What options does shikigva=60 enable ?
According to WEG sources, the value of 60 is not possible:
private:
// Aside generic DRM unlock patches, which are always on, Shiki also provides a set of patches
// to workaround various issues with hardware video acceleration support.
// These are set as a shikigva boot-arg bitmask.
// For example, to enable ForceOnlineRenderer, ExecutableWhitelist, and ReplaceBoardID
// you sum 1 + 8 + 32 = 41 -> and pass shikigva=41.
enum ShikiGVAPatches {
// Remove forceOfflineRenderer from AppleGVA Info.plist.
// This is required to allow hardware acceleration on several mac models with discrete GPUs
// when only IGPU is available.
// See /System/Library/PrivateFrameworks/AppleGVA.framework/Resources/Info.plist for more details.
ForceOnlineRenderer = 1,
// Remve hweBGRA from AppleGVA Info.plist.
// hweBGRA is not supported by NVIDIA GPUs, so the patch is sometimes required when using NVIDIA
// in a mac model meant to be used with AMD or Intel.
// See /System/Library/PrivateFrameworks/AppleGVA.framework/Resources/Info.plist for more details.
AllowNonBGRA = 2,
// Prior to 10.13.4 certain GPU+CPU combinations were not meant to provide hardware acceleration and had to be patched.
// The overall problematic configuration list is: NVIDIA+BDW, NVIDIA+SKL, NVIDIA+KBL, AMD+IVB, NVIDIA+SNB.
// Enabled automatically if shikigva is *NOT* passed on 10.13.3 and earlier. All are fixed in 10.13.4.
ForceCompatibleRenderer = 4,
// Unlike 10.12.6 without security updates and earlier, on 10.13 and latest 10.12.6 AppleGVA patches
// do not apply to all processes, and each process needs to be patched explicitly. This is a bug
// in Lilu, which needs to be explored and fixed. For now this bit ensures that the processes present
// in WHITELIST section of Patches.plist will definitely get the fixes even on 10.13 and 10.12.6.
// On 10.12.6 and 10.13 this must be used if any of the following bits are used:
// - ForceOnlineRenderer
// - AllowNonBGRA
// - ForceCompatibleRenderer
// - ReplaceBoardID
// - FixSandyBridgeClassName
// It is enabled automatically on 10.12 and 10.13 if shikigva is *NOT* passed and ForceCompatibleRenderer or
// FixSandyBridgeClassName are automatically enabled.
AddExecutableWhitelist = 8,
DisabledUnused16 = 16,
// Replace board-id used by AppleGVA by a different board-id.
// Sometimes it is feasible to use different GPU acceleration settings from the main mac model.
// By default Mac-27ADBB7B4CEE8E61 (iMac14,2) will be used, but you can override this via shiki-id boot-arg.
// See /System/Library/PrivateFrameworks/AppleGVA.framework/Resources/Info.plist for more details.
ReplaceBoardID = 32,
// Attempt to support fps.1_0 (FairPlay 1.0) in Safari.
// This should technically fix some very old streaming services in Safari, which rely on FairPlay DRM
// similar to the one found in iTunes. Newer streaming services require FairPlay 2.0, which is hardware-only,
// so nothing could be done about them.
// Another way to enable this is to pass -shikifps boot argument.
UnlockFP10Streaming = 64,
