Upgrade it to ~512K (which definitely is more than enough). To allow testing userspace support for >64 devices, add additional DRM modparam (force_extended_minors) which causes DRM to skip allocating minors in 0-192 range. Additionally - convert minors to use XArray instead of IDR to simplify the locking. v1 -> v2: Don't touch DRM_MINOR_CONTROL and its range (Simon Ser) v2 -> v3: Don't use legacy scheme for >=192 minor range (Dave Airlie) Add modparam for testing (Dave Airlie) Add lockdep annotation for IDR (Daniel Vetter) v3 -> v4: Convert from IDR to XArray (Matthew Wilcox) v4 -> v5: Fixup IDR to XArray conversion (Matthew Wilcox) v5 -> v6: Also convert Accel to XArray Rename skip_legacy_minors to force_extended_minors Michał Winiarski (4): drm: Use XArray instead of IDR for minors accel: Use XArray instead of IDR for minors drm: Expand max DRM device number to full MINORBITS drm: Introduce force_extended_minors modparam drivers/accel/drm_accel.c | 110 +++------------------------------ drivers/gpu/drm/drm_drv.c | 105 ++++++++++++++++--------------- drivers/gpu/drm/drm_file.c | 2 +- drivers/gpu/drm/drm_internal.h | 4 -- include/drm/drm_accel.h | 18 +----- include/drm/drm_file.h | 5 ++ 6 files changed, 69 insertions(+), 175 deletions(-) </pre> </blockquote> </body> </html>
