Ma Jun aa665c3a2a Revert "drm/amd/amdgpu: Fix potential ioremap() memory leaks in amdgpu_device_init()"
commit 03c6284df1 upstream.

This patch causes the following iounmap erorr and calltrace
iounmap: bad address 00000000d0b3631f

The original patch was unjustified because amdgpu_device_fini_sw() will
always cleanup the rmmio mapping.

This reverts commit eb4f139888.

Dave Airlie 4d5ee18247 nouveau: fix devinit paths to only handle display on GSP.
[ Upstream commit 718c4fb221 ]

This reverts:
nouveau/gsp: don't check devinit disable on GSP.
and applies a further fix.

It turns out the open gpu driver, checks this register,
but only for display.

Match that behaviour and in the turing path only disable
the display block. (ampere already only does displays).

Ahmad Rehman 4f8154f775 drm/amdgpu: Init zone device and drm client after mode-1 reset on reload
[ Upstream commit f679fd6057 ]

In passthrough environment, when amdgpu is reloaded after unload, mode-1
is triggered after initializing the necessary IPs, That init does not
include KFD, and KFD init waits until the reset is completed. KFD init
is called in the reset handler, but in this case, the zone device and
drm client is not initialized, causing app to create kernel panic.

v2: Removing the init KFD condition from amdgpu_amdkfd_drm_client_create.
As the previous version has the potential of creating DRM client twice.

v3: v2 patch results in SDMA engine hung as DRM open causes VM clear to SDMA
before SDMA init. Adding the condition to in drm client creation, on top of v1,
to guard against drm client creation call multiple times.

Shradha Gupta 956d8407bf drm: Check polling initialized before enabling in drm_helper_probe_single_connector_modes
commit 048a36d8a6 upstream.

In function drm_helper_probe_single_connector_modes() when we enable
polling again, if it is already uninitialized, a warning is reported.
This patch fixes the warning message by checking if poll is initialized
before enabling it.

Shradha Gupta 18451798f4 drm: Check output polling initialized before disabling
[ Upstream commit 5abffb66d1 ]

In drm_kms_helper_poll_disable() check if output polling
support is initialized before disabling polling. If not flag
this as a warning.
Additionally in drm_mode_config_helper_suspend() and
drm_mode_config_helper_resume() calls, that re the callers of these
functions, avoid invoking them if polling is not initialized.
For drivers like hyperv-drm, that do not initialize connector
polling, if suspend is called without this check, it leads to
suspend failure with following stack

This ensures that the memory mapped by ioremap for adev->rmmio, is

due to an error, the memory is unmapped. If the function completes
successfully, the memory remains mapped.

Originally, PMFW said min FCLK is 300Mhz, but min DCFCLK can be increased
to 400Mhz because min FCLK is now 600Mhz so FCLK >= 1.5 * DCFCLK hardware

Vignesh Raman 1d6a47d490 drm/ci: uprev mesa version: fix kdl commit fetch
[ Upstream commit d315a68e94 ]

build-kdl.sh was doing a `clone --depth 1` of the default branch,
then checking out a commit that might not be the latest of that
branch, resulting in container build error.

https://gitlab.freedesktop.org/mesa/mesa/-/commit/5efa4d56 fixes
kdl commit fetch issue. Uprev mesa in drm-ci to fix this.

This commit updates the kernel tag and adds .never-post-merge-rules
due to the mesa uprev. It also fixes an issue where the virtio-gpu
pipeline was not getting created with the mesa uprev.

This happens because, although `prepare_fb` and `cleanup_fb` are
perfectly balanced, we cannot guarantee consistency in the check
plane->state->fb == state->fb. This means that sometimes we can increase
the refcount in `prepare_fb` and don't decrease it in `cleanup_fb`. The
opposite can also be true.

In fact, the struct drm_plane .state shouldn't be accessed directly
but instead, the `drm_atomic_get_new_plane_state()` helper function should
be used. So, we could stick to this check, but using
`drm_atomic_get_new_plane_state()`. But actually, this check is not really
needed. We can increase and decrease the refcount symmetrically without
problems.

This is going to make the code more simple and consistent.

Thomas Hellström b8236cdf0b drm/xe: Use ring ops TLB invalidation for rebinds
commit 3c88b8f471 upstream.

For each rebind we insert a GuC TLB invalidation and add a
corresponding unordered TLB invalidation fence. This might
add a huge number of TLB invalidation fences to wait for so
rather than doing that, defer the TLB invalidation to the
next ring ops for each affected exec queue. Since the TLB
is invalidated on exec_queue switch, we need to invalidate
once for each affected exec_queue.

v2:
- Simplify if-statements around the tlb_flush_seqno.
  (Matthew Brost)
- Add some comments and asserts.

commit 51bc63392e upstream.

The MST code currently assumes that glk+ already supports MST+DSC,
which is incorrect. We need to check for TGL+ actually. ICL does
support SST+DSC, but supposedly it can't do MST+FEC which will
also rule out MST+DSC.

Note that a straight TGL+ check doesn't work here because DSC
support can get fused out, so we do need to also check 'has_dsc'.

Imre Deak cae44b9daa drm/i915/dp: Fix DSC state HW readout for SST connectors
[ Upstream commit d725ce9d7c ]

Commit 0848814aa2 ("drm/i915/dp: Fix connector DSC HW state readout")
moved the DSC HW state readout to a connector specific hook, however

Dave Airlie 0c16020d2b nouveau/uvmm: fix addr/range calcs for remap operations
[ Upstream commit be141849ec ]

dEQP-VK.sparse_resources.image_rebind.2d_array.r64i.128_128_8
was causing a remap operation like the below.

op_remap: prev: 0000003fffed0000 00000000000f0000 00000000a5abd18a 0000000000000000

op_remap: unmap: 0000003fffed0000 0000000000100000 0
op_map: map: 0000003ffffc0000 0000000000010000 000000005b1ba33c 00000000000e0000

This was resulting in an unmap operation from 0x3fffed0000+0xf0000, 0x100000
which was corrupting the pagetables and oopsing the kernel.

Fixes the prev + unmap range calcs to use start/end and map back to addr/range.

Arnd Bergmann 041f548142 kbuild: make -Woverride-init warnings more consistent
[ Upstream commit c40845e319 ]

The -Woverride-init warn about code that may be intentional or not,
but the inintentional ones tend to be real bugs, so there is a bit of
disagreement on whether this warning option should be enabled by default
and we have multiple settings in scripts/Makefile.extrawarn as well as
individual subsystems.

Older versions of clang only supported -Wno-initializer-overrides with
the same meaning as gcc's -Woverride-init, though all supported versions
now work with both. Because of this difference, an earlier cleanup of
mine accidentally turned the clang warning off for W=1 builds and only
left it on for W=2, while it's still enabled for gcc with W=1.

There is also one driver that only turns the warning off for newer
versions of gcc but not other compilers, and some but not all the
Makefiles still use a cc-disable-warning conditional that is no
longer needed with supported compilers here.

Address all of the above by removing the special cases for clang
and always turning the warning off unconditionally where it got
in the way, using the syntax that is supported by both compilers.

Set dtbclk_en to true on boot so that disable message is sent during first

Brian Welty 242e831270 drm/xe: Add exec_queue.sched_props.job_timeout_ms
[ Upstream commit 6ae24344e2 ]

The purpose here is to allow to optimize exec_queue_set_job_timeout()
in follow-on patch.  Currently it does q->ops->set_job_timeout(...).
But we'd like to apply exec_queue_user_extensions much earlier and
q->ops cannot be called before __xe_exec_queue_init().

It will be much more efficient to instead only have to set
q->sched_props.job_timeout_ms when applying user extensions. That value
will then be used during q->ops->init().

Vitaly Prosyak 54b5b7275d drm/sched: fix null-ptr-deref in init entity
commit f34e8bb7d6 upstream.

The bug can be triggered by sending an amdgpu_cs_wait_ioctl
to the AMDGPU DRM driver on any ASICs with valid context.
The bug was reported by Joonkyo Jung <joonkyoj@yonsei.ac.kr>.
For example the following code:

    static void Syzkaller2(int fd)
    {
	union drm_amdgpu_ctx arg1;
	union drm_amdgpu_wait_cs arg2;

	arg1.in.op = AMDGPU_CTX_OP_ALLOC_CTX;
	ret = drmIoctl(fd, 0x140106442 /* amdgpu_ctx_ioctl */, &arg1);

	arg2.in.handle = 0x0;
	arg2.in.timeout = 0x2000000000000;
	arg2.in.ip_type = AMD_IP_VPE /* 0x9 */;
	arg2->in.ip_instance = 0x0;
	arg2.in.ring = 0x0;
	arg2.in.ctx_id = arg1.out.alloc.ctx_id;

	drmIoctl(fd, 0xc0206449 /* AMDGPU_WAIT_CS * /, &arg2);
    }

The ioctl AMDGPU_WAIT_CS without previously submitted job could be assumed that
the error should be returned, but the following commit 1decbf6bb0
modified the logic and allowed to have sched_rq equal to NULL.

As a result when there is no job the ioctl AMDGPU_WAIT_CS returns success.
The change fixes null-ptr-deref in init entity and the stack below demonstrates
the error condition:

Vitaly Prosyak 22f665ecfd drm/amdgpu: fix use-after-free bug
commit 22207fd5c8 upstream.

The bug can be triggered by sending a single amdgpu_gem_userptr_ioctl
to the AMDGPU DRM driver on any ASICs with an invalid address and size.
The bug was reported by Joonkyo Jung <joonkyoj@yonsei.ac.kr>.
For example the following code:

static void Syzkaller1(int fd)
{
	struct drm_amdgpu_gem_userptr arg;
	int ret;

	arg.addr = 0xffffffffffff0000;
	arg.size = 0x80000000; /*2 Gb*/
	arg.flags = 0x7;
	ret = drmIoctl(fd, 0xc1186451/*amdgpu_gem_userptr_ioctl*/, &arg);
}

Due to the address and size are not valid there is a failure in
amdgpu_hmm_register->mmu_interval_notifier_insert->__mmu_interval_notifier_insert->
check_shl_overflow, but we even the amdgpu_hmm_register failure we still call
amdgpu_hmm_unregister into  amdgpu_gem_object_free which causes access to a bad address.
The following stack is below when the issue is reproduced when Kazan is enabled:

Hamza Mahfooz 4acef16fe2 drm/amd/display: fix IPX enablement
commit 1202f794cd upstream.

We need to re-enable idle power optimizations after entering PSR. Since,
we get kicked out of idle power optimizations before entering PSR
(entering PSR requires us to write to DCN registers, which isn't allowed
while we are in IPS).

Fixes: a9b1a4f684 ("drm/amd/display: Add more checks for exiting idle in DC")

Roman Li f6e163e9c3 drm/amd/display: Fix bounds check for dcn35 DcfClocks
commit 2f10d4a51b upstream.

[Why]
NumFclkLevelsEnabled is used for DcfClocks bounds check
instead of designated NumDcfClkLevelsEnabled.
That can cause array index out-of-bounds access.

[How]
Use designated variable for dcn35 DcfClocks bounds check.
