Change the ppc440_sdram model to a QOM class derived from the PPC4xx-dcr-device and name it ppc4xx-sdram-ddr2. This is mostly modelling the DDR2 SDRAM controller found in the 460EX (used on the sam460ex board). Newer SoCs (regardless of their PPC core, e.g. 405EX) may have this controller but we only emulate enough of it for the sam460ex u-boot firmware.

2022-07-28hw/ppc/ppc440_uc: Initialize length passed to cpu_physical_memory_map()Peter Maydell1-1/+4
In dcr_write_dma(), there is code that uses cpu_physical_memory_map() to implement a DMA transfer. That function takes a 'plen' argument, which points to a hwaddr which is used for both input and output: the caller must set it to the size of the range it wants to map, and on return it is updated to the actual length mapped. The dcr_write_dma() code fails to initialize rlen and wlen, so will end up mapping an unpredictable amount of memory. Initialize the length values correctly, and check that we managed to map the entire range before using the fast-path memmove(). This was spotted by Coverity, which points out that we never initialized the variables before using them.

2022-06-20ppc: fix boot with sam460exMichael S. Tsirkin1-0/+8
Recent changes to pcie_host corrected size of its internal region to match what it expects: only the low 28 bits are ever decoded. Previous code just ignored bit 29 (if size was 1 << 29) in the address which does not make much sense. We are now asserting on size > 1 << 28 instead, but PPC 4xx actually allows guest to configure different sizes, and some firmwares seem to set it to 1 << 29. This caused e.g. qemu-system-ppc -M sam460ex to exit with an assert when the guest writes a value to CFGMSK register when trying to map config space. This is done in the board firmware in ppc4xx_init_pcie_port() in roms/u-boot-sam460ex/arch/powerpc/cpu/ppc4xx/4xx_pcie.c It's not clear what the proper fix should be but for now let's force the size to 256MB, so anything outside the expected address range is ignored.

In dcr_write_pcie() we take the iothread lock around a call to pcie_host_mmcfg_udpate(). This is an incorrect attempt to deal with the bug fixed in commit 235352ee6e73d7716, where we were not taking the iothread lock before calling device dcr read/write functions. (It's not sufficient locking, because although the other cases in the switch statement won't assert, there is no locking which prevents multiple guest CPUs from trying to access the PPC460EXPCIEState struct at the same time and corrupting data.) Unfortunately with commit 235352ee6e73d7716 we are now trying to recursively take the iothread lock, which will assert: $ qemu-system-ppc -M sam460ex --display none ** ERROR:/home/petmay01/linaro/qemu-from-laptop/qemu/cpus.c:1830:qemu_mutex_lock_iothread_impl: assertion failed: (!qemu_mutex_iothread_locked()) Aborted (core dumped) Remove the locking within dcr_write_pcie().

2019-08-16Include sysemu/reset.h a lot lessMarkus Armbruster1-0/+1
In my "build everything" tree, changing sysemu/reset.h triggers a recompile of some 2600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). The main culprit is hw/hw.h, which supposedly includes it for convenience. Include sysemu/reset.h only where it's needed. Touching it now recompiles less than 200 objects.

2019-02-04ppc440: Avoid reporting error when reading non-existent RAM slotBALATON Zoltan1-2/+4
When reading base register of RAM slot with no RAM we should not try to calculate register value because that will result printing an error due to invalid RAM size. Just return 0 without the error in this case. Signed-off-by: BALATON Zoltan <balaton@eik.bme.hu> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2019-02-04sam460ex: Fix support for memory larger than 1GBBALATON Zoltan1-10/+12
Fix the encoding of larger memory modules in the SoC registers which allows specifying more than 1GB memory for sam460ex. Well, only 2GB due to SoC and firmware restrictions which was the only missing value compared to what the real hardware supports. The SoC should support up to 4GB but when setting that the firmware hangs during memory test. This may be an overflow bug in the firmware which I did not try to debug but this may affect real hardware as well.

2019-02-04ppc4xx: Pass array index to function instead of pointer into the arrayBALATON Zoltan1-20/+16
The sdram_set_bcr() function in ppc440_uc.c takes a pointer into an array then calculates its index from that. It's simpler and easier to just pass the index which simplifies both the function and its callers. Do similar cleanup in ppc4xx_devs.c to similar function.

They are not used outside their files so don't clash but they are also not identical so rename the ppc440 specific one to distinguish them.

2018-11-08hw/ppc/ppc440_uc: Remove dead code in sdram_size()Peter Maydell1-5/+1
Coverity points out in CID 1390588 that the test for sh == 0 in sdram_size() can never fire, because we calculate sh with sh = 1024 - ((bcr >> 6) & 0x3ff); which must result in a value between 1 and 1024 inclusive. Without the relevant manual for the SoC, we're not completely sure of the correct behaviour here, but we can remove the dead code without changing how QEMU currently behaves.

into staging ppc patch queue 2018-07-03 Here's a last minue pull request before today's soft freeze. Ideally I would have sent this earlier, but I was waiting for a couple of extra fixes I knew were close. And the freeze crept up on me, like always. Most of the changes here are bugfixes in any case. There are some cleanups as well, which have been in my staging tree for a little while. There are a couple of truly new features (some extensions to the sam460ex platform), but these are low risk, since they only affect a new and not really stabilized machine type anyway. Higlights are: * Mac platform improvements from Mark Cave-Ayland * Sam460ex improvements from BALATON Zoltan et al. * XICS interrupt handler cleanups from Cédric Le Goater * TCG improvements for atomic loads and stores from Richard Henderson * Assorted other bugfixes # gpg: Signature made Tue 03 Jul 2018 06:55:22 BST # gpg: using RSA key 6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-3.0-20180703: (35 commits) ppc: Include vga cirrus card into the compiling process target/ppc: Relax reserved bitmask of indexed store instructions target/ppc: set is_jmp on ppc_tr_breakpoint_check spapr: compute default value of "hpt-max-page-size" later target/ppc/kvm: don't pass cpu to kvm_get_smmu_info() target/ppc/kvm: get rid of kvm_get_fallback_smmu_info() ppc440_uc: Basic emulation of PPC440 DMA controller sam460ex: Add RTC device hw/timer: Add basic M41T80 emulation ppc4xx_i2c: Rewrite to model hardware more closely hw/ppc: Give sam46ex its own config option fpu_helper.c: fix setting FPSCR[FI] bit target/ppc: Implement the rest of gen_st_atomic target/ppc: Implement the rest of gen_ld_atomic target/ppc: Use atomic min/max helpers target/ppc: Use MO_ALIGN for EXIWX and ECOWX target/ppc: Split out gen_st_atomic target/ppc: Split out gen_ld_atomic target/ppc: Split out gen_load_locked target/ppc: Tidy gen_conditional_store ...
