fe2b84f922 drm/amdgpu/gfx6: Support harvested SI chips with disabled TCCs (v2)
This commit fixes amdgpu to work on the Radeon HD 7870 XT
which has never worked with the Linux open source drivers before.

Some boards have "harvested" chips, meaning that some parts of
the chip are disabled and fused, and it's sold for cheaper and
under a different marketing name.
On a harvested chip, any of the following can be disabled:
- CUs (Compute Units)
- RBs (Render Backend, aka. ROP)
- Memory channels (ie. the chip has a lower bandwidth)
- TCCs (ie. less L2 cache)

Handle chips with harvested TCCs by patching the registers
that configure how TCCs are mapped.

If some TCCs are disabled, we need to make sure that
the disabled TCCs are not used, and the remaining TCCs
are used optimally.

TCP_CHAN_STEER_LO/HI control which TCC is used by TCP channels.
TCP_ADDR_CONFIG.NUM_TCC_BANKS controls how many channels are used.

Note that the TCC configuration is highly relevant to performance.
Suboptimal configuration (eg. CHAN_STEER=0) can significantly
reduce gaming performance.

For optimal performance:
- Rely on the CHAN_STEER from the golden registers table,
  only skip disabled TCCs but keep the mapping order.
- Limit NUM_TCC_BANKS to number of active TCCs to avoid thrashing,
  which performs better than using the same TCC twice.

v2:
- Also consider CGTS_USER_TCC_DISABLE for disabled TCCs.

13e4cf116d drm/amdgpu/uvd3.1: Don't validate the firmware when already validated
UVD 3.1 firmware validation seems to always fail after
attempting it when it had already been validated.
(This works similarly with the VCE 1.0 as well.)

Don't attempt repeating the validation when it's already done.

This caused issues in situations when the system isn't able
to suspend the GPU properly and so the GPU isn't actually
powered down. Then amdgpu would fail when calling the IP
block resume function.

0ef196a208 drm/amdgpu: fix AMDGPU_INFO_READ_MMR_REG
There were multiple issues in that code.

First of all the order between the reset semaphore and the mm_lock was
wrong (e.g. copy_to_user) was called while holding the lock.

Then we allocated memory while holding the reset semaphore which is also
a pretty big bug and can deadlock.

Then we used down_read_trylock() instead of waiting for the reset to
finish.

36d65da757 drm/amdgpu/gmc: Fix AMDGPU_GART_PLACEMENT_LOW to not overlap with VRAM
When the GART placement is set to AMDGPU_GART_PLACEMENT_LOW:
Make sure that GART does not overlap with VRAM when
VRAM is configured to be in the low address space.

Solve this according to the following logic:
- When GART fits before VRAM, use zero address for GART
- Otherwise, put GART after the end of VRAM, aligned to 4 GiB

Previously, I had assumed this was not possible
so it was OK to not handle it, but now we got a report
from a user who has a board that is configured this way.

508babf310 drm/amdgpu: avoid double drm_exec_fini() in userq validate
When new_addition is true, amdgpu_userq_vm_validate() calls
drm_exec_fini(&exec) before iterating over the collected HMM ranges and
calling amdgpu_ttm_tt_get_user_pages().

If amdgpu_ttm_tt_get_user_pages() fails in that path, the code jumps to
unlock_all and calls drm_exec_fini(&exec) a second time on the same
exec object. drm_exec_fini() is not idempotent: it frees exec->objects
and may also drop exec->contended and finalize the ww acquire context.

Route that error path directly to the range cleanup once exec has
already been finalized.

Fixes: 42f1487884 ("drm/amdgpu/userqueue: validate userptrs for userqueues")

095a8b0ad3 drm/amdgpu: fix zero-size GDS range init on RDNA4
RDNA4 (GFX 12) hardware removes the GDS, GWS, and OA on-chip memory
resources. The gfx_v12_0 initialisation code correctly leaves
adev->gds.gds_size, adev->gds.gws_size, and adev->gds.oa_size at
zero to reflect this.

amdgpu_ttm_init() unconditionally calls amdgpu_ttm_init_on_chip() for
each of these resources regardless of size. When the size is zero,
amdgpu_ttm_init_on_chip() forwards the call to ttm_range_man_init(),
which calls drm_mm_init(mm, 0, 0). drm_mm_init() immediately fires
DRM_MM_BUG_ON(start + size <= start) -- trivially true when size is
zero -- crashing the kernel during modprobe of amdgpu on an RX 9070 XT.

Guard against this by returning 0 early from
amdgpu_ttm_init_on_chip() when size_in_page is zero. This skips TTM
resource manager registration for hardware resources that are absent,
without affecting any other GPU type.

DRM_MM_BUG_ON() only asserts if CONFIG_DRM_DEBUG_MM is enabled in
the kernel config.  This is apparently rarely enabled as these chips
have been in the market for over a year and this issue was only reported
now.

778bf584f2 drm/amdgpu: OR init_pte_flags into invalid leaf PTE updates
Invalid leaf clears that only set AMDGPU_PTE_EXECUTABLE match the old
GMC9 fault-priority workaround but omit adev->gmc.init_pte_flags.
On GFX12 that includes AMDGPU_PTE_IS_PTE; without it, some cleared
PTEs can fault as no-retry and bypass the SVM/XNACK handler when a
VA is reused after a BO unmap.

Apply init_pte_flags in amdgpu_vm_pte_update_flags() alongside
EXECUTABLE so range-driven clears (e.g. amdgpu_vm_clear_freed) match
amdgpu_vm_pt_clear() for leaf templates.

dd88d42d9c drm/amdgpu: drop userq fence driver refs out of fence process()
amdgpu_userq_wait_ioctl() takes extra references on waited-on fence
drivers and stores them in waitq->fence_drv_xa. When a new userq fence is
created, those references are transferred into userq_fence->fence_drv_array
so they can be released when the fence completes.

However, those inherited references are currently only dropped from
amdgpu_userq_fence_driver_process(). If a fence never reaches that path,
such as it is already signaled when created, so we need to explicitly release
those fences in that case.

v2: use a list(list_cut_before) for managing the signal userq driver fences.(Christian)
    Link: https://patchwork.freedesktop.org/patch/718078/?series=164763&rev=2
