Thiago Padilha	6c487e2f79	server: enforce prompt cache RAM limit (#25070 ) Before this commit, --cache-ram was not a hard limit: - The cache always kept at least one entry, even if that entry exceeded the RAM/token limits. - Old entries were only evicted for the RAM/token limits after saving the new one, which could cause the cache to temporarily exceed the RAM/token limits even if individual entries were below the limit. Now, ensure that the RAM limit is strict with these changes: - Skip saving state to cache if by itself it exceeds the RAM limit. - Evict old entries as necessary to make the new entry fit. Additionally, token-limit cleanup may now evict the last remaining cache entry instead of always preserving one.	2026-07-07 15:24:35 +02:00

Decline it in supports_op; prefill stays on the GPU. * opencl: compile MQ_GQA=8 FA kernels in a minimal program The full program compiled with -D MQ_GQA=8 runs the Adreno compiler out of memory at DK>=256. Only the vec_mq kernels are used from this program, so compile it with FA_MQ_ONLY, which excludes everything else. Also include the program name in the compile error log. * opencl: remove stray token in flash_attn_f32_f16.cl A stray "." broke the f32_f16 program build. * opencl: split f16-KV FA decode finer (FD_KV_PER_SPLIT_F16) The 2048 default under-fills the GPU on single-query f16-KV decode; use 512 for f16 KV to get more splits.
