There may be a potential integer overflow issue in
_dpu_core_perf_calc_clk(). crtc_clk is defined as u64, while
mode->vtotal, mode->hdisplay, and drm_mode_vrefresh(mode) are defined as
a smaller data type. The result of the calculation will be limited to
"int" in this case without correct casting. In screen with high
resolution and high refresh rate, integer overflow may happen.
So, we recommend adding an extra cast to prevent potential
integer overflow.

[ Upstream commit fadcc3ab13 ]
Change idle freq clamping back to the direct method, bypassing PM QoS
requests. The problem with using PM QoS requests is they call
(indirectly) the governors ->get_target_freq() which goes thru a
get_dev_status() cycle. The problem comes when the GPU becomes active
again and we remove the idle-clamp request, we go through another
get_dev_status() cycle for the period that the GPU has been idle, which
triggers the governor to lower the target freq excessively.
This partially reverts commit 7c0ffcd40b ("drm/msm/gpu: Respect PM QoS
constraints"), but preserves the use of boost QoS request, so that it
will continue to play nicely with other QoS requests such as a cooling
device. This also mostly undoes commit 78f815c1cf ("drm/msm: return the

[ Upstream commit 87cb58aebdf7005661a07e9fd5a900f924d48c75 ]
The callsite layout for arm64 fentry is:
mov x9, lr
nop
When a bpf prog is attached, the nop instruction is patched to a call
to bpf trampoline:
mov x9, lr
bl <bpf trampoline>
So two return addresses are passed to bpf trampoline: the return address
for the traced function/prog, stored in x9, and the return address for
the bpf trampoline itself, stored in lr. To obtain a full and accurate
call stack, the bpf trampoline constructs two fake function frames using
x9 and lr.
However, struct_ops progs are invoked directly as function callbacks,
meaning that x9 is not set as it is in the fentry callsite. In this case,
the frame constructed using x9 is garbage. The following stack trace for
struct_ops, captured by perf sampling, illustrates this issue, where
tcp_ack+0x404 is a garbage frame:
ffffffc0801a04b4 bpf_prog_50992e55a0f655a9_bpf_cubic_cong_avoid+0x98 (bpf_prog_50992e55a0f655a9_bpf_cubic_cong_avoid)
ffffffc0801a228c [unknown] ([kernel.kallsyms]) // bpf trampoline
ffffffd08d362590 tcp_ack+0x798 ([kernel.kallsyms]) // caller for bpf trampoline

ffffffd08d378630 tcp_v4_rcv+0xeb8 ([kernel.kallsyms])
To fix it, construct only one frame using lr for struct_ops.
The above stack trace also indicates that there is no kernel symbol for
struct_ops bpf trampoline. This will be addressed in a follow-up patch.

[ Upstream commit 2d343723c7e1f9f6d64f721f07cfdfc2993758d1 ]
When a display controller driver uses DRM_BRIDGE_ATTACH_NO_CONNECTOR,
tc358767 will behave properly and skip the creation of the connector.
However, tc_get_display_props(), which is used to find out about the DP
monitor and link, is only called from two places: .atomic_enable() and
tc_connector_get_modes(). The latter is only used when tc358767 creates
its own connector, i.e. when DRM_BRIDGE_ATTACH_NO_CONNECTOR is _not_
set.
Thus, the driver never finds out the link properties before get_edid()
is called. With num_lanes of 0 and link_rate of 0 there are not many
valid modes...
Fix this by adding tc_get_display_props() call at the beginning of
get_edid(), so that we have up to date information before looking at the
modes.

Libbpf pre-1.0 had a legacy logic of allowing singular non-annotated
(i.e., not having explicit SEC() annotation) function to be treated as
sole entry BPF program (unless there were other explicit entry
programs).
This behavior was dropped during libbpf 1.0 transition period (unless
LIBBPF_STRICT_SEC_NAME flag was unset in libbpf_mode). When 1.0 was
released and all the legacy behavior was removed, the bug slipped
through leaving this legacy behavior around.
Fix this for good, as it actually causes very confusing behavior if BPF
object file only has subprograms, but no entry programs.

test_progs uses glibc specific functions backtrace() and
backtrace_symbols_fd() to print backtrace in case of SIGSEGV.
Recent commit (see fixes) updated test_progs.c to define stub versions
of the same functions with attriubte "weak" in order to allow linking
test_progs against musl libc. Unfortunately this broke the backtrace
handling for glibc builds.
As it turns out, glibc defines backtrace() and backtrace_symbols_fd()
as weak:
$ llvm-readelf --symbols /lib64/libc.so.6 \
| grep -P '( backtrace_symbols_fd| backtrace)$'
4910: 0000000000126b40 161 FUNC WEAK DEFAULT 16 backtrace
6843: 0000000000126f90 852 FUNC WEAK DEFAULT 16 backtrace_symbols_fd
So does test_progs:
$ llvm-readelf --symbols test_progs \
| grep -P '( backtrace_symbols_fd| backtrace)$'
2891: 00000000006ad190 15 FUNC WEAK DEFAULT 13 backtrace
11215: 00000000006ad1a0 41 FUNC WEAK DEFAULT 13 backtrace_symbols_fd
In such situation dynamic linker is not obliged to favour glibc
implementation over the one defined in test_progs.
Compiling with the following simple modification to test_progs.c
demonstrates the issue:
$ git diff
...

For example, the following boards using MT6359 PMIC:
- mt8192-asurada.dtsi
- mt8195-cherry.dtsi
These boards use the same definitions of 'dmic-mode' as other boards
using MT6358 PMIC. The meaning of '0' or '1' has been noted as comments
in the device trees.
Upon examining the code in [1] and [2], it was confirmed that the
definitions of 'dmic-mode' are consistent between "MT6359 PMIC" and
"MT6358 PMIC". Therefore, the DT Schema should be correct as is.

[ Upstream commit 52db16ec5bae7bd027804265b968259d1a6c3970 ]
In supported_vht_mcs_rate_nss2, the rate for MCS9 & VHT20 is defined as
{1560, 1733}, this does not align with firmware's definition and therefore
fails the verification in ath10k_mac_get_rate_flags_vht():
invalid vht params rate 1730 100kbps nss 2 mcs 9
and:
invalid vht params rate 1920 100kbps nss 2 mcs 9
Change it to {1730, 1920} to align with firmware to fix the issue.
Since ath10k_hw_params::supports_peer_stats_info is enabled only for
QCA6174, this change does not affect other chips.

[ Upstream commit cf1becb7f996a0a23ea2c270cf6bb0911ec3ca1a ]
We must first flush the MMU cache and then, flush the TLB, not the other
way around. Currently, we can see a race condition between the MMU cache
and the TLB when running multiple rendering processes at the same time.
This is evidenced by MMU errors triggered by the IRQ.
Fix the MMU flush order by flushing the MMU cache and then the TLB.
Also, in order to address the race condition, wait for the MMU cache flush
to finish before starting the TLB flush.

smatch reports:
drivers/gpu/drm/omapdrm/dss/base.c:176 omapdss_device_disconnect() error: we previously assumed 'src' could be null (see line 169)
This code is mostly from a time when omapdrm had its own display device
model. I can't honestly remember the details, and I don't think it's
worth digging in deeply into that for a legacy driver.
However, it looks like we only call omapdss_device_disconnect() and
omapdss_device_connect() with NULL as the src parameter. We can thus
drop the src parameter from both functions, and fix the smatch warning.
I don't think omapdss_device_disconnect() ever gets NULL for the dst
parameter (if it did, we'd crash soon after returning from the
function), but I have kept the !dst check, just in case, but I added a
WARN_ON() there.
Also, if the dst parameter can be NULL, we can't always get the struct
dss_device pointer from dst->dss (which is only used for a debug print).
To make sure we can't hit that issue, do it similarly to the
omapdss_device_connect() function: add 'struct dss_device *dss' as the
first parameter, so that we always have it regardless of the dst.

conn_rsp_epid to htc_connect_service() to prevent the bug from occurring.

When factoring out __vc4_hvs_stop_channel, the logic got inverted from
if (condition)
// stop channel
to
if (condition)
goto out
//stop channel
out:
and also changed the exact register writes used to stop the channel.
Correct the logic so that the channel is actually stopped, and revert
to the original register writes.
