+Use kvfree() to fix the following Coccinelle/coccicheck warning reported
+by kfree_mismatch.cocci:
+
+ WARNING kvmalloc is used to allocate this memory at line 10398

+Subject: drm/amd/display: Don't overclock DCE 6 by 15%
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Timur Kristóf <timur.kristof@gmail.com>
+
+commit cb7b7ae53b557d168b4af5cd8549f3eff920bfb5 upstream.
+
+The extra 15% clock was added as a workaround for a Polaris issue
+which uses DCE 11, and should not have been used on DCE 6 which
+is already hardcoded to the highest possible display clock.
+Unfortunately, the extra 15% was mistakenly copied and kept
+even on code paths which don't affect Polaris.
+
+This commit fixes that and also adds a check to make sure
+not to exceed the maximum DCE 6 display clock.
+
+Fixes: 8cd61c313d8b ("drm/amd/display: Raise dispclk value for Polaris")
+Fixes: dc88b4a684d2 ("drm/amd/display: make clk mgr soc specific")

+Subject: drm/amd/display: Fix DP audio DTO1 clock source on DCE 6.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Timur Kristóf <timur.kristof@gmail.com>
+
+commit 297a4833a68aac3316eb808b4123eb016ef242d7 upstream.
+
+On DCE 6, DP audio was not working. However, it worked when an
+HDMI monitor was also plugged in.
+
+Looking at dce_aud_wall_dto_setup it seems that the main
+difference is that we use DTO1 when only DP is plugged in.
+
+When programming DTO1, it uses audio_dto_source_clock_in_khz
+which is set from get_dp_ref_freq_khz
+
+The dce60_get_dp_ref_freq_khz implementation looks incorrect,
+because DENTIST_DISPCLK_CNTL seems to be always zero on DCE 6,
+so it isn't usable.
+I compared dce60_get_dp_ref_freq_khz to the legacy display code,
+specifically dce_v6_0_audio_set_dto, and it turns out that in
+case of DCE 6, it needs to use the display clock. With that,
+DP audio started working on Pitcairn, Oland and Cape Verde.
+
+However, it still didn't work on Tahiti. Despite having the
+same DCE version, Tahiti seems to have a different audio device.
+After some trial and error I realized that it works with the
+default display clock as reported by the VBIOS, not the current
+display clock.
+
+The patch was tested on all four SI GPUs:
+
+* Pitcairn (DCE 6.0)
+* Oland (DCE 6.4)
+* Cape Verde (DCE 6.0)
+* Tahiti (DCE 6.0 but different)
+
+The testing was done on Samsung Odyssey G7 LS28BG700EPXEN on
+each of the above GPUs, at the following settings:
+
+* 4K 60 Hz
+* 1080p 60 Hz
+* 1080p 144 Hz

+Subject: drm/amd/display: Fix fractional fb divider in set_pixel_clock_v3
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Timur Kristóf <timur.kristof@gmail.com>
+
+commit 10507478468f165ea681605d133991ed05cdff62 upstream.
+
+For later VBIOS versions, the fractional feedback divider is
+calculated as the remainder of dividing the feedback divider by
+a factor, which is set to 1000000. For reference, see:
+- calculate_fb_and_fractional_fb_divider
+- calc_pll_max_vco_construct
+
+However, in case of old VBIOS versions that have
+set_pixel_clock_v3, they only have 1 byte available for the
+fractional feedback divider, and it's expected to be set to the
+remainder from dividing the feedback divider by 10.
+For reference see the legacy display code:
+- amdgpu_pll_compute
+- amdgpu_atombios_crtc_program_pll
+
+This commit fixes set_pixel_clock_v3 by dividing the fractional
+feedback divider passed to the function by 100000.

+Subject: drm/amd/display: Fix Xorg desktop unresponsive on Replay panel
+
+From: Tom Chung <chiahsuan.chung@amd.com>
+
+commit 66af73a1c319336694a8610fe4c2943f7b33066c upstream.
+
+[WHY & HOW]
+IPS & self-fresh feature can cause vblank counter resets between
+vblank disable and enable.
+It may cause system stuck due to wait the vblank counter.
+
+Call the drm_crtc_vblank_restore() during vblank enable to estimate
+missed vblanks by using timestamps and update the vblank counter in
+DRM.
+
+It can make the vblank counter increase smoothly and resolve this issue.
