Ard Biesheuvel c1993157bd ArmVirtPkg: increase memory preallocations to reduce region count ... This updates the sizes of the preallocated regions so that the number of distinct regions that exists is minimal at the time we exit boot services. For a typical run of the ArmVirtQemu platform, we get the following utilization numbers: Reserved : 4 Pages (16,384 Bytes) LoaderCode: 210 Pages (860,160 Bytes) LoaderData: 0 Pages (0 Bytes) BS_Code : 355 Pages (1,454,080 Bytes) BS_Data : 6,807 Pages (27,881,472 Bytes) RT_Code : 112 Pages (458,752 Bytes) RT_Data : 288 Pages (1,179,648 Bytes) ACPI_Recl : 32 Pages (131,072 Bytes) ACPI_NVS : 0 Pages (0 Bytes) MMIO : 16,385 Pages (67,112,960 Bytes) MMIO_Port : 0 Pages (0 Bytes) PalCode : 0 Pages (0 Bytes) Available : 123,264 Pages (504,889,344 Bytes) -------------- Total Memory: 511 MB (536,854,528 Bytes) Strangely enough, the allocation count of 20,000 pages for BS_Data does not result in those regions being merged. For BS_Code, RT_Code and RT_Data, the increased preallocation results in the following reduction in the number of regions. 0x000040000000-0x00004000ffff [Loader Data | | | | | |WB|WT|WC|UC] - 0x000040010000-0x0000b66bbfff [Conventional Memory| | | | | |WB|WT|WC|UC] - 0x0000b66bc000-0x0000b66d0fff [Loader Data | | | | | |WB|WT|WC|UC] - 0x0000b66d1000-0x0000b6f6bfff [Loader Code | | | | | |WB|WT|WC|UC] - 0x0000b6f6c000-0x0000b6f6ffff [Reserved | | | | | |WB|WT|WC|UC]* - 0x0000b6f70000-0x0000b6f8ffff [Runtime Code |RUN| | | | |WB|WT|WC|UC]* - 0x0000b6f90000-0x0000b6faffff [ACPI Reclaim Memory| | | | | |WB|WT|WC|UC]* - 0x0000b6fb0000-0x0000b6fcffff [Runtime Code |RUN| | | | |WB|WT|WC|UC]* - 0x0000b6fd0000-0x0000b701ffff [Runtime Data |RUN| | | | |WB|WT|WC|UC]* - 0x0000b7020000-0x0000b702ffff [Runtime Code |RUN| | | | |WB|WT|WC|UC]* - 0x0000b7030000-0x0000b70cffff [Runtime Data |RUN| | | | |WB|WT|WC|UC]* - 0x0000b70d0000-0x0000b70dffff [Runtime Code |RUN| | | | |WB|WT|WC|UC]* + 0x000040010000-0x0000b680bfff [Conventional Memory| | | | | |WB|WT|WC|UC] + 0x0000b680c000-0x0000b6820fff [Loader Data | | | | | |WB|WT|WC|UC] + 0x0000b6821000-0x0000b70bbfff [Loader Code | | | | | |WB|WT|WC|UC] + 0x0000b70bc000-0x0000b70bffff [Reserved | | | | | |WB|WT|WC|UC]* + 0x0000b70c0000-0x0000b70dffff [ACPI Reclaim Memory| | | | | |WB|WT|WC|UC]* 0x0000b70e0000-0x0000b9f87fff [Conventional Memory| | | | | |WB|WT|WC|UC] 0x0000b9f88000-0x0000bb921fff [Boot Data | | | | | |WB|WT|WC|UC] 0x0000bb922000-0x0000bb9bffff [Conventional Memory| | | | | |WB|WT|WC|UC] 0x0000bb9c0000-0x0000bbbb0fff [Boot Data | | | | | |WB|WT|WC|UC] 0x0000bbbb1000-0x0000bbbeffff [Conventional Memory| | | | | |WB|WT|WC|UC] 0x0000bbbf0000-0x0000bbf1ffff [Boot Data | | | | | |WB|WT|WC|UC] - 0x0000bbf20000-0x0000bedfffff [Conventional Memory| | | | | |WB|WT|WC|UC] - 0x0000bee00000-0x0000bf71ffff [Loader Data | | | | | |WB|WT|WC|UC] - 0x0000bf720000-0x0000bf7ccfff [Conventional Memory| | | | | |WB|WT|WC|UC] - 0x0000bf7cd000-0x0000bf92ffff [Boot Code | | | | | |WB|WT|WC|UC] - 0x0000bf930000-0x0000bf93ffff [Runtime Code |RUN| | | | |WB|WT|WC|UC]* - 0x0000bf940000-0x0000bf95ffff [Conventional Memory| | | | | |WB|WT|WC|UC] - 0x0000bf960000-0x0000bf97ffff [Runtime Data |RUN| | | | |WB|WT|WC|UC]* + 0x0000bbf20000-0x0000bebfffff [Conventional Memory| | | | | |WB|WT|WC|UC] + 0x0000bec00000-0x0000bf51ffff [Loader Data | | | | | |WB|WT|WC|UC] + 0x0000bf520000-0x0000bf65cfff [Conventional Memory| | | | | |WB|WT|WC|UC] + 0x0000bf65d000-0x0000bf7bffff [Boot Code | | | | | |WB|WT|WC|UC] + 0x0000bf7c0000-0x0000bf84ffff [Runtime Code |RUN| | | | |WB|WT|WC|UC]* + 0x0000bf850000-0x0000bf86ffff [Conventional Memory| | | | | |WB|WT|WC|UC] + 0x0000bf870000-0x0000bf97ffff [Runtime Data |RUN| | | | |WB|WT|WC|UC]* 0x0000bf980000-0x0000bf997fff [Conventional Memory| | | | | |WB|WT|WC|UC] 0x0000bf998000-0x0000bf99afff [Boot Data | | | | | |WB|WT|WC|UC] 0x0000bf99b000-0x0000bf9aefff [Conventional Memory| | | | | |WB|WT|WC|UC] Contributed-under: TianoCore Contribution Agreement 1.0 Reviewed-by: Laszlo Ersek <lersek@redhat.com> Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@17554 6f19259b-4bc3-4df7-8a09-765794883524		2015-06-03 16:11:47 +00:00
