2022-02-02drm/amd/display: Update watermark values for DCN301Agustin Gutierrez
[Why] There is underflow / visual corruption DCN301, for high bandwidth MST DSC configurations such as 2x1440p144 or 2x4k60. [How] Use up-to-date watermark values for DCN301.

2022-02-02drm/amdgpu: fix a potential GPU hang on cyan skillfishLang Yu
We observed a GPU hang when querying GMC CG state(i.e., cat amdgpu_pm_info) on cyan skillfish. Acctually, cyan skillfish doesn't support any CG features. Just prevent it from accessing GMC CG registers.

2022-02-02drm/amd: Only run s3 or s0ix if system is configured properlyMario Limonciello
This will cause misconfigured systems to not run the GPU suspend routines. * In APUs that are properly configured system will go into s2idle. * In APUs that are intended to be S3 but user selects s2idle the GPU will stay fully powered for the suspend. * In APUs that are intended to be s2idle and system misconfigured the GPU will stay fully powered for the suspend. * In systems that are intended to be s2idle, but AMD dGPU is also present, the dGPU will go through S3 Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2022-01-31drm/amd: Warn users about potential s0ix problemsMario Limonciello
On some OEM setups users can configure the BIOS for S3 or S2idle. When configured to S3 users can still choose 's2idle' in the kernel by using `/sys/power/mem_sleep`. Before commit 6dc8265f9803 ("drm/amdgpu: always reset the asic in suspend (v2)"), the GPU would crash. Now when configured this way, the system should resume but will use more power. As such, adjust the `amdpu_acpi_is_s0ix function` to warn users about potential power consumption issues during their first attempt at suspending.

Record the start_time for a bio but defer the starting block core's IO accounting until after IO is submitted using bio_start_io_acct_time().

2022-01-27drm/vmwgfx: Fix stale file descriptors on failed usercopyMathias Krause
A failing usercopy of the fence_rep object will lead to a stale entry in the file descriptor table as put_unused_fd() won't release it. This enables userland to refer to a dangling 'file' object through that still valid file descriptor, leading to all kinds of use-after-free exploitation scenarios. Fix this by deferring the call to fd_install() until after the usercopy has succeeded.

For Intel platform, it is required to configure PTP clock source prior PTP initialization in MAC. So, need to move ptp_clk_freq_config execution from stmmac_ptp_register() to stmmac_init_ptp().

In __pata_platform_probe(), devm_kzalloc() is assigned to ap->ops and there is a dereference of it right after that, which could introduce a NULL pointer dereference bug.

2022-01-26serial: core: Initialize rs485 RTS polarity already on probeLukas Wunner
RTS polarity of rs485-enabled ports is currently initialized on uart open via: tty_port_open() tty_port_block_til_ready() tty_port_raise_dtr_rts() # if (C_BAUD(tty)) uart_dtr_rts() uart_port_dtr_rts() There's at least three problems here: First, if no baud rate is set, RTS polarity is not initialized. That's the right thing to do for rs232, but not for rs485, which requires that RTS is deasserted unconditionally. Second, if the DeviceTree property "linux,rs485-enabled-at-boot-time" is present, RTS should be deasserted as early as possible, i.e. on probe. Otherwise it may remain asserted until first open. Third, even though RTS is deasserted on open and close, it may subsequently be asserted by uart_throttle(), uart_unthrottle() or uart_set_termios() because those functions aren't rs485-aware. (Only uart_tiocmset() is.) To address these issues, move RTS initialization from uart_port_dtr_rts() to uart_configure_port(). Prevent subsequent modification of RTS polarity by moving the existing rs485 check from uart_tiocmget() to uart_update_mctrl(). That way, RTS is initialized on probe and then remains unmodified unless the uart transmits data. If rs485 is enabled at runtime (instead of at boot) through a TIOCSRS485 ioctl(), RTS is initialized by the uart driver's ->rs485_config() callback and then likewise remains unmodified. The PL011 driver initializes RTS on uart open and prevents subsequent modification in its ->set_mctrl() callback. That code is obsoleted by the present commit, so drop it.
