Subject: [PULL v2 08/16] hw/arm/aspeed: Correct DRAM container region size
Date: Wed, 10 Jun 2020 15:10:03 +0200 [thread overview]
Message-ID: <20200610131011.1941209-9-laurent@vivier.eu> (raw)
In-Reply-To: <20200610131011.1941209-1-laurent@vivier.eu>
From: Philippe Mathieu-Daudé <f4bug@amsat.org>
memory_region_set_size() handle the 16 Exabytes limit by
special-casing the UINT64_MAX value. This is not a problem
for the 32-bit maximum, 4 GiB.
By using the UINT32_MAX value, the aspeed-ram-container
MemoryRegion ends up missing 1 byte:
$ qemu-system-arm -M ast2600-evb -S -monitor stdio
(qemu) info mtree
address-space: aspeed.fmc-ast2600-dma-dram
0000000080000000-000000017ffffffe (prio 0, i/o): aspeed-ram-container
0000000080000000-00000000bfffffff (prio 0, ram): ram
00000000c0000000-ffffffffffffffff (prio 0, i/o): max_ram
Fix by using the correct value. We now have:
address-space: aspeed.fmc-ast2600-dma-dram
0000000080000000-000000017fffffff (prio 0, i/o): aspeed-ram-container
0000000080000000-00000000bfffffff (prio 0, ram): ram
00000000c0000000-ffffffffffffffff (prio 0, i/o): max_ram
