7 | and "4.10.2 SD Status": | ||
8 | |||
9 | The SD Status contains status bits that are related to the SD Memory Card | ||
10 | proprietary features and may be used for future application-specific usage. | ||
11 | The size of the SD Status is one data block of 512 bit. The content of this | ||
12 | register is transmitted to the Host over the DAT bus along with a 16-bit CRC. | ||
13 | |||
14 | Thus the 16-bit CRC goes at offset 64. | ||

1 | In commit d81ce0ef2c4f105 we added an extra float_status field | 1 | From: Damien Hedde <damien.hedde@greensocs.com> |
---|---|---|---|
2 | fp_status_fp16 for Arm, but forgot to initialize it correctly | ||
3 | by setting it to float_tininess_before_rounding. This currently | ||
4 | will only cause problems for the new V8_FP16 feature, since the | ||
5 | float-to-float conversion code doesn't use it yet. The effect | ||
6 | would be that we failed to set the Underflow IEEE exception flag | ||
7 | in all the cases where we should. | ||
8 | 2 | ||
9 | Add the missing initialization. | 3 | As of now, cryptographic instructions ISAR fields are never cleared so |
4 | we can end up with a cpu with cryptographic instructions but no | ||
5 | floating-point/neon instructions which is not a possible configuration | ||
6 | according to Arm specifications. | ||
10 | 7 | ||
11 | Fixes: d81ce0ef2c4f105 | 8 | In QEMU, we have 3 kinds of cpus regarding cryptographic instructions: |
12 | Cc: qemu-stable@nongnu.org | 9 | + no support |
10 | + cortex-a57/a72: cryptographic extension is optional, | ||
11 | floating-point/neon is not. | ||
12 | + cortex-a53: crytographic extension is optional as well as | ||
13 | floating-point/neon. But cryptographic requires | ||
14 | floating-point/neon support. | ||
15 | |||
16 | Therefore we can safely clear the ISAR fields when neon is disabled. | ||
17 | |||
18 | Note that other Arm cpus seem to follow this. For example cortex-a55 is | ||
19 | like cortex-a53 and cortex-a76/cortex-a710 are like cortex-a57/a72. | ||

3 | The Record bit in the Context Descriptor tells the SMMU to report fault | ||
4 | events to the event queue. Since we don't cache the Record bit at the | ||
5 | moment, access faults from a cached Context Descriptor are never | ||
6 | reported. Store the Record bit in the cached SMMUTransCfg. | ||

1 | The Arm FEAT_TTL architectural feature allows the guest to provide an | ||
2 | optional hint in an AArch64 TLB invalidate operation about which | ||
3 | translation table level holds the leaf entry for the address being | ||
4 | invalidated. QEMU's TLB implementation doesn't need that hint, and | ||
5 | we correctly ignore the (previously RES0) bits in TLB invalidate | ||
6 | operation values that are now used for the TTL field. So we can | ||
7 | simply advertise support for it in our 'max' CPU. | ||

2 | converts exactly to the largest or smallest integer that | 2 | admirably clear on the guarantees it provides software, but slightly |
3 | fits in to the result type, this is not an overflow. | 3 | more obscure on what that means for implementations. The description |
4 | In this situation we were producing the correct result value, | 4 | of the equivalent SMMU feature in the SMMU specification (IHI0070D.b |
5 | but were incorrectly setting the Invalid flag. | 5 | section 3.21.1) is perhaps a bit more detailed and includes some |

7 | 0x41dfffffffc00000 should produce 0x7fffffff and set no flags. | 7 | feature is slightly tighter than the CPU version: the CPU is permitted |
8 | to raise TLB Conflict aborts in some situations that the SMMU may | ||
9 | not. This doesn't matter for QEMU because we don't want to do TLB | ||
10 | Conflict aborts anyway.) | ||
8 | 11 | ||
9 | Fix the boundary case to take the right half of the if() | 12 | The informal summary of FEAT_BBM is that it is about permitting an OS |
10 | statements. | 13 | to switch a range of memory between "covered by a huge page" and |
14 | "covered by a sequence of normal pages" without having to engage in | ||
15 | the 'break-before-make' dance that has traditionally been | ||
16 | necessary. The 'break-before-make' sequence is: | ||

14 | 24 | ||
15 | Cc: qemu-stable@nongnu.org | 25 | The point of this is to ensure that no TLB can simultaneously contain |
16 | Fixes: ab52f973a50 | 26 | TLB entries for the old and the new entry, which would traditionally |
27 | be UNPREDICTABLE (allowing the CPU to generate a TLB Conflict fault | ||
28 | or to use a random mishmash of values from the old and the new | ||
29 | entry). FEAT_BBM level 2 says "for the specific case where the only | ||
30 | thing that changed is the size of the block, the TLB is guaranteed | ||
31 | not to do weird things even if there are multiple entries for an | ||
32 | address", which means that software can now do: | ||
33 | |||
34 | * replace old translation table entry with new entry | ||
35 | * DSB | ||
36 | * broadcast TLB invalidate | ||
37 | * DSB | ||
38 | |||
39 | As the SMMU spec notes, valid ways to do this include: | ||
40 | |||
41 | * if there are multiple entries in the TLB for an address, | ||
42 | choose one of them and use it, ignoring the others | ||
43 | * if there are multiple entries in the TLB for an address, | ||
44 | throw them all out and do a page table walk to get a new one | ||
45 | |||
46 | QEMU's page table walk implementation for Arm CPUs already meets the | ||
47 | requirements for FEAT_BBM level 2. When we cache an entry in our TCG | ||
48 | TLB, we do so only for the specific (non-huge) page that the address | ||
49 | is in, and there is no way for the TLB data structure to ever have | ||
50 | more than one TLB entry for that page. (We handle huge pages only in | ||
51 | that we track what part of the address space is covered by huge pages | ||
52 | so that a TLB invalidate operation for an address in a huge page | ||
53 | results in an invalidation of the whole TLB.) We ignore the Contiguous | ||
54 | bit in page table entries, so we don't have to do anything for the | ||
55 | parts of FEAT_BBM that deal with changis to the Contiguous bit. | ||
56 | |||
57 | FEAT_BBM level 2 also requires that the nT bit in block descriptors | ||
58 | must be ignored; since commit 39a1fd25287f5dece5 we do this. | ||
59 | |||
60 | It's therefore safe for QEMU to advertise FEAT_BBM level 2 by | ||
61 | setting ID_AA64MMFR2_EL1.BBM to 2. | ||

1 | Usually the logging of the CPU state produced by -d cpu is sufficient | 1 | The Arm SMMUv3 includes an optional feature equivalent to the CPU |
---|---|---|---|
2 | to diagnose problems, but sometimes you want to see the state of | 2 | FEAT_BBM, which permits an OS to switch a range of memory between |
3 | the floating point registers as well. We don't want to enable that | 3 | "covered by a huge page" and "covered by a sequence of normal pages" |
4 | by default as it adds a lot of extra data to the log; instead, | 4 | without having to engage in the traditional 'break-before-make' |
5 | allow it to be optionally enabled via -d fpu. | 5 | dance. (This is particularly important for the SMMU, because devices |
6 | performing I/O through an SMMU are less likely to be able to cope with | ||
7 | the window in the sequence where an access results in a translation | ||
8 | fault.) The SMMU spec explicitly notes that one of the valid ways to | ||
9 | be a BBM level 2 compliant implementation is: | ||
10 | * if there are multiple entries in the TLB for an address, | ||
11 | choose one of them and use it, ignoring the others | ||
12 | |||
13 | Our SMMU TLB implementation (unlike our CPU TLB) does allow multiple | ||
14 | TLB entries for an address, because the translation table level is | ||
15 | part of the SMMUIOTLBKey, and so our IOTLB hashtable can include | ||
16 | entries for the same address where the leaf was at different levels | ||
17 | (i.e. both hugepage and normal page). Our TLB lookup implementation in | ||
18 | smmu_iotlb_lookup() will always find the entry with the lowest level | ||
19 | (i.e. it prefers the hugepage over the normal page) and ignore any | ||
20 | others. TLB invalidation correctly removes all TLB entries matching | ||
21 | the specified address or address range (unless the guest specifies the | ||
22 | leaf level explicitly, in which case it gets what it asked for). So we | ||
23 | can validly advertise support for BBML level 2. | ||
24 | |||
25 | Note that we still can't yet advertise ourselves as an SMMU v3.2, | ||
26 | because v3.2 requires support for the S2FWB feature, which we don't | ||
27 | yet implement. | ||
