The hw also has 3 rings for commands, cursor and release handling. - -The hardware also have a surface id tracking mechnaism and the driver encapsulates it completely inside the kernel, userspace never sees the actual hw surface -ids. - -This requires a newer version of the QXL userspace driver, so shouldn't be -enabled until that has been placed into your distro of choice. - -Authors: Dave Airlie, Alon Levy - -v1.1: fixup some issues in the ioctl interface with padding -v1.2: add module device table -v1.3: fix nomodeset, fbcon leak, dumb bo create, release ring irq, - don't try flush release ring (broken hw), fix -modesetting. - -Signed-off-by: Alon Levy <alevy@redhat.com> -Signed-off-by: Dave Airlie <airlied@redhat.com> ---- - drivers/gpu/drm/Kconfig | 2 + - drivers/gpu/drm/Makefile | 1 + - drivers/gpu/drm/qxl/Kconfig | 10 + - drivers/gpu/drm/qxl/Makefile | 9 + - drivers/gpu/drm/qxl/qxl_cmd.c | 707 +++++++++++++++++++++++++++ - drivers/gpu/drm/qxl/qxl_debugfs.c | 135 ++++++ - drivers/gpu/drm/qxl/qxl_dev.h | 879 ++++++++++++++++++++++++++++++++++ - drivers/gpu/drm/qxl/qxl_display.c | 981 ++++++++++++++++++++++++++++++++++++++ - drivers/gpu/drm/qxl/qxl_draw.c | 384 +++++++++++++++ - drivers/gpu/drm/qxl/qxl_drv.c | 145 ++++++ - drivers/gpu/drm/qxl/qxl_drv.h | 566 ++++++++++++++++++++++ - drivers/gpu/drm/qxl/qxl_dumb.c | 93 ++++ - drivers/gpu/drm/qxl/qxl_fb.c | 567 ++++++++++++++++++++++ - drivers/gpu/drm/qxl/qxl_fence.c | 97 ++++ - drivers/gpu/drm/qxl/qxl_gem.c | 178 +++++++ - drivers/gpu/drm/qxl/qxl_image.c | 120 +++++ - drivers/gpu/drm/qxl/qxl_ioctl.c | 411 ++++++++++++++++ - drivers/gpu/drm/qxl/qxl_irq.c | 97 ++++ - drivers/gpu/drm/qxl/qxl_kms.c | 302 ++++++++++++ - drivers/gpu/drm/qxl/qxl_object.c | 365 ++++++++++++++ - drivers/gpu/drm/qxl/qxl_object.h | 112 +++++ - drivers/gpu/drm/qxl/qxl_release.c | 307 ++++++++++++ - drivers/gpu/drm/qxl/qxl_ttm.c | 577 ++++++++++++++++++++++ - include/uapi/drm/Kbuild | 1 + - include/uapi/drm/qxl_drm.h | 152 ++++++ - 25 files changed, 7198 insertions(+) - create mode 100644 drivers/gpu/drm/qxl/Kconfig - create mode 100644 drivers/gpu/drm/qxl/Makefile - create mode 100644 drivers/gpu/drm/qxl/qxl_cmd.c - create mode 100644 drivers/gpu/drm/qxl/qxl_debugfs.c - create mode 100644 drivers/gpu/drm/qxl/qxl_dev.h - create mode 100644 drivers/gpu/drm/qxl/qxl_display.c - create mode 100644 drivers/gpu/drm/qxl/qxl_draw.c - create mode 100644 drivers/gpu/drm/qxl/qxl_drv.c - create mode 100644 drivers/gpu/drm/qxl/qxl_drv.h - create mode 100644 drivers/gpu/drm/qxl/qxl_dumb.c - create mode 100644 drivers/gpu/drm/qxl/qxl_fb.c - create mode 100644 drivers/gpu/drm/qxl/qxl_fence.c - create mode 100644 drivers/gpu/drm/qxl/qxl_gem.c - create mode 100644 drivers/gpu/drm/qxl/qxl_image.c - create mode 100644 drivers/gpu/drm/qxl/qxl_ioctl.c - create mode 100644 drivers/gpu/drm/qxl/qxl_irq.c - create mode 100644 drivers/gpu/drm/qxl/qxl_kms.c - create mode 100644 drivers/gpu/drm/qxl/qxl_object.c - create mode 100644 drivers/gpu/drm/qxl/qxl_object.h - create mode 100644 drivers/gpu/drm/qxl/qxl_release.c - create mode 100644 drivers/gpu/drm/qxl/qxl_ttm.c - create mode 100644 include/uapi/drm/qxl_drm.h - -diff --git a/drivers/gpu/drm/Kconfig b/drivers/gpu/drm/Kconfig -index 1e82882..19b8e0d 100644 ---- a/drivers/gpu/drm/Kconfig -+++ b/drivers/gpu/drm/Kconfig -@@ -220,3 +220,5 @@ source "drivers/gpu/drm/tegra/Kconfig" - source "drivers/gpu/drm/omapdrm/Kconfig" - - source "drivers/gpu/drm/tilcdc/Kconfig" -+ -+source "drivers/gpu/drm/qxl/Kconfig" -diff --git a/drivers/gpu/drm/Makefile b/drivers/gpu/drm/Makefile -index 0d59b24..6a42115 100644 ---- a/drivers/gpu/drm/Makefile -+++ b/drivers/gpu/drm/Makefile -@@ -52,4 +52,5 @@ obj-$(CONFIG_DRM_SHMOBILE) +=shmobile/ - obj-$(CONFIG_DRM_TEGRA) += tegra/ - obj-$(CONFIG_DRM_OMAP) += omapdrm/ - obj-$(CONFIG_DRM_TILCDC) += tilcdc/ -+obj-$(CONFIG_DRM_QXL) += qxl/ - obj-y += i2c/ -diff --git a/drivers/gpu/drm/qxl/Kconfig b/drivers/gpu/drm/qxl/Kconfig -new file mode 100644 -index 0000000..2f1a57e ---- /dev/null -+++ b/drivers/gpu/drm/qxl/Kconfig -@@ -0,0 +1,10 @@ -+config DRM_QXL -+ tristate "QXL virtual GPU" -+ depends on DRM && PCI -+ select FB_SYS_FILLRECT -+ select FB_SYS_COPYAREA -+ select FB_SYS_IMAGEBLIT -+ select DRM_KMS_HELPER -+ select DRM_TTM -+ help -+ QXL virtual GPU for Spice virtualization desktop integration.
