This test adds a regression test for the case where BCL and nb_sectors are both 0. Flesh out the CDROM tests by: (1) Allowing the test to specify a BCL (2) Allowing the buffer comparison test to compare a 0-size buffer (3) Fix the BCL specification in libqos (It is LE, not BE) (4) Add a nice human-readable message for future SCSI command additions Signed-off-by: John Snow Reviewed-by: Kevin Wolf Message-id: 1477970211-25754-4-git-send-email-jsnow@redhat.com [Line length edit --js] Signed-off-by: John Snow --- tests/ahci-test.c | 36 +++++++++++++++++++++++++++++------- tests/libqos/ahci.c | 28 +++++++++++++++++++++------- tests/libqos/ahci.h | 17 ++++++++++------- 3 files changed, 60 insertions(+), 21 deletions(-) (limited to 'tests') diff --git a/tests/ahci-test.c b/tests/ahci-test.c index a271cad7ab..0b1b6f7201 100644 --- a/tests/ahci-test.c +++ b/tests/ahci-test.c @@ -1473,8 +1473,13 @@ static int ahci_cb_cmp_buff(AHCIQState *ahci, AHCICommand *cmd, const AHCIOpts *opts) { unsigned char *tx = opts->opaque; - unsigned char *rx = g_malloc0(opts->size); + unsigned char *rx; + if (!opts->size) { + return 0; + } + + rx = g_malloc0(opts->size); bufread(opts->buffer, rx, opts->size); g_assert_cmphex(memcmp(tx, rx, opts->size), ==, 0); g_free(rx); @@ -1482,7 +1487,8 @@ static int ahci_cb_cmp_buff(AHCIQState *ahci, AHCICommand *cmd, return 0; } -static void ahci_test_cdrom(int nsectors, bool dma) +static void ahci_test_cdrom(int nsectors, bool dma, uint8_t cmd, + bool override_bcl, uint16_t bcl) { AHCIQState *ahci; unsigned char *tx; @@ -1493,6 +1499,8 @@ static void ahci_test_cdrom(int nsectors, bool dma) .atapi = true, .atapi_dma = dma, .post_cb = ahci_cb_cmp_buff, + .set_bcl = override_bcl, + .bcl = bcl, }; uint64_t iso_size = ATAPI_SECTOR_SIZE * (nsectors + 1); @@ -1506,7 +1514,7 @@ static void ahci_test_cdrom(int nsectors, bool dma) "-device ide-cd,drive=drive0 ", iso); /* Build & Send AHCI command */ - ahci_exec(ahci, ahci_port_select(ahci), CMD_ATAPI_READ_10, &opts); + ahci_exec(ahci, ahci_port_select(ahci), cmd, &opts); /* Cleanup */ g_free(tx); @@ -1514,24 +1522,36 @@ static void ahci_test_cdrom(int nsectors, bool dma) remove_iso(fd, iso); } +static void ahci_test_cdrom_read10(int nsectors, bool dma) +{ + ahci_test_cdrom(nsectors, dma, CMD_ATAPI_READ_10, false, 0); +} + static void test_cdrom_dma(void) { - ahci_test_cdrom(1, true); + ahci_test_cdrom_read10(1, true); } static void test_cdrom_dma_multi(void) { - ahci_test_cdrom(3, true); + ahci_test_cdrom_read10(3, true); } static void test_cdrom_pio(void) { - ahci_test_cdrom(1, false); + ahci_test_cdrom_read10(1, false); } static void test_cdrom_pio_multi(void) { - ahci_test_cdrom(3, false); + ahci_test_cdrom_read10(3, false); +} + +/* Regression test: Test that a READ_CD command with a BCL of 0 but a size of 0 + * completes as a NOP instead of erroring out. */ +static void test_atapi_bcl(void) +{ + ahci_test_cdrom(0, false, CMD_ATAPI_READ_CD, true, 0); } /******************************************************************************/ @@ -1823,6 +1843,8 @@ int main(int argc, char **argv) qtest_add_func("/ahci/cdrom/pio/single", test_cdrom_pio); qtest_add_func("/ahci/cdrom/pio/multi", test_cdrom_pio_multi); + qtest_add_func("/ahci/cdrom/pio/bcl", test_atapi_bcl); + ret = g_test_run(); /* Cleanup */ diff --git a/tests/libqos/ahci.c b/tests/libqos/ahci.c index 5180d65279..0e9354bf13 100644 --- a/tests/libqos/ahci.c +++ b/tests/libqos/ahci.c @@ -633,7 +633,8 @@ void ahci_exec(AHCIQState *ahci, uint8_t port, /* Command creation */ if (opts->atapi) { - cmd = ahci_atapi_command_create(op); + uint16_t bcl = opts->set_bcl ? opts->bcl : ATAPI_SECTOR_SIZE; + cmd = ahci_atapi_command_create(op, bcl); if (opts->atapi_dma) { ahci_command_enable_atapi_dma(cmd); } @@ -864,16 +865,12 @@ AHCICommand *ahci_command_create(uint8_t command_name) return cmd; } -AHCICommand *ahci_atapi_command_create(uint8_t scsi_cmd) +AHCICommand *ahci_atapi_command_create(uint8_t scsi_cmd, uint16_t bcl) { AHCICommand *cmd = ahci_command_create(CMD_PACKET); cmd->atapi_cmd = g_malloc0(16); cmd->atapi_cmd[0] = scsi_cmd; - /* ATAPI needs a PIO transfer chunk size set inside of the LBA registers. - * The block/sector size is a natural default. */ - cmd->fis.lba_lo[1] = ATAPI_SECTOR_SIZE >> 8 & 0xFF; - cmd->fis.lba_lo[2] = ATAPI_SECTOR_SIZE & 0xFF; - + stw_le_p(&cmd->fis.lba_lo[1], bcl); return cmd; } @@ -901,12 +898,17 @@ static void ahci_atapi_command_set_offset(AHCICommand *cmd, uint64_t lba) switch (cbd[0]) { case CMD_ATAPI_READ_10: + case CMD_ATAPI_READ_CD: g_assert_cmpuint(lba, <=, UINT32_MAX); stl_be_p(&cbd[2], lba); break; default: /* SCSI doesn't have uniform packet formats, * so you have to add support for it manually.
