Re: [Intel-gfx] [PATCH] drm/i915/jsl: Split EHL/JSL platform info and PCI ids

On 07/10/2020 10:36, Tejas Upadhyay wrote:

Recently we came across requirement to identify EHL and JSL platform to program them differently. Thus Split the basic platform definition, macros, and PCI IDs to differentiate between EHL and JSL platforms. Also, IS_ELKHARTLAKE is replaced with IS_JSL_EHL everywhere.

Existance of IS_JSL_EHL (IS_JASPERLAKE || IS_ELKHARTLAKE), removal of IS_ELKHARTLAKE and absence of IS_JASPERLAKE is making me ask whether going the subplatform route would be useful or more handy in this case? Don't know how separate or close the platforms are, just mentioning the option in case it makes sense. (Like JASPERLAKE, subplatform ELKHARTLAKE.)
