memalloc_nofs_save/restore are no longer sufficient to prevent recursive lock warnings when holding locks that can be taken in MMU notifiers. Use memalloc_noreclaim_save/restore instead.

dcn21_validate_bandwidth() calls functions that use floating point math. On my machine this sometimes results in simd exceptions when there are other FPU users such as KVM virtual machines running. The screen freezes completely in this case. Wrapping the function with DC_FP_START()/DC_FP_END() seems to solve the problem. This mirrors the approach used for dcn20_validate_bandwidth. Tested on a AMD Ryzen 7 PRO 4750U (Renoir). Bug: https://bugzilla.kernel.org/show_bug.cgi?id=206987Signed-off-by:

Fix potential integer overflow by casting actual_calculated_clock_100hz to u64, in order to give the compiler complete information about the proper arithmetic to use. Notice that such variable is used in a context that expects an expression of type u64 (64 bits, unsigned) and the following expression is currently being evaluated using 32-bit arithmetic: actual_calculated_clock_100hz * post_divider Fixes: 7a03fdf6 ("drm/amd/display: fix 64bit division issue on 32bit OS") Addresses-Coverity-ID: 1501691 ("Unintentional integer overflow") Signed-off-by:

This patch is to make the error log more clear for fine grain tuning function, it covers Raven/Raven2/Picasso/Renoir/Vangogh. The fine grain tuning function uses the sysfs file -- pp_od_clk_voltage, but only when another sysfs file -- power_dpm_force_performance_level is switched to "manual" mode, it is allowed to access "pp_od_clk_voltage".

It is possible for ret_vsnprintf to be assigned negative value in error cases. As an unsigned variable, negative values which are stored in their 2's complement form gets treated as a positive number. This will led to treating bad cases as good ones. eg: -1 gets stored as 0xFFFFFFFF on a 32 bit system Signed-off-by:

As a result, when there is a signature certificate error, mod_hdcp_hdcp2_validate_ake_cert would return the default status, which is success.

Implement hwmon API for reading/setting slow and fast PPT limit. APU power is managed to system-level requirements through the PPT (package power tracking) feature. PPT is intended to limit power to the requirements of the power source and could be dynamically updated to maximize APU performance within the system power budget. Here FAST_PPT_LIMIT manages the ~10 ms moving average of APU power, while SLOW_PPT_LIMIT manages the configurable, thermally significant moving average of APU power (default ~5000 ms). User could read slow/fast ppt limit using command "cat power*_cap" or "sensors" in the hwmon device directory. User could adjust values of slow/fast ppt limit as needed depending on workloads through command "echo ## > power*_cap". Example: $ echo 15000000 > power1_cap $ echo 18000000 > power2_cap $ sensors amdgpu-pci-0300 Adapter: PCI adapter slowPPT: 9.04W (cap = 15.00 W) fastPPT: 9.04W (cap = 18.00 W) v2: align with existing interfaces for the getting/setting of PPT limits. Encode the upper 8 bits of limit value to distinguish slow and fast power limit type. Signed-off-by:Xiaomeng Hou <Xiaomeng.Hou@amd.com> Reviewed-by:
