20 months agodrm/mediatek: dsi: Fix DSI RGB666 formats and definitions

drm/mediatek: dsi: Fix DSI RGB666 formats and definitions

[ Upstream commit fae6f815505301b92d9113764f4d76d0bfe45607 ]

The register bits definitions for RGB666 formats are wrong in multiple
ways: first, in the DSI_PS_SEL bits region, the Packed 18-bits RGB666
format is selected with bit 1, while the Loosely Packed one is bit 2,
and second - the definition name "LOOSELY_PS_18BIT_RGB666" is wrong
because the loosely packed format is 24 bits instead!

Either way, functions mtk_dsi_ps_control_vact() and mtk_dsi_ps_control()
do not even agree on the DSI_PS_SEL bit to set in DSI_PSCTRL: one sets
loosely packed (24) on RGB666, the other sets packed (18), and the other
way around for RGB666_PACKED.

Fixing this entire stack of issues is done in one go:
 - Use the correct bit for the Loosely Packed RGB666 definition
 - Rename LOOSELY_PS_18BIT_RGB666 to LOOSELY_PS_24BIT_RGB666
 - Change ps_bpp_mode in mtk_dsi_ps_control_vact() to set:
    - Loosely Packed, 24-bits for MIPI_DSI_FMT_RGB666
    - Packed, 18-bits for MIPI_DSI_FMT_RGB666_PACKED

In dvb_register_device, *pdvbdev is set equal to dvbdev, which is freed
in several error-handling paths. However, *pdvbdev is not set to NULL

        |-> dvb_unregister_device
              |-> dvb_remove_device
                    |-> dvb_device_put
                          |-> kref_put

When calling dvb_unregister_device, dmxdev->dvbdev (i.e. *pdvbdev in
dvb_register_device) could point to memory that had been freed in
dvb_register_device. Thereafter, this pointer is transferred to
kref_put and triggering a use-after-free.

20 months agoclk: samsung: exynos850: Propagate SPI IPCLK rate change

clk: samsung: exynos850: Propagate SPI IPCLK rate change

[ Upstream commit 67c15187d4910ee353374676d4dddf09d8cb227e ]

When SPI transfer is being prepared, the spi-s3c64xx driver will call
clk_set_rate() to change the rate of SPI source clock (IPCLK). But IPCLK
is a gate (leaf) clock, so it must propagate the rate change up the
clock tree, so that corresponding DIV clocks can actually change their
divider values. Add CLK_SET_RATE_PARENT flag to corresponding clocks for
all SPI instances in Exynos850 (spi_0, spi_1 and spi_2) to make it
possible. This change involves next clocks:

usi_spi_0:

    Clock                  Block       Div range
    --------------------------------------------
    gout_spi0_ipclk        CMU_PERI    -
    dout_peri_spi0         CMU_PERI    /1..32
    mout_peri_spi_user     CMU_PERI    -
    dout_peri_ip           CMU_TOP     /1..16

usi_cmgp0:

    Clock                  Block       Div range
    --------------------------------------------
    gout_cmgp_usi0_ipclk   CMU_CMGP    -
    dout_cmgp_usi0         CMU_CMGP    /1..32
    mout_cmgp_usi0         CMU_CMGP    -
    gout_clkcmu_cmgp_bus   CMU_APM     -
    dout_apm_bus           CMU_APM     /1..8

usi_cmgp1:

    Clock                  Block       Div range
    --------------------------------------------
    gout_cmgp_usi1_ipclk   CMU_CMGP    -
    dout_cmgp_usi1         CMU_CMGP    /1..32
    mout_cmgp_usi1         CMU_CMGP    -
    gout_clkcmu_cmgp_bus   CMU_APM     -
    dout_apm_bus           CMU_APM     /1..8

With input clock of 400 MHz, this scheme provides next IPCLK rate range,
for each SPI block:

    SPI0:   781 kHz ... 400 MHz
    SPI1/2: 1.6 MHz ... 400 MHz

Accounting for internal /4 divider in SPI blocks, and because the max
SPI frequency is limited at 50 MHz, it gives us next SPI SCK rates:

    SPI0:   200 kHz ... 49.9 MHz
    SPI1/2: 400 kHz ... 49.9 MHz

Which should cover all possible applications of SPI bus. Of course,
setting SPI frequency to values as low as 500 kHz will also affect the
common bus dividers (dout_apm_bus or dout_peri_ip), which in turn
effectively lowers the rates for all leaf bus clocks derived from those
dividers, like HSI2C and I3C clocks. But at least it gives the board
designer a choice, whether to keep all clocks (SPI/HSI2C/I3C) at high
frequencies, or make all those clocks have lower frequencies. Not
propagating the rate change to those common dividers would limit this
choice to "only high frequencies are allowed for SPI/HSI2C/I3C" option,
making the common dividers useless. This decision follows the "Worse is
better" approach, relying on the users/engineers to know the system
internals when working with such low-level features, instead of trying
to account for all possible use-cases.

jumping to the remove_group label in case rzg2l_map_add_config() failed.
But if that happens, the mutex will already be unlocked, thus this it will
lead to double mutex unlock operation. To fix this move the
rzg2l_map_add_config() call just after all the name argument is ready and
before the mutex is locked. There is no harm in doing this, as this only

perf pmu: Treat the msr pmu as software

[ Upstream commit 24852ef2e2d5c555c2da05baff112ea414b6e0f5 ]

The msr PMU is a software one, meaning msr events may be grouped
with events in a hardware context. As the msr PMU isn't marked as a
software PMU by perf_pmu__is_software, groups with the msr PMU in

may lead to multiplexing errors where a hardware event isn't
counted while the msr event, such as tsc, is. Fix all of this by
marking the msr PMU as software, which agrees with the driver.

the firmware paths are not available anymore at snd_sof_probe() time.

Precisely, fw_filename_prefix is set by sof_select_ipc_and_paths() via

but sof_init_environment() which calls this function was moved from

sof_select_ipc_and_paths().

The problem here is that amd_sof_acp_probe() uses fw_filename_prefix to
compute fw_code_bin and fw_data_bin paths, and because the field is not
yet initialized, the paths end up containing (null):

20 months agodm: call the resume method on internal suspend
Mikulas Patocka [Mon, 11 Mar 2024 14:06:39 +0000 (15:06 +0100)] 
dm: call the resume method on internal suspend

[ Upstream commit 65e8fbde64520001abf1c8d0e573561b4746ef38 ]

There is this reported crash when experimenting with the lvm2 testsuite.
The list corruption is caused by the fact that the postsuspend and resume
methods were not paired correctly; there were two consecutive calls to the
origin_postsuspend function. The second call attempts to remove the
"hash_list" entry from a list, while it was already removed by the first
call.

Fix __dm_internal_resume so that it calls the preresume and resume
methods of the table's targets.

If a preresume method of some target fails, we are in a tricky situation.
We can't return an error because dm_internal_resume isn't supposed to
return errors. We can't return success, because then the "resume" and
"postsuspend" methods would not be paired correctly. So, we set the
DMF_SUSPENDED flag and we fake normal suspend - it may confuse userspace
tools, but it won't cause a kernel crash.

20 months agodm raid: fix false positive for requeue needed during reshape
Ming Lei [Mon, 11 Mar 2024 17:42:55 +0000 (13:42 -0400)] 
dm raid: fix false positive for requeue needed during reshape

[ Upstream commit b25b8f4b8ecef0f48c05f0c3572daeabefe16526 ]

An empty flush doesn't have a payload, so it should never be looked at
when considering to possibly requeue a bio for the case when a reshape
is in progress.
