I would like to raise the issue of the cache again. As I wrote in a previous post, I use SET_MMU, in which I set myself also includes cache, please see the FRAGMA settings:
split_ram = yes
# "Pagesize" can be either 4k pages for 4k or 8k for ..eh .. 8k pages.
pagesize = 8k
# With the "CACR" variable you set the CACR cpu register.
# The Following Following are the flags you can use ...
# Edc - Enable Data Cache
# Over - No Allocate Mode (data cache)
# Esb - Enable Buffer Store
# Dpi - Disable CPUSH invalidation
# Foc - 1/2 cache operation mode enable (data cache)
# EBC - Enable Branch Cache
# Cabc - Clear all entries in the branch cache
# Cubc - Clear all user entries in the branch cache
# EIC - Enable Instruction cache
# Nai - No Allocation Mode (instruction cache)
# Fic - 1/2 cache operation mode enable (instruction cache)
CACR = Edc, Esb, EBC, Cabc, EIC
Recently I started MiNT at resolutions such as 800x600 allbo 1024x768 in 256 colors, what was my surprise as I noticed that the cache under MiNT system is switched on and test look very good. However, in the same configuration, the same ACCs, CPXs without MiNT.PRG in AUTO folder under system TOS cache is disabled. Completely I resigned from the file ACC HAdes_B3.ACC etc., because they cause system crashes
Whether it is possible that I must now use the ISA graphics card ?
What do you think abou it ?
Thanks, can you write how I should modify mint.cnf
