Xe, is a new driver for Intel GPUs that supports both integrated and discrete platforms starting with Tiger Lake (first Intel Xe Architecture). The code is at a stage where it is already functional and has experimental support for multiple platforms starting from Tiger Lake, with initial support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan drivers), as well as in NEO (for OpenCL and Level0). The new Xe driver leverages a lot from i915. As for display, the intent is to share the display code with the i915 driver so that there is maximum reuse there. But it is not added in this patch. This initial work is a collaboration of many people and unfortunately the big squashed patch won't fully honor the proper credits. But let's get some git quick stats so we can at least try to preserve some of the credits: Co-developed-by:

Xe needs intel_fb_bo_framebuffer_fini for taking care of unpinning the fb and taking reference. In i915 this can be empty. Also move intel_frontbuffer_get to be done after intel_fb_bo_framebuffer_init to have reasonable sequences: intel_fb_bo_framebuffer_init intel_frontbuffer_get ... intel_frontbuffer_put intel_fb_bo_framebuffer_fini v2: Empty function instead of define Signed-off-by:

The uncore code may not always be available (e.g. when we build the display code with Xe), so we can't always rely on having the uncore's spinlock. To handle this, split the spin_lock/unlock_irqsave/restore() into spin_lock/unlock() followed by a call to local_irq_save/restore() and create wrapper functions for locking and unlocking the uncore's spinlock. In these functions, we have a condition check and only actually try to lock/unlock the spinlock when I915 is defined, and thus uncore is available. This keeps the ifdefs contained in these new functions and all such logic inside the display code.

It's been reported that DSI host driver's detach can be called without the attach ever happening: https://lore.kernel.org/all/20230412073954.20601-1-tony@atomide.com/ After reading the code, I think this is what happens: We have a DSI host defined in the device tree and a DSI peripheral under that host (i.e. an i2c device using the DSI as data bus doesn't exhibit this behavior). The host driver calls mipi_dsi_host_register(), which causes (via a few functions) mipi_dsi_device_add() to be called for the DSI peripheral. So now we have a DSI device under the host, but attach hasn't been called. Normally the probing of the devices continues, and eventually the DSI peripheral's driver will call mipi_dsi_attach(), attaching the peripheral. However, if the host driver's probe encounters an error after calling mipi_dsi_host_register(), and before the peripheral has called mipi_dsi_attach(), the host driver will do cleanups and return an error from its probe function. The cleanups include calling mipi_dsi_host_unregister(). mipi_dsi_host_unregister() will call two functions for all its DSI peripheral devices: mipi_dsi_detach() and mipi_dsi_device_unregister(). The latter makes sense, as the device exists, but the former may be wrong as attach has not necessarily been done. To fix this, track the attached state of the peripheral, and only detach from mipi_dsi_host_unregister() if the peripheral was attached. Note that I have only tested this with a board with an i2c DSI peripheral, not with a "pure" DSI peripheral. However, slightly related, the unregister machinery still seems broken. E.g. if the DSI host driver is unbound, it'll detach and unregister the DSI peripherals. After that, when the DSI peripheral driver unbound it'll call detach either directly or using the devm variant, leading to a crash. And probably the driver will crash if it happens, for some reason, to try to send a message via the DSI bus. But that's another topic. Tested-by:

The i2c_master_send/recv() functions return negative error codes or they return "len" on success. So the error handling here can be written as just normal checks for "if (ret < 0) return ret;". No need to complicate things. Btw, in this code the "len" parameter can never be zero, but even if it were, then I feel like this would still be the best way to write it.

DRM drivers with user-space mode setting have been removed in Linux v6.3. [1] Now remove the ioctl entry points for these drivers. Invoking any of the ioctl ops will unconditionally return -EINVAL to user space. Invoking DRM_IOCTL_MODESET_CTL is different from the other legacy ioctl ops as it returns 0 even without CONFIG_DRM_LEGACY set. From the original commit 29935554 ("drm: Disallow DRM_IOCTL_MODESET_CTL for KMS drivers") it is not apparent how or why the operation differs from the others. It is likely just an oversight in commit 61ae2270 ("drm: allow removal of legacy codepaths (v4.1)"), which allowed disabling leagacy ioctls in the first place. Still keep this removal separate from the other ioctls to allow an easy revert, if necessary. Signed-off-by:
