebuffer I/O instead of using DRM's helpers. Use an fbdev generator macro for deferred I/O to create the fbdev callbacks. i915 was the only caller of the DRM helpers, so remove them from the helper module. i915's fbdev emulation is still incomplete as it doesn't implement deferred I/O and damage handling for mmaped pages. v4: * generate deferred-I/O helpers * use initializer macros for fb_ops v2: * use FB_IO_HELPERS options Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Cc: Jani Nikula Cc: Joonas Lahtinen Cc: Rodrigo Vivi Cc: Tvrtko Ursulin Cc: "Ville Syrjälä" Link: https://patchwork.freedesktop.org/patch/msgid/20230530151228.22979-14-tzimmermann@suse.de

drm/i915: taint kernel when force probing unsupported devices

2023-05-11T11:11:59+00:00

For development and testing purposes, the i915.force_probe module parameter and DRM_I915_FORCE_PROBE kconfig option allow probing of devices that aren't supported by the driver. The i915.force_probe module parameter is "unsafe" and setting it taints the kernel. However, using the kconfig option does not. Always taint the kernel when force probing a device that is not supported. v2: Drop "depends on EXPERT" to avoid build breakage (kernel test robot) Fixes: 7ef5ef5cdead ("drm/i915: add force_probe module parameter to replace alpha_support") Cc: Joonas Lahtinen Cc: Rodrigo Vivi Cc: Tvrtko Ursulin Cc: Daniel Vetter Cc: Dave Airlie Acked-by: Daniel Vetter Reviewed-by: Rodrigo Vivi Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20230504103508.1818540-1-jani.nikula@intel.com (cherry picked from commit 3312bb4ad09ca6423bd4a5b15a94588a8962fb8e) Signed-off-by: Joonas Lahtinen

drm/i915: remove unused config DRM_I915_UNSTABLE

2023-03-28T15:10:11+00:00

Essentially this is a revert of commit d9d54a530a70 ("drm/i915: Put future HW and their uAPIs under STAGING & BROKEN"). We currently have no users for this config option. The last one was removed in commit 8c26491f5853 ("drm/i915: Kill the fake lmem support"). Drop it altogether; it's easy enough to resurrect if need arises.
