This PR prevents max_num_batched_tokens from limiting decode buckets, as decode buckets should be limited by number of blocks, not by max_num_batched_tokens.
Ports #97 to habana_main
Refactors BGMV implementation from gather based to mask-based to optimize performance and reduce device memory usage.
Use all possible slot values for dummy blocks to avoid caching issues.
With PT_COMPILE_ONLY_MODE flag, graphs can be compiled without performing synLaunch. The flag has been added to the warmup phase to decrease its execution time.
This fixes a very silly issue where mismatching values of `warmup_mode` flag could cause graph recompilations and eventually memory leaks.
This PR fixes crashes observed on older Synapse builds introduced with #227. Setting PT_COMPILE_ONLY_MODE is not supported in current or older public Synapse builds, but we should not crash because of it, rather we should advise user to use the latest build.

Fixes serving mode issue; due to error in fastapi
This PR contains mask based BGMV implementation for LoRA embedding instead of index-select of LoRA-B weights. Removing special handling in no LoRA case also.

RuntimeErrors are not observed anymore on habana_main when disable_tensor_cache is used. This PR enables disable_tensor_cache.
On habana_main the slots are calculated by adding an offset to the block which breaks the check for _PAD_SLOT_ID. Reworked it so that in case of _PAD_BLOCK_ID we're automatically inserting the right value.
…a/vllm_v0_6_0_rebase
We were asked on upstream PR to remove our changes from cache_engine.py. This PR does just that, and creates HPUCacheEngine inheriting from CacheEngine, just overriding _allocate_kv_cache method.
…imit prefill batch size (#394) This PR adds following functionality that can be enabled via engine flags: - use_padding_aware_scheduling - vLLM scheduler will now calculate token cost considering padded prefill shape (similar to #109). - max_num_prefill_seqs - padding-aware scheduler will perform an additional check for prefill batch size and will effectively limit prefill batch size at maximum of `max_num_prefill_seqs`. If unset, max prefill batch size will be `max_num_seqs`. Both features are generic and do not require HPU, although they may be specialized for particular vendor's usage. Padding aware scheduling includes padding function selector which selects HPU padding function (considering currently used HPU buckets) if current device is HPU. Otherwise, it will take a product of batch_size x max_seq_len.

…vllm-project#8704) Removing the block manager v1. This is the initial piece of prefix-caching-centric design. In order to achieve prefix-caching-centric design, we need to simplify the code path so that we only use v2 block manager (which has much higher performance on prefix caching).
