I saw a flicker when booting xe, and it's very likely that the original FB was not mapped at the same place when inheriting, fix it. Signed-off-by:

The comparison with < 0 suggests that the memory device access should be signed to handle underflow. This makes it work more reliably. As a result, the max refcount is now S32_MAX instead. Signed-off-by:

At present the interrupts are enabled while initializing the last GT. But this is incorrect for a Multi-GT platform, as root GT initialization will fail with interrupt disabled. Interrupts are required for the GuC submission triggered during initialization. Enable the interrupt during the root GT initialization. Signed-off-by:

Leave the types as u64, but cast the pointers to unsigned long before assigning so the compiler doesn't throw warning about casting a pointer to integer of different size. Also, size_t should use %zu, not %ld. Signed-off-by:

writeq() and readq() and other functions working on 64 bit variables are not provided by 32b arch. For that it's needed to choose between linux/io-64-nonatomic-hi-lo.h and linux/io-64-nonatomic-lo-hi.h, spliting the read/write in 2 accesses. For xe driver, it doesn't matter much, so just choose one and include in xe_mmio.h. This also removes some ifdef CONFIG_64BIT we had around because of the missing 64bit functions. Signed-off-by:

This adds support for stolen memory, with the same allocator as vram_mgr. This allows us to skip a whole lot of copy-paste, by re-using parts of xe_ttm_vram_mgr. The stolen memory may be bound using VM_BIND, so it performs like any other memory region. We should be able to map a stolen BO directly using the physical memory location instead of through GGTT even on old platforms, but I don't know what the effects are on coherency. Signed-off-by:

When a job is inflight we may access memory to read the hardware seqno. All user jobs have VM open which has a ref but kernel jobs do not require VM so it is possible to not have memory ref. To avoid this, take a memory ref on kernel job creation. Signed-off-by:

Rather than a constant check on proto and wait not busy, let's wait for the expected success and then check the protocol afterwards. With this, we can now use the regular xe_mmio_wait32 and kill this local need for the wait_for. Signed-off-by:

This is already useful because it avoids some extra reads where registers might have changed after the timeout decision. But also, it will be important to end the kill of i915's wait_for. Signed-off-by:

Then, move the i915_utils.h include to its user. The overall goal is to kill all the usages of the i915_utils stuff. Yes, wait_for also depends on <linux/delay.h>, so they go together to where it is needed. It will be likely needed anyway directly for udelay or usleep_range. Signed-off-by:
