Add: use PHY config from the next higher pixel clock on VU5A #363

Closed AreaScout closed 5 years ago

AreaScout commented 5 years ago

Description

The guessed PHY config taken for the pixel clock of 33900000 only can reach a frame rate of 56.89

Motivation and Context

Using the VU5A for emulation and gaming it is a real problem if the emulator try to hold 60 FPS and he can't, as we don't know whats really inside those 32 byte array I have taken the PHY config from the next higher pixel clock which then can reach a FPS of 64. With a FPS >= 60, emulators working way better !

How Has This Been Tested?

Thank you for the PR. :) Let us check it with our test environment and confirm it.

I've checked stability tests and confirmed its normal operation with VU5A. It must be better to run higher vsync 63.7Hz with 36MHz than the case of vsync 56.64Hz with 32MHz if Vu5A works with 36MHz condition. This commit will be merged soon.
