Simplify ast_astdp_read_edid(). Rename register constants. Drop unnecessary error handling. On success, the helper returns 0; an error code otherwise. Signed-off-by:

The place for link training is in the encoder's atomic_enable helper. Remove all related tests from other helper ASTDP functions; especially ast_astdp_is_connected(), which tests HPD status. DP link training is controlled by the firmware. A status flag reports success or failure. The process can be fragile on Aspeed hardware. Moving the test from connector detection to the atomic_enable allows for several retries and a longer timeout. Signed-off-by:

The overall control flow of the driver ensures that it never reads EDID or sets display state on unconnected outputs. Therefore remove all tests for Hot Plug Detection from these helpers. Also rename the register constants. Signed-off-by:

Test for running ASTDP firmware during probe. Do not bother testing this later. We cannot do much anyway if the firmware fails. Do not initialize the ASTDP conenctor if the test fails during device probing. Signed-off-by:

I2C v7, SMBus 3.2, and I3C 1.1.1 specifications have replaced "master/slave" with more appropriate terms. Inspired by Wolfram's series to fix drivers/i2c/, fix the terminology for users of I2C_ALGOBIT bitbanging interface, now that the approved verbiage exists in the specification. Acked-by:

Ben Skeggs authored
The only remaining nouveau_drm.master struct member that's being used is the mutex that protects its object tree. Move that into nouveau_drm and remove nouveau_drm.master entirely. A pending series to remove the "ioctl" layer between DRM and NVKM also removes the need for object handle lookups, and hence this mutex, but it's still required for the moment. Signed-off-by:

The nouveau_cli that owns the channel is now stored in nouveau_chan, and it has a pointer to the drm device already. Signed-off-by:

nouveau_chan.device is always the same as nouveau_chan.cli.device, so there's no need to store it separately. Signed-off-by:

Both of these are stored in nouveau_cli already, and also allows the removal of some void casts. Signed-off-by:

The nouveau_cli pointer is only ever used to eventually access nouveau_drm, so just store it directly. Signed-off-by:

This allocates a new nvif_mmu in nouveau_drm, and uses it for TTM backend memory allocations instead of nouveau_drm.master.mmu, which is removed by a later commit that removes nouveau_drm.master entirely. Signed-off-by:

Ben Skeggs authored
These are some dodgy "convenience" macros for the DRM driver to peek into NVKM state. They're still used in a few places, but don't belong in nvif/device.h in any case. Move them to nouveau_drv.h, and modify callers to pass a nouveau_drm instead of an nvif_device. v2: - use drm->nvkm pointer for nvxx_*() macros, removing some void* v3: - add some explanation of the nvxx_*() macros Signed-off-by:

There's no good reason the ioremap() that results from nvif_object_map() should fail, so add a check that the map succeeded, and remove the rd/wr methods from display channel objects. As this was the last user of rd/wr methods, the nvif plumbing is removed at the same time. Signed-off-by:

The previous commit ensures the device is always mapped, so these are unneeded. Signed-off-by:

Ben Skeggs authored
The next commit removes the nvif rd/wr methods from nvif_device, which were probably a bad idea, and mostly intended as a fallback if ioremap() failed (or wasn't available, as was the case in some tools I once used). The nv04 KMS driver already mapped the device, because it's mostly been kept alive on life-support for many years and still directly bashes PRI a lot for modesetting. Post-nv50, I tried pretty hard to keep PRI accesses out of the DRM code, but there's still a few random places where we do, and those were using the rd/wr paths prior to this commit. This allocates and maps a new nvif_device (which will replace the usage of nouveau_drm.master.device later on), and replicates this pointer to all other possible users. This will be cleaned up by the end of another patch series, after it's been made safe to do so. Signed-off-by:

These were once used by used by userspace tools (with nvkm built as a library), to access multiple GPUs from a single nvif_client. The DRM code just uses the driver's default device, so remove the arguments. Signed-off-by:

This was once used by userspace tools (with nvkm built as a library), as a way to select a "default device". The DRM code doesn't need this at all as clients only have access to a single device already, so inherit the value from its parent. Signed-off-by:

This hasn't been used in a while. Moves io accessors from nvkm/core/os.h to nvif/os.h at the same time to fix a compile issue that results from <nvkm/core/object.h> no longer being included. Signed-off-by:

These were a cludge used to prevent userspace's nvif ioctl from accessing objects created by the kernel for the same client. That interface was removed in a previous patch, so these are no longer useful for anything. Signed-off-by:

This has never really been used for anything, in part due to never having reclocking stable enough in general to attempt to implement dynamic clock changes based on load, etc. To avoid having to rework its interfaces, remove it entirely. Signed-off-by:

The previous commit removes the last remnants of userspace's own nvif instance, so this isn't needed anymore to hide the abi16 objects from userspace and we can use nouveau_cli.device instead. Signed-off-by:
-
Ben Skeggs authored
nouveau_usif.c was already stripped right back a couple of years ago, limiting what userspace could do with it. A follow-on series removes the nvkm side of these interfaces entirely, in order to make it less of a nightmare to add/change internal APIs in the future. Unfortunately. Userspace uses some of this. Fortunately, userspace only ever ended up using a fraction of the APIs, so those are reimplemened here in a more direct manner, and return -EINVAL to userspace for everything else. v2: - simplified struct nouveau_abi16_obj - added a couple of comments v3: - comment harder Signed-off-by:
