Paul Cercueil authored
Add a KMS driver for the Ingenic JZ47xx family of SoCs. This driver is meant to replace the aging jz4740-fb driver. This driver does not make use of the simple pipe helper, for the reason that it will soon be updated to support more advanced features like multiple planes, IPU integration for colorspace conversion and up/down scaling, support for DSI displays, and TV-out and HDMI outputs. Notes: v2: - Remove custom handling of panel. The panel is now discovered using the standard API. - Lots of small tweaks suggested by upstream v3: - Use devm_drm_dev_init() - Update compatible strings to -lcd instead of -drm - Add destroy() callbacks to plane and crtc - The ingenic,lcd-mode is now read from the bridge's DT node v4: Remove ingenic,lcd-mode property completely. The various modes are now deduced from the connector type, the pixel format or the bus flags. v5: - Fix framebuffer size incorrectly calculated for 24bpp framebuffers - Use 32bpp framebuffer instead of 16bpp, as it'll work with both 16-bit and 24-bit panel - Get rid of drm_format_plane_cpp() which has been dropped upstream - Avoid using drm_format_info->depth, which is deprecated.

Rotations and reflections setup are needed in some scenarios to initialise properly the initial framebuffer. Some drivers already had a bunch of quirks to deal with this, such as either a private kernel command line parameter (omapdss) or on the device tree (various panels). In order to accomodate this, let's create a video mode parameter to deal with the rotation and reflexion.

The drm subsystem also uses the video= kernel parameter, and in the documentation refers to the fbdev documentation for that parameter. However, that documentation also says that instead of giving the mode using its resolution we can also give a name. However, DRM doesn't handle that case at the moment. Even though in most case it shouldn't make any difference, it might be useful for analog modes, where different standards might have the same resolution, but still have a few different parameters that are not encoded in the modes (NTSC vs NTSC-J vs PAL-M for example).

The drm_client_rotation has a check on the rotation value, but the reflections are also stored in the same variable, and the check doesn't take this into account. Therefore, even though we might have a valid rotation, if we're also using a reflection parameter, the test will fail for no particular reason.

The drm_client_modeset_commit_atomic function uses two times the plane_state variable in inner blocks of code, but the variable has a scope global to this function. This will lead to inadvertent devs to reuse the variable in the second block with the value left by the first, without any warning from the compiler since value would have been initialized. Fix this by moving the variable declaration to the proper scope.

Since commit 4b050ba7 ("MIPS: pgtable.h: Implement the pgprot_writecombine function for MIPS") and commit c4687b15 ("MIPS: Fix definition of pgprot_writecombine()") write-combine vma mapping is available to be used by kernel subsystems for MIPS. In particular the uncached accelerated attribute is requested to be set by ioremap_wc() method and by generic PCI memory pages/ranges mapping methods. The same is done by the drm_io_prot()/ttm_io_prot() functions in case if write-combine flag is set for vma's passed for mapping. But for some reason the pgprot_writecombine() method calling is ifdefed to be a platform-specific with MIPS system being marked as lacking of one. At the very least it doesn't reflect the current MIPS platform implementation. So in order to improve the DRM subsystem performance on MIPS with UCA mapping enabled, we need to have pgprot_writecombine() called for buffers, which need store operations being combined. In case if particular MIPS chip doesn't support the UCA attribute, the mapping will fall back to noncached.

Expose performance counters through 2 driver specific ioctls: one to enable/disable the perfcnt block, and one to dump the counter values. There are discussions to expose global performance monitors (those counters that can't be retrieved on a per-job basis) in a consistent way, but this is likely to take time to settle on something that works for various HW/users. The ioctls are marked unstable so we can get rid of them when the time comes. We initally went for a debugfs-based interface, but this was making the transition to per-FD address space more complicated (we need to specify the namespace the GPU has to use when dumping the perf counters), hence the decision to switch back to driver specific ioctls which are passed the FD they operate on and thus will have a dedicated address space attached to them. Other than that, the implementation is pretty simple: it basically dumps all counters and copy the values to a userspace buffer. The parsing is left to userspace which has to know the specific layout that's used by the GPU (layout differs on a per-revision basis).

We plan to expose performance counters through 2 driver specific ioctls until there's a solution to expose them in a generic way. In order to be able to deprecate those ioctls when this new infrastructure is in place we add an unsafe module parameter that will keep those ioctls hidden unless it's set to true (which also has the effect of tainting the kernel). All unstable ioctl handlers should use panfrost_unstable_ioctl_check() to check whether they're supposed to handle the request or reject it with ENOSYS.

At one point, the GPU command verifier and user-space handle manager couldn't properly protect GPU clients from accessing each other's data. Instead there was an elaborate mechanism to make sure only the active master's primary clients could render. The other clients were either put to sleep or even killed (if the master had exited). VRAM was evicted on master switch. With the advent of render-node functionality, we relaxed the VRAM eviction, but the other mechanisms stayed in place. Now that the GPU command verifier and ttm object manager properly isolate primary clients from different master realms we can remove the master switch related code and drop those legacy features.

With emulated coherent memory we need to be able to quickly look up a resource from the MOB offset. Instead of traversing a linked list with O(n) worst case, use an RBtree with O(log n) worst case complexity.

This infrastructure will, for coherent resources, make sure that from the user-space point of view, data written by the CPU is immediately automatically available to the GPU at resource validation time.

With the vmwgfx dirty tracking, the default TTM fault handler is not completely sufficient (vmwgfx need to modify the vma->vm_flags member, and also needs to restrict the number of prefaults). We also want to replicate the new ttm_bo_vm_reserve() functionality So start turning the TTM vm code into helpers: ttm_bo_vm_fault_reserved() and ttm_bo_vm_reserve(), and provide a default TTM fault handler for other drivers to use.
