drm/amdkfd: option to disable system mem limit

If multiple process share system memory through /dev/shm, KFD allocate
memory should not fail if it reaches the system memory limit because
one copy of physical system memory are shared by multiple process.

Add module parameter no_system_mem_limit to provide user option to
disable system memory limit check at runtime using sysfs or during
driver module init using kernel boot argument. By default the system
memory limit is on.

Print out debug message to warn user if KFD allocate memory failed
because system memory reaches limit.

drm/amd/display: Separate pipe disconnect from rest of progrmaming

[Why]
When changing pixel formats for HDR (e.g. ARGB -> FP16)
there are configurations that change from 2 pipes to 1 pipe.
In these cases, it seems that disconnecting MPCC and doing
a surface update at the same time(after unlocking) causes
some registers to be updated slightly faster than others
after unlocking (e.g. if the pixel format is updated to FP16
before the new surface address is programmed, we get
corruption on the screen because the pixel formats aren't
matching). We separate disconnecting MPCC from the rest
of the pipe programming sequence to prevent this.

[How]
Move MPCC disconnect into separate operation than the
rest of the pipe programming.

[why]
There's currently no method to enable multi-stream synchronization from

[how]
Add a debugfs entry that controls a new DM debug option,
"force_timing_sync". This debug option will set on any newly created
stream following the change to the debug option.
Expose a new interface from DC that performs the timing sync and a helper
to the "force_timing_sync" debugfs that iterates over the current streams
and modifies the current synchornization state and grouping.

Example usage to force a resync (from an X based desktop):

During driver's probe, when it hits bad gpu tag in eeprom i2c
init calling(the tag was set when reported bad page reaches
bad page threshold in last driver's working loop), there are
some strategys to deal with the cases:

1. when the module parameter amdgpu_bad_page_threshold = 0,
that means page retirement feature is disabled, so just resetting
the eeprom is fine.
2. When amdgpu_bad_page_threshold is not 0, and moreover, user
sets one bigger valid data in order to make current boot up
succeeds, correct eeprom header tag and do not break booting.
3. For other cases, driver's probe will be broken.

v3: Use dev_info/dev_err to print PCI device information, which

drm/amdgpu: fix PSP autoload twice in FLR

Assigning false to block->status.hw overwrites PSP's previous
hardware status, which causes the PSP to Resume operation after
hardware init.

Remove this assignment and let the PSP execute Resume operation
when it is told to.

v2: Remove the braces.
v3: Modify the description.

drm/amdgpu/dc: Stop dma_resv_lock inversion in commit_tail

Trying to grab dma_resv_lock while in commit_tail before we've done
all the code that leads to the eventual signalling of the vblank event
(which can be a dma_fence) is deadlock-y. Don't do that.

Here the solution is easy because just grabbing locks to read
something races anyway. We don't need to bother, READ_ONCE is
equivalent. And avoids the locking issue.

v2: Also take into account tmz_surface boolean, plus just delete the
old code.

drm/amdgpu: Prevent kernel-infoleak in amdgpu_info_ioctl()

Compiler leaves a 4-byte hole near the end of `dev_info`, causing
amdgpu_info_ioctl() to copy uninitialized kernel stack memory to userspace
when `size` is greater than 356.

In 2015 we tried to fix this issue by doing `= {};` on `dev_info`, which
unfortunately does not initialize that 4-byte hole. Fix it by using
memset() instead.

drm/amd/display: Clear dm_state for fast updates

This patch fixes a race condition that causes a use-after-free during
amdgpu_dm_atomic_commit_tail. This can occur when 2 non-blocking commits
are requested and the second one finishes before the first. Essentially,
this bug occurs when the following sequence of events happens:

1. Non-blocking commit #1 is requested w/ a new dm_state #1 and is
deferred to the workqueue.

2. Non-blocking commit #2 is requested w/ a new dm_state #2 and is
deferred to the workqueue.

3. Commit #2 starts before commit #1, dm_state #1 is used in the
commit_tail and commit #2 completes, freeing dm_state #1.

4. Commit #1 starts after commit #2 completes, uses the freed dm_state
1 and dereferences a freelist pointer while setting the context.

Since this bug has only been spotted with fast commits, this patch fixes
the bug by clearing the dm_state instead of using the old dc_state for
fast updates. In addition, since dm_state is only used for its dc_state
and amdgpu_dm_atomic_commit_tail will retain the dc_state if none is found,
removing the dm_state should not have any consequences in fast updates.

This use-after-free bug has existed for a while now, but only caused a
noticeable issue starting from 5.7-rc1 due to 3202fa62f ("slub: relocate
freelist pointer to middle of object") moving the freelist pointer from
dm_state->base (which was unused) to dm_state->context (which is
dereferenced).

drm/amd/display: dchubbub p-state warning during surface planes switch

[Why]
ramp_up_dispclk_with_dpp is to change dispclk, dppclk and dprefclk
according to bandwidth requirement. call stack: rv1_update_clocks -->
update_clocks --> dcn10_prepare_bandwidth / dcn10_optimize_bandwidth
--> prepare_bandwidth / optimize_bandwidth. before change dcn hw,
prepare_bandwidth will be called first to allow enough clock,
watermark for change, after end of dcn hw change, optimize_bandwidth
is executed to lower clock to save power for new dcn hw settings.

below is sequence of commit_planes_for_stream:
step 1: prepare_bandwidth - raise clock to have enough bandwidth
step 2: lock_doublebuffer_enable
step 3: pipe_control_lock(true) - make dchubp register change will
not take effect right way
step 4: apply_ctx_for_surface - program dchubp
step 5: pipe_control_lock(false) - dchubp register change take effect
step 6: optimize_bandwidth --> dc_post_update_surfaces_to_stream
for full_date, optimize clock to save power

at end of step 1, dcn clocks (dprefclk, dispclk, dppclk) may be
changed for new dchubp configuration. but real dcn hub dchubps are
still running with old configuration until end of step 5. this need
clocks settings at step 1 should not less than that before step 1.
this is checked by two conditions: 1. if (should_set_clock(safe_to_lower
, new_clocks->dispclk_khz, clk_mgr_base->clks.dispclk_khz) ||
new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz)
2. request_dpp_div = new_clocks->dispclk_khz > new_clocks->dppclk_khz

the second condition is based on new dchubp configuration. dppclk
for new dchubp may be different from dppclk before step 1.
for example, before step 1, dchubps are as below:
pipe 0: recout=(0,40,1920,980) viewport=(0,0,1920,979)
pipe 1: recout=(0,0,1920,1080) viewport=(0,0,1920,1080)
for dppclk for pipe0 need dppclk = dispclk

new dchubp pipe split configuration:
pipe 0: recout=(0,0,960,1080) viewport=(0,0,960,1080)
pipe 1: recout=(960,0,960,1080) viewport=(960,0,960,1080)
dppclk only needs dppclk = dispclk /2.

dispclk, dppclk are not lock by otg master lock. they take effect
after step 1. during this transition, dispclk are the same, but
dppclk is changed to half of previous clock for old dchubp
configuration between step 1 and step 6. This may cause p-state
warning intermittently.

[How]
for new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz, we
need make sure dppclk are not changed to less between step 1 and 6.
for new_clocks->dispclk_khz > clk_mgr_base->clks.dispclk_khz,
new display clock is raised, but we do not know ratio of
new_clocks->dispclk_khz and clk_mgr_base->clks.dispclk_khz,
new_clocks->dispclk_khz /2 does not guarantee equal or higher than
old dppclk. we could ignore power saving different between
dppclk = displck and dppclk = dispclk / 2 between step 1 and step 6.
as long as safe_to_lower = false, set dpclk = dispclk to simplify
condition check.

DC should sequence this.

Note that DC will not re-enter idle optimized state on its own, it is only
responsible for catching out of sequence calls. It is still DM
responsibility to sequence appropriate for optimized power, but this change
removes the requirement for DM to cover the .1% case.

drm/amd/display: dc/clk_mgr: add support for SI parts (v2)

(v1) Changelog

[Why]
After commit c69dd2d "drm/amd/display: Refactor clk_mgr functions"
dc/clk_mgr requires these changes to add SI parts support
Necessary to avoid hitting default: ASSERT(0); /* Unknown Asic */
that would cause kernel freeze

[How]
Add case statement for FAMILY_SI chipsets

(v2) Changelog

[Why]
DCE6 has no DPREFCLK_CNTL register

[How]
Add DCE6 specific macros definitions for CLK registers and masks
Add DCE6 specific dce60/dce60_clk_mgr.c for DCE6 customization
Code style: reuse all the public functions in dce100/dce_clk_mgr.h header
Code style: use dce60_* static functions as per other DCE implementations
Add dce60_get_dp_ref_freq_khz() w/o using DPREFCLK_CNTL register
Use dce60_get_dp_ref_freq_khz() function in dce60_funcs
Add DCE6 specific dce60_clk_mgr_construct
dc/clk_mgr/dce_clk_mgr.c: use dce60_clk_mgr_construct for FAMILY_SI chipsets
Add Makefile rules for dce60_clk_mgr.o target conditional to CONFIG_DRM_AMD_DC_SI

drm/amd/display: amdgpu_dm: add SI support (v4)

[Why]
amdgpu_dm.c requires changes for SI chipsets init and irq handlers registration

[How]
SI support: load_dmcu_fw(), amdgpu_dm_initialize_drm_device(), dm_early_init()
Add DCE6 specific dce60_register_irq_handlers() function

(v1) NOTE: As per Kaveri and older amdgpu.dc=1 kernel cmdline is required

(v2) fix for bc011f9 ("drm/amdgpu: Change SI/CI gfx/sdma/smu init sequence")
     remove CHIP_HAINAN support since it does not have physical DCE6 module

(v3) fix vblank irq support for DCE6 using ad hoc dce60_register_irq_handlers()
     replicating for vblank irq the behavior of dce110_register_irq_handlers()
     as per commit b57de80 ("drm/amd/display: Register on VLBLANK ISR.")

(v4) updated due to following kernel 5.2 commit:
     b2fddb13 ("drm/amd/display: Drop underlay plane support")
