From 8c140bee33de2b5f5102e98a2768a22891855ef0 Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Wed, 24 Apr 2024 20:20:11 +1000 Subject: [PATCH] ls-ecaps: Correct the link state reporting PCIe r6.0, sec 7.9.26.4.2 "Link IDE Stream Status Register defines" the link state as: 0000b Insecure 0010b Secure The same definition applies to selective streams as well. The existing code wrongly assumes "secure" is 0001b, fix that for both link and selective streams. While at this, add missing "Selective IDE for Configuration Requests Enable". Also fix the base and limit parsing for the memory and RID ranges. Fixes: 42fc4263ec0e ("ls-ecaps: Add decode support for IDE Extended Capability") Signed-off-by: Alexey Kardashevskiy --- lib/header.h | 1 + ls-ecaps.c | 13 +++++++++---- tests/cap-ide | 12 ++++++------ 3 files changed, 16 insertions(+), 10 deletions(-) diff --git a/lib/header.h b/lib/header.h index 0b0ed9a..031912f 100644 --- a/lib/header.h +++ b/lib/header.h @@ -1464,6 +1464,7 @@ #define PCI_IDE_SEL_CTL_TX_AGGR_PR(x) (((x) >> 4) & 0x3) /* Tx Aggregation Mode PR */ #define PCI_IDE_SEL_CTL_TX_AGGR_CPL(x) (((x) >> 6) & 0x3) /* Tx Aggregation Mode CPL */ #define PCI_IDE_SEL_CTL_PCRC_EN 0x100 /* PCRC Enable */ +#define PCI_IDE_SEL_CTL_CFG_EN 0x200 /* Selective IDE for Configuration Requests Enable */ #define PCI_IDE_SEL_CTL_PART_ENC(x) (((x) >> 10) & 0xf) /* Partial Header Encryption Mode */ #define PCI_IDE_SEL_CTL_ALG(x) (((x) >> 14) & 0x1f) /* Selected Algorithm */ #define PCI_IDE_SEL_CTL_TC(x) (((x) >> 19) & 0x7) /* Traffic Class */ diff --git a/ls-ecaps.c b/ls-ecaps.c index b40ba72..2340084 100644 --- a/ls-ecaps.c +++ b/ls-ecaps.c @@ -1512,7 +1512,7 @@ static void cap_ide(struct device *d, int where) { const char *hdr_enc_mode[] = { "no", "17:2", "25:2", "33:2", "41:2" }; - const char *stream_state[] = { "insecure", "secure" }; + const char *stream_state[] = { "insecure", "reserved", "secure" }; const char *aggr[] = { "-", "=2", "=4", "=8" }; u32 l, l2, linknum = 0, selnum = 0, addrnum, off, i, j; char buf1[16], buf2[16], offs[16]; @@ -1613,7 +1613,7 @@ cap_ide(struct device *d, int where) // Selective IDE Stream Control Register l = get_conf_long(d, off); - printf("\t\t%sSelectiveIDE#%d Ctl: En%c NPR%s PR%s CPL%s PCRC%c HdrEnc=%s Alg='%s' TC%d ID%d%s\n", + printf("\t\t%sSelectiveIDE#%d Ctl: En%c NPR%s PR%s CPL%s PCRC%c CFG%c HdrEnc=%s Alg='%s' TC%d ID%d%s\n", offstr(offs, off), i, FLAG(l, PCI_IDE_SEL_CTL_EN), @@ -1621,6 +1621,7 @@ cap_ide(struct device *d, int where) aggr[PCI_IDE_SEL_CTL_TX_AGGR_PR(l)], aggr[PCI_IDE_SEL_CTL_TX_AGGR_CPL(l)], FLAG(l, PCI_IDE_SEL_CTL_PCRC_EN), + FLAG(l, PCI_IDE_SEL_CTL_CFG_EN), TABLE(hdr_enc_mode, PCI_IDE_SEL_CTL_PART_ENC(l), buf1), ide_alg(buf2, sizeof(buf2), PCI_IDE_SEL_CTL_ALG(l)), PCI_IDE_SEL_CTL_TC(l), @@ -1664,14 +1665,18 @@ cap_ide(struct device *d, int where) l = get_conf_long(d, off); limit = get_conf_long(d, off + 4); + limit <<= 32; + limit |= (PCI_IDE_SEL_ADDR_1_LIMIT_LOW(l) << 20) | 0xFFFFF; base = get_conf_long(d, off + 8); + base <<= 32; + base |= PCI_IDE_SEL_ADDR_1_BASE_LOW(l) << 20; printf("\t\t%sSelectiveIDE#%d RID#%d: Valid%c Base=%lx Limit=%lx\n", offstr(offs, off), i, j, FLAG(l, PCI_IDE_SEL_ADDR_1_VALID), - (base << 32) | PCI_IDE_SEL_ADDR_1_BASE_LOW(l), - (limit << 32) | PCI_IDE_SEL_ADDR_1_LIMIT_LOW(l)); + base, + limit); off += 12; } } diff --git a/tests/cap-ide b/tests/cap-ide index 01a9e09..edae551 100644 --- a/tests/cap-ide +++ b/tests/cap-ide @@ -79,10 +79,10 @@ e1:00.0 Class 0800: Device aaaa:bbbb IDECap: Lnk=0 Sel=1 FlowThru- PartHdr- Aggr- PCPC- IDE_KM+ Alg='AES-GCM-256-96b' TCs=8 TeeLim+ IDECtl: FTEn- SelectiveIDE#0 Cap: RID#=1 - SelectiveIDE#0 Ctl: En- NPR- PR- CPL- PCRC- HdrEnc=no Alg='AES-GCM-256-96b' TC0 ID0 - SelectiveIDE#0 Sta: insecure RecvChkFail- - SelectiveIDE#0 RID: Valid- Base=0 Limit=0 SegBase=0 - SelectiveIDE#0 RID#0: Valid- Base=0 Limit=0 + SelectiveIDE#0 Ctl: En+ NPR- PR- CPL- PCRC- CFG- HdrEnc=no Alg='AES-GCM-256-96b' TC0 ID0 Default + SelectiveIDE#0 Sta: secure RecvChkFail- + SelectiveIDE#0 RID: Valid+ Base=0 Limit=ffff SegBase=0 + SelectiveIDE#0 RID#0: Valid+ Base=0 Limit=ffffffffffffffff Capabilities: [e00 v2] Data Object Exchange DOECap: IntSup- DOECtl: IntEn- @@ -219,8 +219,8 @@ f0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 810: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 820: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 830: 30 00 01 e0 42 e0 00 01 00 00 00 00 01 00 00 00 -840: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 -850: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 +840: 01 00 40 00 02 00 00 00 00 ff ff 00 01 00 00 00 +850: 01 00 f0 ff ff ff ff ff 00 00 00 00 00 00 00 00 860: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 870: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 880: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 -- 2.39.2
